Compile a simple Java program
javac Example.java # generate Example.class; bytecode version of the program java Example # run bytecode in Java Virtual Machine
Get a hello world program from http://docs.oracle.com/javase/tutorial/getStarted/cupojava/unix.html.
Swing
Hello World Example
For example, create a new subdirectory 'start' and put HelloWorldSwing.java there. Then we can build and run the swing program by
javac start/HelloWorldSwing.java # Or javac HelloWorldSwing.java if we are in start directory java start.HelloWorldSwing
Quit Button Example
Note that it is necessary to create the directory com/zetcode according to package statement in java code. Also the filename must be consistent with the class name.
mkdir com mkdir com/zetcode nano com/zetcode/QuitButtonExample.java javac com/zetcode/QuitButtonExample.java java com/zetcode/QuitButtonExample
