Creating Games with Java: A Fun Introduction for Beginners

Introduction

Java is a powerful programming language that can be used to create a variety of applications Programs and Games. For beginners, it is a good choice to learn programming and game development. This article will guide you through creating a simple game using Java, introducing basic concepts and techniques step by step.

Practical Case: Number Guessing Game

We will create a simple number guessing game. Players need to guess a random computer-generated number, with hints provided for each guess until the player guesses correctly.

Step 1: Set up the game interface

Create a class named GuessNumberGame which will contain the game logic.

import java.util.Scanner;

public class GuessNumberGame {

    private static final int MAX_NUMBER = 100;
    private static final Scanner scanner = new Scanner(System.in);

    // 游戏的主方法
    public static void main(String[] args) {
        // 1. 生成一个随机数
        int randomNumber = generateRandomNumber();

        // 2. 循环获取用户的猜测
        while (true) {
            // 提示用户输入猜测
            System.out.print("请输入您的猜测（1-100）：");
            int guess = scanner.nextInt();

            // 3. 检查猜测是否正确
            if (guess == randomNumber) {
                System.out.println("恭喜！您猜对了！");
                break;
            } else if (guess < randomNumber) {
                System.out.println("您的猜测太小了，请再次尝试。");
            } else {
                System.out.println("您的猜测太大了，请再次尝试。");
            }
        }
    }

    // 生成一个指定范围内的随机数
    private static int generateRandomNumber() {
        return (int) (Math.random() * MAX_NUMBER) + 1;
    }
}

Step 2: Get user input

Use the Scanner class to get input from the user.

int guess = scanner.nextInt();

Step 3: Check Guesses

Compare the player’s guess to a random number. If the guess is correct, print a message and exit the loop. If the guess is wrong, a hint is provided based on whether the guess is greater or less than the random number.

if (guess == randomNumber) {
    System.out.println("恭喜！您猜对了！");
    break;
} else if (guess < randomNumber) {
    System.out.println("您的猜测太小了，请再次尝试。");
} else {
    System.out.println("您的猜测太大了，请再次尝试。");
}

Conclusion

Through this simple example, you have understood the following basic concepts of creating games in Java:

• Generate random numbers
• Get user input
• Check guesses using conditional statements
• Create and run a class in Java
