You have to get java basics under your belt and then you have to learn the Android IDE and only then can you get your feet wet into actual Android apps and coding them.
So is it worth it.
Here is my answer: it depends.
Why does it depend Charlie?
So here is what my logic is based on.
When you set out to learn a new coding language you have a lot of worries on your hands:
Keeping up with the updates
My close friend makes a good video here about number 2 (time invested) by explaining the time it takes people to make an actual Android app themselves.
These are all things that you must overcome when first learning Android development (or any coding language for that matter)
Overcome the initial challenges of it being hard to learn at first
Find the time to learn and practice
Get the right tools for the job
And stay on top of the language’s updates
But if you can do all of this and successfully learn Android, the world is your oyster.
From Idea To Reality
The biggest thing I can say is that when you are proficient enough at anything that is when the real creative side of you comes out. So by the time you are really good at making Android apps the question of “it being worth it” isn’t even a question.
You will be expressing yourself at the deepest level in everything you code and any idea you have will now be possible. You will essentially have equipped yourself with the paint brush you’ve always wanted that can paint the most beautiful painting.
That once crazy app idea you have will then be possible.
That cool program you wanted to make will be makeable.
It all begins to flow.
You just spread your wings and fly 🙂
So yes. Learning Android is certainly worth it!
How Learning To Program Online Changed The World Forever
Online learning and videos really changed the game when it comes to learning to program as fast as possible.
The Best Way To Learn Java Online really is through a code school and the sort because videos offer you the very best in learning pace and management.
Learning Java Online The Right Way
It’s all just if-then-else statements
Language designers dispute about closures, keying in, and amazing abstractions, however in the ultimate end, it’s just ingenious packaging covered around good, old if-then-else assertions.
That’s just about all the hardware offers. Yes, there are op rules for moving data in and out of storage and op rules for arithmetic, but the leftovers is branch or not branch predicated on some comparison.
People that dabble in unnatural intelligence put a far more strange cloak around these if-then-else assertions, but by the end of your day, the smart statistical recommendation engine unit will choose the most significant or smallest value from some matrix of quantities. It shall perform calculations, skim through the list then, declaring, “If this greater, else if this greater, else if this greater,” until it derives its decision.
A lot of the Web is merely data stored in tables
For days gone by 20 years, the term “Internet” has tingled with the assurance of fabulous prosperity, better friendships, cheaper products, faster communication, and everything but an end to cancer tumor. Yet at its main, almost all of the web is a couple of data stored in furniture.
Match.com? A desk of potential times with columns filled up with hair color, faith, and favorite dessert. eBay? From the table of handles a column placed to record the best bid. Personal blogs? One desk with one row for each and every cranky problem. You name it; from the table.
We prefer to think that the web is a mystic wizard with divine knowledge, but it’s nearer to Bob Cratchit, the clerk from Charles Dickens’ “A Holiday Carol,” saving data in big accounting literature filled up with columns. It’s an computerized file clerk, not the technology of an electric Gandalf or Dumbledore.
We see this inside our programming dialects and java tools. Ruby on Rails, one of the very most popular comets to mix the net, is a slender veneer on the database. Specify a worldwide adjustable and Rails creates a column for you since it knows it’s about building a stand in a databases.
Oh, and the top, big development that’s coming twenty years in to the game is the realization that people don’t always need to fill every column of the stand. That’s NoSQL for you. It could make an effort to pretend to be something apart from a desk, but it’s rather a more enlightened stand that accepts openings.
Users have brains of their own
You might feel that the function listener you designed for your program and tagged “save” has something regarding storing a duplicate of the program’s condition to disk. The truth is, users will dsicover it as a magic button that will fix all the blunders in their ruined doc, or an opportunity to increase their 401(k), something to click to start the heavens and lead alive eternal.
Quite simply, we might prefer to think we’ve created the perfect machine, however the users conquer us every right time. For each bulletproof design we create to remove the opportunity of failure, they produce one blend of clicks to send the device crashing without storing anything on disk. For each elegant design, they discover a way to swipe or click everything into oblivion.
There are occasions when users can be wonderful, but also for the most part, they can be unstable and quirky — and can be quite strenuous. Programmers can make an effort to guess how and where these peculiarities will arise when users are met with the outcome of code, but they’ll probably fail. Most users aren’t developers, and requesting a programmer to believe like the common user is similar to asking a kitty to think such as a dog.
This should go beyond simple situations of individual stupidity. Regardless of how ingenious your technology or chic your code, it still must get on. Predicting that users won’t balk at a 140-figure limit for expressing wants and ire is not any easy business.
The majority of what you code won’t be used
Somehow it seems good to learn that your brand-new software can speak XML, CSV, and Aramaic. Pardon me; our execution team wish to know if this may decode Mayan hieroglyphics because we would need that by the finish of 2012. If it generally does not have that feature, we’ll be Alright, but it’ll be so much much easier to have the purchase order authorized if you may provide that. Thanks a lot.
