1、创建捕手类
public class Test02_Capture{//定义类的属性变量String name; //名字int food; //饵料数量int food_out; //捕手丢出的饵料int cap_fish; //已经抓到的鱼数量//定义类的构造函数Test02_Capture(String name, int food, int food_out, int cap_fish){this.name = name;this.food = food;this.food_out = food_out;this.cap_fish = cap_fish;}//定义捕手方法：捕鱼（传入对象鱼）public void hook(Test02_Fish tf){System.out.println( this.name + "在开始捕捉" + tf.name + "~");this.food -= food_out; //饵料数量减少tf.fish_num -= this.food_out; //鱼的数量减少}}
2、创建鱼类
public class Test02_Fish{//定义类的属性变量String name; //名字int fish_num; //鱼数量int fish_out; //鱼逃出渔网的数量//定义类的构造函数public Test02_Fish(String name, int fish_num, int fish_out){this.name = name;this.fish_num = fish_num;this.fish_out = fish_out;}//定义鱼的方法：逃出渔网（传入对象捕手）public void escape(Test02_Capture tc){System.out.println(this.fish_out + "只" + this.name + "正在逃出" + tc.name+ "的渔网~");this.fish_num += fish_out; //鱼的数量增加tc.cap_fish += tc.food_out-fish_out; //捕手已经抓到的鱼数量=丢出的饵料-逃出的鱼System.out.println("已经抓到的鱼有：" + tc.cap_fish + "只。");System.out.println("鱼的数量还剩："+ this.fish_num + "只。");}}
3、创建用户类
public class Test02_Client{public static void main(String[] args){//第一轮捕鱼//创建捕手、鱼类的对象//初始一号捕手，饵料数量100，丢出饵料5， 已经捕到的鱼0Test02_Capture TC = new Test02_Capture("一号捕手", 100, 5, 0);//初始金枪鱼， 池塘鱼的数量500， 逃出渔网的鱼4Test02_Fish TF = new Test02_Fish("金枪鱼", 500, 4);System.out.println("------------------第一轮捕鱼--------------------");TC.hook(TF); //开始捕鱼，传入鱼类（鱼的数量）TF.escape(TC); //鱼逃渔网，传入捕手类（已经捕捉到的）//第二轮捕鱼//初始二号捕手，饵料数量100，丢出饵料30， 已经捕到的鱼1Test02_Capture TC2 = new Test02_Capture("二号捕手", 95, 30, 1);//初始红鲤鱼， 池塘鱼的数量499， 逃出渔网的鱼4Test02_Fish TF2 = new Test02_Fish("金枪鱼", 499, 2);System.out.println("------------------第二轮捕鱼--------------------");TC2.hook(TF2); //开始捕鱼，传入鱼类（鱼的数量）TF2.escape(TC2); //鱼逃渔网，传入捕手类（已经捕捉到的）}}
