Study Notes
Java Language
- Java is a high-level, object-oriented programming language.
Java Features

Java Virtual Machine (JVM)
- The JVM is responsible for executing Java bytecode, which is the intermediate representation of Java programs.
- It acts as a bridge between the program and the underlying hardware, enabling Java's platform independence.
Java Features (cont'd)
- Java is not dynamic, meaning it doesn't support runtime code modification like some other languages.
Main Method