The users, of course, could caution less. They need one button which one button can mistake them even. The beautiful code you wrote to aid the other N-1 buttons could easily get executed when the QA team comes through, but beyond that, there is absolutely no promise the all-nighters and sprints will have been any other thing more than busywork and bureaucracy.
Here is another helpful video on code and it’s use
Developers don’t even obtain the same increase as artists, who is able to always depend on reselling a few copies of these work with their family and parents. Our parents won’t come through and run the excess code on the feature that just needed to be implemented because someone in a brainstorm thought it might be a casino game changer.
These are the truthes of coding and learning online as I learned them myself, I hope this post helped you achieve your dreams as a java developer my friend.
Quick Tutorial For Beginners To Programming Java or Android
So with any tutorial to learn java we must first learn what java is sueful for and how hard it is to learn java the programming language itself.
Java programming language was at the beginning evolved by using solar Microsystems which turned into initiated by way of James Gosling and launched in 1995 as middle issue of sun Microsystems’ Java platform (Java 1.0 [J2SE]).
The modern release of the Java popular edition is Java SE 8. With the advancement of Java and its sizable popularity, more than one configurations were constructed to match diverse types of systems. as an example: J2EE for agency programs, J2ME for mobile applications.
the new J2 variations had been renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write as soon as, Run anywhere.
Here Is A Good Overview Of The Java Programming Language For Beginners
Java Has These Attributes
item orientated − In Java, the whole lot is an item. Java may be without difficulty prolonged when you consider that it’s far based totally on the object model.
Platform impartial − unlike many other programming languages together with C and C++, whilst Java is compiled, it is not compiled into platform particular machine, as a substitute into platform unbiased byte code. This byte code is distributed over the internet and interpreted through the virtual system (JVM) on whichever platform it’s far being run on.
easy − Java is designed to be clean to analyze. in case you apprehend the simple idea of OOP Java, it’d be smooth to master.
comfy − With Java’s secure feature it permits to develop virus-free, tamper-free structures. Authentication strategies are based totally on public-key encryption.
structure-neutral − Java compiler generates an structure-impartial object document format, which makes the compiled code executable on many processors, with the presence of Java runtime system.
portable − Being architecture-neutral and having no implementation based elements of the specification makes Java transportable. Compiler in Java is written in ANSI C with a smooth portability boundary, which is a POSIX subset.
strong − Java makes an attempt to dispose of error prone conditions through emphasizing in particular on compile time error checking and runtime checking.
Multithreaded − With Java’s multithreaded feature it is possible to write down programs that could carry out many duties simultaneously. This layout function lets in the builders to construct interactive applications that could run easily.
Interpreted − Java byte code is translated on the fly to local system instructions and isn’t saved anywhere. The improvement process is more fast and analytical since the linking is an incremental and mild-weight system.
excessive performance − With using just-In-Time compilers, Java permits high overall performance.
disbursed − Java is designed for the dispensed environment of the net.
Dynamic − Java is considered to be greater dynamic than C or C++ considering that it is designed to adapt to an evolving environment. Java packages can convey giant quantity of run-time facts that can be used to affirm and solve accesses to items on run-time.
James Gosling initiated Java language mission in June 1991 for use in considered one of his many set-top field projects. The language, to begin with referred to as ‘Oak’ after an very welltree that stood out of doors Gosling’s workplace, additionally went by way of the call ‘inexperienced’ and ended up later being renamed as Java, from a list of random words.
sun released the first public implementation as Java 1.zero in 1995. It promised Write as soon as, Run everywhere (WORA), offering no-cost run-times on famous structures.
On 13 November, 2006, solar released much of Java as unfastened and open source software program below the terms of the GNU standard Public License (GPL).
On eight might also, 2007, solar finished the procedure, making all of Java’s center code loose and open-supply, other than a small portion of code to which sun did no longer keep the copyright.
I know this as someone who has been coding for a long time. When you are learning a programming language as a beginner you tend to do a lot of short term things. You write code that will only get the job done but won’t last the test of time. Here are some pointers on how to make code that will survive multiple iterations and last you a long time teaching you the real skills of a great programmer!
1. Use automated construct tools
try to use equipment like Ant or Phing to get your source organized, compressed, and deployed. building your whole utility with a unmarried command is a marvelous manner to save you mistakes and omissions that are inherent when performing repetitive duties, and is a usually core pre-considered necessary for automatic testing strategies. I recommend the usage of Phing, it’s a properly-supported construct device for php written to imitate Ant; in case you aren’t familiar with it, take a look at out Shammer C’s article the usage of Phing, the php construct device and Vito Tardia’s article installation and release Your software with Phing.
