1. Programmer codes Java source statements
2. Java compiler converts source statements into bytecode (platform-independent object language)
3. Bytecode is copied to the target platform
To execute a Java program
1. Platform-dependent Java Virtual Machine (JVM) software must be installed
2. A copy of the JVM is started
3. Each bytecode statement is interpreted (translated) by the JVM into platform-dependent machine language and executed under JVM control.
