I have a question to Java. I hope you can answer me.

How can it be possible to instantiate an interface like this code below :

ActionListener al = new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
if (ae.getSource() == button1)
{

System.out.println("Button selected!");

}
else
if (ae.getSource() == text1)
{
String text2 = ((JTextField)ae.getSource()).getText();

String text3 = ae.getActionCommand();

System.out.println("Text from ActionEvent : " + text2);
System.out.println("Text from TextField : " + text3);

}
}
};

button1.addActionListener(al);

Thank You !

Part of the java specification. Read the docs 'Anonymous classes'.

Because you are defining the (anonymous) class that implements the interface
in the very same statement.
