This article is about how to use java to implement a simple number guessing game. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The details are as follows

1. Game Analysis:

The first step of the game: need a random number, and the random number has a range; (java's package has a Random class that can generate random numbers, and you need to import this package, as follows) the second step of the game: the design of guessing numbers, the number of guesses is 5 times.

two。 Programming implementation:

Import java.util.Random;import java.util.Scanner;public class Guess_num {public static void main (String [] args) {System.out.println ("Welcome to the guessing game!") ; System.out.println ("Please enter a number: (range is 0100)"); Random pc_game = new Random (); int pc_num = pc_game.nextInt (101); / / randomly generate an integer less than 101s Scanner input = new Scanner (System.in); int count = 5 while / guesses, customizable while (count > 0) {System.out.println ("you have a" + count+ "chance!") ; count--; System.out.print ("Please enter guessed numbers:->"); int user_num = input.nextInt (); if (pc_num = = user_num) {System.out.println ("you are right!"); count = 0;} else if (pc_num > user_num) {System.out.println ("sorry, guess small!");} else if (pc_num < user_num) {System.out.println ("sorry, guess big!") }} System.out.println ("Game over!") ; input.close ();}}
