Random随机数和for循环，实现猜数游戏和双色球

package cn.wzt;

import java.util.Random;
import java.util.Scanner;

public class Csyx {
    public static void main(String[] args) {
        Random random = new Random();
        Scanner scanner = new Scanner(System.in);
        int sj= random.nextInt(100)+1;
        int i=0;
        while (true){
            if(i>9){
                System.out.println("你的次数已用光，成绩0分");
                break;
            }
            System.out.println("请输入1-100数值：");
            if (!scanner.hasNextInt()){
                if(scanner.nextLine().equals("exit")){
                    System.out.println("已成功退出游戏");
                    break;
                }else {
                    System.out.println("输入错误，请输入数值");
                    continue;
                }
            }
            int cs= scanner.nextInt();
            if(cs>sj){
                System.out.println("猜大了");
                ++i;
                continue;
            }else{
                if (cs 
2、双色球Ssq.java 
package cn.wzt;

import java.util.HashSet;
import java.util.Random;
import java.util.Set;

public class Ssq {
    public static void main(String[] args) {
        Random random = new Random();
        int blue= random.nextInt(16)+1;
        Set red=new HashSet();
        while (red.size()!=6){
            red.add(random.nextInt(33)+1);
        }
        System.out.print("红色：");
        for (int i:red){
            System.out.printf("%d ", i);
        }
        System.out.printf("t蓝色：%2d", blue);

    }
