注意:Lambda表达式并不是说能简化全部匿名内部类的写法,只能简化函数式接口的匿名内部类
public class Test {
public static void main(String[] args) {
// 目标:认识Lambda表达式
// Swimming s = new Swimming() {
// @Override
// public void swim() {
// System.out.println("游泳~~~");
// }
// };
// s.swim();
Swimming s = () ->{
System.out.println("游泳~~~");
};
s.swim();
}
}
interface Swimming{
void swim();
}
