What Are The Benefits of Learning Java

Java is the most widely used programming language in developing client-server applications, web-based applications, desktop applications, mobile applications etc. There are several benefits of learning java language.

1. Platform Independent

First and foremost benefit of learning Java is that it is platform independent, means a java program written in one computer can be run in any other computer without recompiling it because java compiler does not convert source code of java directly into machine code, rather it first converts it into bytecode, which is then converted by Java virtual machine (JVM) into machine code. So, that generated bytecode can be run in any computer regardless of environments, and this is also called portability (WORA) means write once run anywhere.

2. Easy To Learn

Java language is very easy to learn for professionals and also for beginners because its syntax is inherited from C and C++, so those who know basic of one of these languages can easily grasp java, and for beginners who don’t know any programming language, there are lots of books and video tutorials on the internet.

JavaDoc is the java documentation generator tool which provides complete documentation of java.

Any information related to Java features (classes, packages etc) can be found on the website of Oracle: http://www.oracle.com/technetwork/java/javase/documentation/index.html

3. Object-Oriented Language

Java is the object-oriented language. OOP (Object-Oriented Programming) is one of programming paradigms used to reduce the complexity of large programs and make the code modifiable and manageable. OOP features like Inheritance, Polymorphism and Encapsulation are used in different aspects. For example, inheritance is used to make the code reusable, polymorphism is used to make the code flexible and encapsulation is used for making the code protected from outside access.

4. Network-Centric Language

Java is most popular programming language for developing client-server and web-based applications because it provides rich APIs and frameworks like spring, hibernate, struts for developing network-centric applications. Most popular social networking websites used java language including Twitter, Linkedin, Amazon, and eBay etc.

5. Java Has Many Versions

Java language consists of several versions like J2SE (Standalone Edition) used to develop desktop applications and applets, J2EE (Enterprise Edition) used to develop network and web-based applications, and J2ME (Mobile Edition) used to develop mobile applications.

6. Rich Apis

Java provides rich APIs for developing applications in all platforms. For example, there are powerful frameworks like Swing and JavaFX used in developing large desktop applications, and Spring, Hibernate, Struts are used to developing network-based applications.

7. Development Tools

There are powerful development tools have been developed for java language like Eclipse, Netbeans, Gradle, and IntelliJ. These are automated IDEs (Integrated Development Environments), enable users to write and debug Java programs easily.

8. Security

Java provides security in several ways.

• Java programs are first converted into bytecode which is encrypted from outside access and can only be executed by java runtime environment (JRE).
• In Java, there is no direct access to memory like in C and C++, means java does not support pointers, that’s why Java programs are secure from memory access violations which are the root causes of bugs and other problems in most applications.
• Java provides access level specifiers such as private, public and protected, these are used to limit the access of data and code in the programs.

9. Performance

Because Java programs are first converted into bytecode then in machine code, so java programs were slow in its initial versions as compared to native languages like C and C++, but now just-in-time (JIT) compiler has been developed and it is a part of java virtual machine which speed-up the performance of Java programs at runtime.

10. Multithreading

Java provides built-in support for multithreading which is not supported by some languages like C++ or PHP. Multithreading is the technique in which we perform multiple tasks within a program at the same time by dividing the programs into multiple threads. Java provides rich APIs for making concurrent and parallel programs.

11. Android Adoption

Google has adopted the Java language in android development. Now it is mandatory for any programmer to learn java before starting android development.
