Introduction of JAVA
Java is an object-oriented programming language that produces software for multiple platforms.
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.
How it Works ?
Java code is compiled into JVM (Java virtual machine) bytecode, the bytecode then runs according to the JVM. The JVM then passes the actual processing work to the processor in its own language.
Source Code ➡️ Byte Code ➡️ Machine Code
