What are you really looking for? The source code: it's in a file named src.zip, in your jdk folder.The API: http://java.sun.com/javase/6/docs/api/

JOptionPane is a class. It's in a .class file. I imagine the .class file is bundled up in a jar with a directory path corresponding to the package path.
