What is the logic behind calls like JOptionPane.method()

[Raghavan Chockalingam]

Forgive me on the title...here is the problem...
1. I need a clarification on what is the logic behind making calls like
JOptionPane.showMessageDialog();
Integer.parseInt();
We do not create objects for these variables and we call the methods of the classes directly...how this is possible...are they any special kind of classes???

2. I have not seen this kind of coding in any other language,,,can anyone explain me how this coding construct works???

 
menuItem.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
System.out.println("You have opted to exit the application now!!!");
System.exit(1);
}
});

They are static methods.

And regarding your second question, you should read about "anonymous inner classes".

to elaborate on 1: The static method creates its own frame, from which it gets input, and then returns that input. You never talk directly to the frame object
