簡單的類實現接口的方法

public interface carepet {
	public void food();
	public void play();
}


public class Worker implements carepet{
	String name;
	public Worker(String name){
		this.name=name;
	}
	public void food(){
		System.out.println("這個叫"+name+"的工人是這樣喂他的寵物的");
	}
	public void play(){
		System.out.println("這個叫"+name+"的工人是這樣和它的寵物玩的");
	}
}

public class farmer implements carepet{
	int age;
	String name;
	public farmer(int age,String name){
		this.age=age;
		this.name=name;
	}
	public void food(){
		System.out.println("這個叫"+name+"的"+age+"的農民是這樣喂他的寵物的");
	}
	public void play(){
		System.out.println("這個叫"+name+"的"+age+"的農民是這樣和它的寵物玩的");
	}
}

public class StateLeader implements carepet{

this.job=job;

}

public void food(){

}

}

}
