What is platform-independent in Java?

Java Platform Independent

In this blog, we will discuss platform-independent in Java. JVM is platform-dependent. Java compiled code is platform-independent, which means it can run on any operating system. To be understood by the machine, the source code must be written in a machine-readable language, typically a machine-level language. 

The compiler converts the high-level language into a machine-readable format. As a result, a compiler is a program that converts source code from a programming language into executable code.

 In Java, this medium-term is known as the Java Byte Code. To learn and gain knowledge about Java, enrol in Java Training in Kolkata at FITA Academy.

Java Program Execution Step by Step:

  • When a program is written in JAVA, it is compiled by javac.
  • The JAVA compiler creates an a.class file or Bytecode instead of machine native code (unlike the C compiler).
  • The generated Bytecode is non-executable and requires an interpreter to run on a machine. The JVM is this interpreter, and thus the Bytecode is executed by the JVM.
  • Finally, the program manages to produce the desired result.

JVM is platform dependent

The vital element to reflect about Java is that the JVM is dependent on the operating system. So if you’re using Mac OS X, you’ll have a different JVM than if you’re using Windows or another OS. 

This point may be confirmed by trying to download the JVM for your machine — you will be presented with a list of JVMs about various operating systems, from which you will choose the JVM that corresponds to the operating system you are using. As a result, we can determine that the JVM is platform-dependent, telling that Java could become Platform-independent.

Points to Remember
  • Java’s platform independence is due to the Bytecode magic.
  • Java contributes to portability, a vital element of the JAVA language. The Java Development Kit (JDK) is installed in every system is installed in JVM. 
  • There is a JVM for each operating system that can read.class files or byte code.
  • The JVM is platform-dependent, despite JAVA being a platform-independent language. JVMs are planned for various operating systems, and byte code can run on types of platforms.

Conclusion

As we have enhanced the Java Platform Independence in Java, JVM is platform-dependent, and it’s essential. Java guides fresh programmers on thinking like a programmer, going through methods using logic and placing ideas to the test. In Computer Science curricula, Java is often the guiding language.
