For developing mobile application, you can learn java for android app development and it’s accepted unanimously as the best programming language.

It is an object- oriented language developed by James Gosling Sun Microsystem in 1995 before the company was acquired by Oracle corporation; and became the most prominent language for programming within 20 years of its usage.

Java is best know for features such as portability, simplicity, being secure, platform independent, robust, distributed, object-oriented, interpreted and architecture neutral amongst others and thinking of what java is used for, it’s used in coding programs for industrial purposes, used in developing apps that run on different OS such as Linux, Windows and even Mac and in mainframe computers

It’s not only that it has much importance and it’s widely uses but also has some advantages of over other programming languages, possibly that’s more reasons people want to learn more about it and use it in developing not only android apps iPhone apps and others.

Java is no doubt one of the best and most valuable programming languages and rank in top 10 in almost every field where programming is employed; it’s one of the best to learn easily as a beginner, learning for getting jobs and developing game app.

It’s also one of the most demanding programming language in software companies and for high payment when you’re hired and will surely be relevant in the future of programming languages.

In the PYPL Popularity of Programming Languages Index, java rank first as the most programming language people want to learn, with more searches about java tutorials and online courses; also it ranks first the TIOBE Programming Community Index and android OS has the most apps developed on her platform.

If you want to learn java easily as a beginner with no programming experience, there’s no best way to learn it rather than reading java programming books, joining some coding learning sites like codeacademy, W3school etc, taking online courses and tutorials, and practising anything you learn.

There are coding assignments online, from simple to complex and you can attempt to solving these tasks posted by others.

How JAVA language works?

In other coding or programming language, the code is first translated by a compiler into instructions, while in JAVA instead turns code into Bytecode by Java Virtual Machine (JVM) compiler(Javac) irrespective of the computer architecture which is then interpreted by software JRE (Java Runtime Environment) and run on this JVM

Why Java the best programming language?

Java is easy to learn, the language has fluent English like syntax and less mysterious character and there are more resources available online free to help in learniythe language
Java has rich API, xml parsing, database connection, networking, utilities and provides almost everything that developers expect
It is an open source and available FREE
Eclipse and Netbeans are the powerful tools that brings life to JAVA script
There are much job opportunities for java programmers anywhere in the world.
Java is widely used and broadly used on different platforms, mobile, desktop and higher applications; stable and scalable.
There are many java programmers in the world, making problem solving easier for beginners and other developers since you have great communities of developers to help you with any task.

Interaction of JAVA and Android Phones

Android have succeeded to keep JAVA on the forefront in last couple of years. JAVA gives the best option for development of mobile application that is based on android, as android consist of its own API’s and JAVA libraries.

So, for Android Application, you use android API’s as well as JAVA to write code for Android apps.These apps are called as native apps, as it is developed by using native tools and libraries.

You can also code in other language as well but you need a framework to convert into native app for that API. To execute the programming files, Android does not use JVM (JAVA Virtual Machine) but instead uses DVM (Dalvik Virtual Machine), Which is not a true JVM.

So, to execute the files, it has to convert into DEX format and then bundled into Android Package (APK).

For mobile application, JAVA has specially designed J2ME (JAVA to micro edition). All J2ME application must have main class that is derived from a special class called MIDlet.

The standard JAVA runtime environment for these devices is provided using (MIDP) Mobile Information Device Profile and Connected Limited Device Configuration (CLDC).

To write J2ME applications, you need the JAVA platform micro edition SDK (software development kit) and IDE, which can be Eclipse or Netbeans.

But to develop Android application, JAVAmidlet has to convert into Android apps and for that, tools like J2Android is used. This tool can convert any JAVA midletinto Android apps.

There is a question raised on the JAVA performance and future application but java gives the platform to promising language based on JVM such as Scala and Clojure and with the introduction of new versions like Java 7 and Java 8 161 CPU update last month, it will become more efficient.
