接的方法：

public class Calculator { }

int num1; int num2;

public void add(){ System.out.print(num1+\＋\}

public void minus(){ System.out.print(num1+\}

public void multiple(){

System.out.println(num1+\\}

public void divide(){ }

double x=num1/num2; int c=num1%num2;

System.out.println(num1+\\System.out.println(\余为：\

计算平均分和总成绩 import java.util.*;

public class ScoreCalc { int java; int c; int db;

public int calcTotalScore(){ int total=java+c+db; }

int avg=(java+c+db)/3; return avg;

public int calcAvg(){

加密：

public static void main(String[] args) { Scanner input=new Scanner(System.in);

int num; int rnum;

int[] number=new int[8];

System.out.println(\请输入一个不大于8位的整数\Scanner input=new Scanner(System.in); System.out.println(\请输入JAVA成绩\ScoreCalc scoreCalc =new ScoreCalc (); scoreCalc.java=input.nextInt(); System.out.println(\请输入分数\scoreCalc.c=input.nextInt();

System.out.println(\请输入分数\scoreCalc.db=input.nextInt(); scoreCalc.showTotalScore(); scoreCalc.showAvg();

num=input.nextInt(); int k=0; int i=0;

while(num>0){ number[i]=num;

i++;

num=num/10;

k=i;

continue; }

System.out.print(\反转：\for (i = 0; i < k; i++) {

课后本章作业2.5：竞猜活动，活动规则是：随机出现一个商品名，用户猜它的价值，如果在规定的次数内猜对，便可获得此商品。模拟竞猜活动。

import java.util.*;

public class QuessMachine {

int num=(int)(Math.random()*10%3+1); Scanner input=new Scanner(System.in); int maney; int zmaney;

public void showInfor(){ switch(num){

case 1: zmaney=5000000; System.out.println(\请猜宝马汽车的价格\

maney=input.nextInt(); guess();

} }

System.out.print(number[i]);

break; case 2:

zmaney=5000;

System.out.println(\请猜电动车的价格\maney=input.nextInt(); guess(); break;

zmaney=500;

System.out.println(\请猜玩具赛车的价格\maney=input.nextInt(); guess();

case 3:

break;

} }

public void guess(){

int i;

if(zmaney>maney){ System.out.println(\小了点！！\

maney=input.nextInt();

for (i = 0; i < 3; i++) {

continue; }else if(zmaney

if(i==3){ System.out.println(\次没有猜对！！！下次再来吧！！\} }

public static void main(String[] args) { QuessMachine a=new QuessMachine(); } }

**********第十二章（指导学习：人机猜拳游戏）**************

1.创建电脑类和玩家类，并且定义属性和方法： ******电脑类：

public class Computer { String name; //电脑对象名

int point; //电脑积分 a.showInfor();

continue;

}else{ System.out.println(\猜对了！！你牛！\ }

break;
