WindowListener是接口吗？但是根据以下情况，实例化如何有效？我们不能实例化接口吧？

WindowListener l1=new WindowListener() {

        public void windowOpened(WindowEvent e) {
            // TODO Auto-generated method stub

        }

        public void windowIconified(WindowEvent e) {
            // TODO Auto-generated method stub

        }

        public void windowDeiconified(WindowEvent e) {
            // TODO Auto-generated method stub

        }

        public void windowDeactivated(WindowEvent e) {
            // TODO Auto-generated method stub

        }

        public void windowClosing(WindowEvent e) {
            // TODO Auto-generated method stub

        }

        public void windowClosed(WindowEvent e) {
            // TODO Auto-generated method stub

        }

        public void windowActivated(WindowEvent e) {
            // TODO Auto-generated method stub

        }
    };

这是创建一个实现 WindowListener 接口的新匿名类。