2. Use Code Documenters
For huge applications spanning numerous classes and namespaces, you must have routinely generated API documentation. this is very useful and keeps the improvement group aware of “what’s what.” And if you work on several projects at the same time, you may discover such documentation a blessing considering you could forget about about structures switching to and fro among initiatives. One such documenter you would possibly keep in mind the usage of is DocBlox.
3. Use a checking out Framework
There are a lots of gear that I without a doubt respect, but by way of a long way the ones I appreciate the most are the frameworks that help automate the checking out technique. trying out (particularly systematic checking out) is vital to every piece of your million dollar utility. correct trying out equipment are PHPUnit and SimpleTest for unit checking out your Hypertext Preprocessor instructions. For GUI testing, I advocate SeleniumHQ equipment.
In this text you noticed an outline of some of the fine practices for writing better code, which includes the use of a coding standard to unify code formatting throughout the complete team, the importance of refactoring and how to embody it, and the usage of expert tools like testing frameworks, code documenters, and model manage to assist control your codebase. in case you’re not following these recommendations already, it’s well worth the effort to undertake them and get your team on track.
global variables and loops are a large number and can show complicated while your software grows to hundreds of thousands of lines of code (which maximum do!). they will impact code someplace else that is tough to figure, or motive noisy naming clashes. assume two times before you pollute the global namespace with variables, features, loops, and so forth.
In a super case, you ought to have no blocks defined globally. this is. all transfer statements, attempt-trap, foreach, whilst-loops, and so forth. have to be written inside a method or a feature. techniques have to be written internal elegance definitions, and sophistication and function definitions ought to be within namespaces.
2.) Use significant Names & Conventions
never use names like $ok, $m, and $check on your variables. How do assume to read such code within the future? precise code should be significant in terms of variable names, function/approach names, and sophistication names. a few suitable examples of meaningful names are: $request, $dbResult, and $tempFile (depending on your coding fashion recommendations these may also use underscores, camelCase, or PascalCase).
3.) Use meaningful systems
4. Use version manipulation software
inside the antique days, desirable improvement teams relied on CVS and diff patches for version manipulate. in recent times, though, we have a variety of answers available. dealing with changes and revisions must be easy but powerful, so choose some thing model control software program with the intention to paintings pleasant with the workflow of your improvement group. I decide upon using a allotted version manipulate tool like Git or Mercurial; each are free software/open source and really powerful.
A Few “GreyHound” Tips To Make Coding As A Beginner Easier
It was tough when I first learned coding as a beginner. Java was my first language I believe and it was difficult. But looking back I’d give myself these 3 tips when first starting off learning to code online:
1. Use a Coding Directive/Standard
It’s smooth to write horrific, unorganized code, but it’s difficult to maintain such code. true code normally follows a few general for naming conventions, formatting, etc. Such standards are first-rate because they make matters deterministic to folks that read your code afterwards, which includes yourself.
you can create your personal coding popular, however it’s higher to stick to at least one with wider-popularity. Publicly maintained standards like Zend Framework Coding trendy or quickly to be PSR-1 Coding style guide rather, it’ll be simpler for others to conform.
2. Use Comments!
feedback are important. You received’t admire them till you leave your thousand-line script for more than one days and return to and try to make sense of it. useful feedback make existence easier for yourself and those once you who have to maintain your code.
Write meaningful, single line feedback for indistinct traces; write full parameter and capability descriptions for capabilities and methods; for difficult logic blocks, describe the good judgment in phrases earlier than it if necessary. And don’t overlook, constantly hold your remarks up to date!
3.) Use Condensed Functions and REFACTOR
Code refactoring is the eighth dependancy of distinctly effective developers. agree with it or not, you ought to be refactoring your code on a day by day bases or your code isn’t in exact fitness! Refactoring keeps your code healthful, however what need to you refactor and how?
You have to be refactoring the entirety, from your architecture on your strategies and features, variables names, the range of arguments a method receives, and so forth.
how to refactor is more of an art extra than a science, however there are some policies of thumb that may shed a few mild on it:
-In case your characteristic or approach is greater than 20-25 lines, it’s much more likely which you are together with an excessive amount of common sense inner it, and you may probable break up it into two or greater smaller capabilities/methods.
-If your technique/feature call is extra than 20 characters, you ought to both reconsider the call, or rethink the whole characteristic/approach via reviewing the first rule.
-When you have a number of nested loops then you’ll be performing some aid-extensive processing with out figuring out it. In fashionable, you must reconsider the logic if you are nesting extra than 2 loops. three nested loops is just horrible!
-Remember if there are any applicable design styles your code can follow. You shouldn’t use patterns just for the sake of the use of styles, however styles provide tried-and-true ready-concept answers that might be relevant.
These are great tips I wish I had told myself when I first learned how to code java online!
