Java mainly has two types of programs: Application and applet ).

Environment Settings: Standard Search Path = C:/j2sdk/bIn Class path classpath =.; C/j2sdk/lib

Five phases of Java program: 1) Editing: writing program, saved on Hard Disk

2) Compile: Use the compiler to translate the source program into bytecodes statements (javac filename. Java, generate the class file Java Virtual Machine language)

3) load: Call bytecodes to the memory (Java filename; appletviewer file.html)

4) Check: Check whether bytecodes is valid

5) Execution: The interpreter translates bytecodes into machine language for execution.
