• Familiar
• Object-oriented
• Robust
• Secure
• Architecture-neutral
• Portable
• High performance
• Interpreted
• Multithreaded
• Dynamic
• Distributed

In the execution of Java programming language, we use Java Virtual Machine (JVM). For the execution of byte code which is a highly optimized set of instructions designed to be executed by JVM. JVM is an interpreter for byte code.
