Study Notes

Java Platforms

Java's unique platform is based on its architecture, specifically its bytecode.
Java consists of three key components: JDK, JRE, and JVM.
JDK (Java Development Kit) combines JRE and developer libraries.
JRE (Java Runtime Environment) includes JVM and runtime libraries.
JVM (Java Virtual Machine) translates bytecode to machine code; it's platform-dependent.

Bytecode

Bytecode is created when Java source code is compiled.
Bytecode files have a ".class" extension.
Bytecode can easily be moved between different platforms without modification.
Bytecode can also be packaged in a Java Archive (JAR).
