Java中关于使用接口来实现所有课程设计

package SeniorJava.Interface; public class ExtendsVsInterface { public static void main(String[] args) { littleMoney wukong = new littleMoney("悟空"); wukong.Climbing(); wukong.flying(); wukong.swimming(); } } class Money { private String name; public Money(String name) { this.name = name; } public String getName() { return name; } public void setName(String name) { this.name = name; } public void Climbing() { System.out.println(name+"会爬树"); } } interface flying { void flying(); } interface swimming { void swimming(); } class littleMoney extends Money implements flying,swimming { public littleMoney(String name) { super(name); } @Override public void flying() { System.out.println(getName()+"通过学习，最后学会了飞翔"); } @Override public void swimming() { System.out.println(getName()+"通过学习，最后学会了游泳"); } }
