JVM (Java Virtual Machine) is an abstract machine. It can also run those programs which are written in other languages and compiled to Java bytecode. JVMs are available for many hardware and software platforms. JVM, JRE, and JDK are platform dependent because the configuration of each OS is different from each other.

Is JVM platform dependent or independent What about JRE?

JVM, JRE and JDK are platform dependent because configuration of each OS differs. But, Java is platform independent. The Java Runtime Environment (JRE) is part of the Java Development Kit (JDK). It contains set of libraries and tools for developing java application.

Is java platform independent or dependent Why?

JDK is a software development kit whereas JRE is a software bundle that allows Java program to run, whereas JVM is an environment for executing bytecode. The full form of JDK is Java Development Kit, while the full form of JRE is Java Runtime Environment, while the full form of JVM is Java Virtual Machine.

What is the platform independent?

Is JDK required for JRE?

But the reality is JRE makes the java as platform independent and JRE is platform dependent. If we want to run the class file, we do not require JDK. Just JRE is sufficient to run the .class file.
