1、新建一个自定义接口AnimalActionpublic interface AnimalAction { void fly(); void say(); void eat();}
3、鼠标光标放到AnimalActionImpl类名上，按下键盘Alt+Enter组合键，（在idea环境下）,在弹出框中选择implements methods
5、大功告成!public class Animal钽吟篑瑜ActionImpl implements AnimalAction { @Override public void fly() { } @Override public void say() { } @Override public void eat() { }}
