JVM: (Java Virtual Machine)

  • Java Virtual Machine plays the central role in this concept.
  • Each operating system has their own JVM, when output they produce after execution of bytecode is same across all operating systems.
  • javac compiler of JDK compiles the java source code into bytecode so that it can be executed by JVM.
  • JVM executes the bytecode generated by compiler.
  • Java byte codes can be thought of as the machine language of the JVM.
  • Java was designed with a concept of ‘write once and run everywhere.
  • That is why we call java as platform independent language
