🌈🌈今天是六一，各位被选召的孩子们节日快乐。今天光子郎带大家用JAVA写几个简单的小游戏玩玩，用代码找回同心。废话少说，开整！

🚗🚗猜数字游戏
import java.util.Random;
import java.util.Scanner;
public class GuessNumberGame {
public static void main(String[] args) {
Random random = new Random();
int targetNumber = random.nextInt(100) + 1;
int guessCount = 0;
System.out.println("欢迎来到猜数字游戏！");
Scanner scanner = new Scanner(System.in);
while (true) {
System.out.print("请输入一个1到100之间的整数：");
int guess = scanner.nextInt();
guessCount++;
if (guess == targetNumber) {
System.out.println("恭喜你，猜对了！你总共猜了" + guessCount + "次。");
break;
} else if (guess < targetNumber) {
System.out.println("猜的数字太小了，请再试一次。");
} else {
System.out.println("猜的数字太大了，请再试一次。");
}
}
scanner.close();
}
}
这个游戏的规则很简单，程序会随机生成一个1到100之间的整数，玩家需要通过输入数字来猜测这个数是多少。程序会根据玩家猜测的数字给出提示，直到玩家猜对为止。在游戏结束时，程序会告诉玩家猜测的次数。

addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
int key = e.getKeyCode();
if (key == KeyEvent.VK_UP && snake.getDirection() != Direction.DOWN)

return x < 0 || x >= SnakeGame.WIDTH || y < 0 || y >= SnakeGame.HEIGHT;

}
这个贪吃蛇游戏使用Java的图形界面库（Swing）来实现，玩家通过控制方向键来控制蛇的移动，目标是吃到食物并避免碰到自己的身体或边界。当蛇的头部与身体或边界发生碰撞时，游戏结束。（如果你有兴趣，还可以尝试增加一些功能，比如计分系统、难度级别等等）
🎇🎇井字棋小游戏
import java.util.Scanner;
public class TicTacToeGame {
private char[][] board;
private char currentPlayer;
private boolean gameOver;
public TicTacToeGame() {
board = new char[3][3];
currentPlayer = 'X';
gameOver = false;
initializeBoard();
}
public void playGame() {
System.out.println("欢迎来到井字棋游戏！");
while (!gameOver) {
printBoard();
int[] move = getPlayerMove();
makeMove(move[0], move[1]);
if (checkWin()) {
printBoard();
System.out.println("玩家 " + currentPlayer + " 赢了！");
gameOver = true;
} else if (checkDraw()) {
printBoard();
System.out.println("平局！");
gameOver = true;
} else {
switchPlayer();
}
}
}
private void initializeBoard() {
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
board[i][j] = '-';
}
}
}
private void printBoard() {
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
System.out.print(board[i][j] + " ");
}
System.out.println();
}
}
private int[] getPlayerMove() {
Scanner scanner = new Scanner(System.in);
System.out.print("玩家 " + currentPlayer + "，请输入您的下一步坐标（行 列）：");
int row = scanner.nextInt();
int col = scanner.nextInt();
return new int[]{row, col};
}
private void makeMove(int row, int col) {
if (row >= 0 && row < 3 && col >= 0 && col < 3 && board[row][col] == '-') {
board[row][col] = currentPlayer;
} else {
System.out.println("无效的移动！请重新输入。");
int[] move = getPlayerMove();
makeMove(move[0], move[1]);
}
}
private boolean checkWin() {
for (int i = 0; i < 3; i++) {
if (board[i][0] == currentPlayer && board[i][1] == currentPlayer && board[i][2] == currentPlayer) {
return true;
}
if (board[0][i] == currentPlayer && board[1][i] == currentPlayer && board[2][i] == currentPlayer) {

return true;
}
return false;
}
private boolean checkDraw() {
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
if (board[i][j] == '-') {
return false;
}
}
}
return true;
}
private void switchPlayer() {
if (currentPlayer == 'X') {
currentPlayer = 'O';
} else {
currentPlayer = 'X';
}
}
public static void main(String[] args) {
TicTacToeGame game = new TicTacToeGame();
game.playGame();
}
}
经典的井字棋游戏，两位玩家轮流下棋，首先连成一条线的玩家获胜，如果棋盘填满且没有玩家获胜，则为平局。
👊👊石头、剪刀、布游戏
import java.util.Random;
import java.util.Scanner;
public class RockPaperScissorsGame {
public static void main(String[] args) {
String[] choices = { "石头", "剪刀", "布" };
Scanner scanner = new Scanner(System.in);
Random random = new Random();
System.out.println("欢迎来到石头、剪刀、布游戏！");
while (true) {
System.out.print("请输入你的选择（石头、剪刀、布）或输入 q 退出游戏：");
String playerChoice = scanner.nextLine();
if (playerChoice.equalsIgnoreCase("q")) {
break;
}
int randomIndex = random.nextInt(choices.length);
String computerChoice = choices[randomIndex];
System.out.println("你的选择：" + playerChoice);
System.out.println("电脑的选择：" + computerChoice);
String result = determineWinner(playerChoice, computerChoice);
System.out.println(result);
System.out.println();
}
System.out.println("游戏结束。谢谢你的参与！");
}
public static String determineWinner(String playerChoice, String computerChoice) {
if (playerChoice.equalsIgnoreCase(computerChoice)) {
return "平局！";
} else if (
(playerChoice.equalsIgnoreCase("石头") && computerChoice.equalsIgnoreCase("剪刀")) ||
(playerChoice.equalsIgnoreCase("剪刀") && computerChoice.equalsIgnoreCase("布")) ||
(playerChoice.equalsIgnoreCase("布") && computerChoice.equalsIgnoreCase("石头"))
) {
return "你赢了！";
} else {
return "电脑赢了！";
}
}
}
这个石头、剪刀、布游戏需要输入自己的选择（石头、剪刀、布），然后与电脑进行对战，决定胜负。游戏会根据规则判断出胜负，并展示结果。可以输入 "q" 退出游戏。
希望这几款小游戏能够让大家找回当初敲代码的初心，虽然是谋生手段，但是也不妨碍我们乐在其中。这个六一，希望大家能够开心敲代码，用代码找回童心~ ❤❤❤❤❤❤文章来源：https://www.toymoban.com/news/detail-467161.html
