13 1. Java Basic • JAVA source code is first written in plain text files ending with the .java extension. • Those source files are then compiled into .class files by the Java compiler (javac). – A .class file does not contain code that is native to your processor; – it instead contains bytecodes(字节码) -- the machine language of the Java Virtual Machine. • The Java launcher tool (java) then runs your application with an instance of the Java Virtual Machine
