Explanation for the java code?

Question

What does this code mean:

table = new JTable(){
        public boolean isCellEditable(int arg0, int arg1) {
            return true;
        }
    };

Answer 1

It's an anonymous class, which in this case has provided an implementation for JTable's isCellEditable method that always returns true.

Answer 2

Think of it as:

class MyJTable extends JTable
{
    public boolean isCellEditable(int arg0, int arg1) {
        return true;
    }
}
table = new MyJTable;
