- 特点：本质就是一个子类，并会立即创建出一个子类对象
public class Test {public static void main(String[] args) {//匿名内部类Animal a = new Animal(){@Overridepublic void cry() {System.out.println("狗汪汪汪的叫~");}};}
}abstract class Animal{public abstract void cry();}
public class Test {public static void main(String[] args) {
// Swimming s1 = new Swimming(){
// @Override
// public void swim() {
// System.out.println("狗游得很快");
// }
// };
// go(s1);go(new Swimming(){@Overridepublic void swim() {System.out.println("狗游得很快");}});//设计一个方法,可以接收Swimming接口的一切实现类对象进来参加游泳比赛public static void go(Swimming s){System.out.println("开始----------");s.swim();}}interface Swimming{void swim();}
public class Test {public static void main(String[] args) {//搞清楚匿名内部类在开发中的真实使用场景//GUI编程//1.创建窗口JFrame win = new JFrame("登录界面");JPanel panel = new JPanel();win.add(panel);JButton btn = new JButton("李科翰cnm");panel.add(btn);//给按钮绑定单击事件监听器btn.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {JOptionPane.showMessageDialog(win,"李科翰是sb");}});win.setSize(400,400);win.setLocationRelativeTo(null);win.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);win.setVisible(true);}
