Today, I will share with you a wave of Random, Scanner's java learning and practice. Made a small game that is bigger than the computer.
First, we create a file named compare_game.java, and then add the following code.
The complete code is as follows:
import java.util.Random;
import java.util.Scanner;
/**
* 这是一个与电脑比较数字大小的[0,100]小游戏
* @author Mr.Pan_学狂
* created time by 2021-2-27
*/
class compare_game{
public static void main(String[] args){
System.out.println("比大小游戏v1.0版");
System.out.println();
Scanner sc = new Scanner(System.in);//创建输入对象
Random random = new Random();//创建一个随机数对象
String yes = new String("是");//定义字符yes
String no = new String("否");//定义字符no
for(int i = 0;i < 20;i++) {
//循环20次
System.out.println("请输入数字:");
int number1 = sc.nextInt();//人输入的数字
int number2 = random.nextInt(101);//电脑生成的随机数
if(number1 < 0 | number1 > 100) {
//如果输入的数字大于100或者是小于0则出错
System.out.println("输入的数字超出范围!!");
break;
}
if(number1 > number2) {
System.out.println("电脑生成的随机数是"+number2);
//System.out.println("输入的数字是"+number1);
System.out.println("你获胜了!!");
System.out.println("是否继续游戏?");
String want = sc.next();
System.out.println();
if(want.equals(yes)) {
//判断输入的字符是否是"是"
continue;
}
else if(want.equals(no)) {
//判断输入的字符是否是"否"
System.out.println("退出游戏!!");
break;
}
else {
System.out.println("输入错误!!");
break;
}
}
else if(number1 < number2) {
System.out.println("电脑生成的随机数是"+number2);
System.out.println("电脑获胜了!!");
System.out.println("是否继续游戏?");
String want = sc.next();
System.out.println();
if(want.equals(yes)) {
//同理
continue;
}
else if(want.equals(no)){
//同理
System.out.println("退出游戏!!");
break;
}
else {
System.out.println("输入错误!!");
break;
}
}
else {
System.out.println("电脑生成的随机数是"+number2);
System.out.println("平局!!");
continue;
}
//System.out.println("生成的随机数是"+number2);
}
}
}
The results of the operation are as follows:
Finally, thank you all for coming to watch my article. There may be many improprieties in the article, and I hope to point out Hehaihan.
