Java Platform Independent Language

Overview

The important feature of the Java programming language is platform independence. Java is referred to as a “platform-independent programming language” because it can run on different platforms without requiring modifications to the program source code.

Platform Independent Language

A platform is the environment in which the application runs. A platform is a combination of the operating system and the device hardware. Platform independence is different from Portability.

The portability feature allows programs written for a particular platform to run on other platforms with minimum changes.

JVM

Java code is compiled into bytecode, which is a platform-independent representation of the Java program. The bytecode is executed by the JVM(Java Virtual Machine), which is specific to each underlying target platform. As long as the JVM is installed on the target platform, the bytecode can be executed without any changes to the code.

WORA

This feature allows a Java application that is compiled on one platform to run on any other platform. This feature is also called as WORA(Write Once, Run Anywhere).

The principle of “Write Once, Run Anywhere” is key to Java’s platform independence. It means that you can write Java code on one platform (for example, on Windows) and run it on any other platform like Linux, macOS, etc without modification, as long as the JVM is available.

Java Incremental Operator

Java Incremental Operator In Java, the incremental operator( ++ )  is used to increase the value of a variable by 1. Java provides two types of incremental operators: Post-Increment: The value is used first, then it is incremented. For example: var++ Pre-Increment: The value is incremented first, then it is used. For example: ++var Example […]

Java Garbage Collection

Java Garbage Collection In Java, garbage collection is a process by which the Java Virtual Machine (JVM) automatically manages memory. In some languages, such as C++, dynamically allocated objects must be manually released by using the delete operator. What is Garbage Collection? Garbage collection (GC) is the process of identifying and disposing of objects that are […]
