Java Applications
All Java programs are written into a file with a ".java" extension.
Applications are .java files with a main method which is excuted first.
How to compile and run a Java application (via bytecodes):
- Run the compiler on a .java file:
- javac MyProgram.java
- producing a file "MyProgram.class" of Java bytecodes
- Run the interpreter on a .class file:
- java MyProgram
- which executes the bytecodes
