主要介绍了JAVA的基本知识和异常处理的知识

import java.io.*;

interface Weapon {  //声明武器interface
    public int Weapon_Missile=1;  //导弹常数声明
	public int Weapon_Machine_Gun=2;//机枪常数声明
	public void Attacking (int Equipment); //声明攻击method
}

class Car  {
    String CarName;   //车辆名字
}

class Plane  {
    String PlaneName;  //飞机名字
}

class Fighter  extends Plane implements Weapon  {  //战斗机类
     public Fighter(String n)  //声明构造函数
	   {
	     PlaneName=n;
	   }	   
	 public void Attacking(int Equipment) {//完成Attacking method
	     switch(Equipment) {
		   case Weapon_Missile:  System.out.println(PlaneName +"使用导弹攻击"); break;
		   case Weapon_Machine_Gun:  System.out.println(PlaneName +"使用机枪攻击"); break;
		 }
	}
}

class Tank extends Car implements Weapon  {  //坦克类
    public Tank(String n)   //声明构造函数
	  {
	      CarName=n;
	  }
	  //
	public void Attacking(int Equipment) {
	   switch(Equipment) {
		   case Weapon_Missile:  System.out.println(CarName +"使用导弹攻击"); break;
		   case Weapon_Machine_Gun:  System.out.println(CarName +"使用机枪攻击"); break;
		 }
	}
}

public class InerfaceSample {
	public static void main(String[] args) 
	{
		Fighter f=new Fighter("苏-30");//产生名为苏-30的战斗机对象
		Tank ta=new Tank("M1");//产生名为M1的坦克对象
		
		f.Attacking(f.Weapon_Missile);//调用f对象的Attacking method
		ta.Attacking(ta.Weapon_Machine_Gun);//ta对象Attacking method
	}
}


/*  输出结果：
苏-30使用导弹攻击
M1使用机枪攻击
*/
