Example analysis of how to implement number guessing game in Java

This article mainly introduces you to the number guessing game implemented in Java in detail. A number is randomly given until you guess the correct size. It has certain reference value. Interested friends can refer to it

java implements a number guessing game where a number is randomly given and the size is guessed until it is correct

package com.swift;

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

public class GuessBigSmall {

  public static void main(String[] args) {
    Scanner scan=new Scanner(System.in);
    Random random = new Random();
    int number = random.nextInt(1000) + 1;
    for (;;) {
      System.out.println("请输入猜的——正整数——数字：");
      int guessNumber=scan.nextInt();
      if (guessNumber>number) {
        System.out.println("猜大了。");
        continue;
      } else if (guessNumber<number) {
        System.out.println("猜小了。");
        continue;
      } else {
        System.out.println("恭喜，猜对了。");
        break;
      } 
    }
  }
}

Another way to generate random numbers

package com.swift;

import java.util.Scanner;

public class GuessBigSmall2 {

  public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    int number = (int) (Math.random() * 1000 + 1);
    for (;;) {
      System.out.println("请输入猜的——正整数——数字：");
      int guessNumber = scan.nextInt();
      if (guessNumber > number) {
        System.out.println("猜大了。");
        continue;
      } else if (guessNumber < number) {
        System.out.println("猜小了。");
        continue;
      } else {
        System.out.println("恭喜，猜对了。");
        break;
      }
    }
  }
}
