猜数字游戏java，要用到GUI图形界面，且运行要有次数限制测试效果如图
参考java代码和注释如下
import javax.swing.*;
import javax.swing.border.*;
import java.awt.*;
import java.awt.event.*;
public class GuessNumFrame extends JFrame {
private JPanel contentPane;
private int num;
private final JTextField jtfInput;
private final JLabel label;
static final int MAX_TIMES = 5; // 最多可以尝试5次
private int times = 0;// 记录尝试次数
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
GuessNumFrame frame = new GuessNumFrame();
frame.setVisible(true);// 窗口可见
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public GuessNumFrame() {
setTitle("猜数字");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(360, 160);// 窗口大小
setLocationRelativeTo(null);// 居中
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
setContentPane(contentPane);
JPanel panel_1 = new JPanel();
contentPane.add(panel_1, BorderLayout.CENTER);
panel_1.setLayout(new GridLayout(3, 1, 0, 0));
JPanel panel = new JPanel();
panel_1.add(panel);
JButton jbNum = new JButton("得到一个随机数");
panel.add(jbNum);
JPanel panel_2 = new JPanel();
panel_1.add(panel_2);
label = new JLabel("");
label.setOpaque(true);
label.setBackground(Color.CYAN);
panel_2.add(label);
JPanel panel_3 = new JPanel();
panel_1.add(panel_3);
jtfInput = new JTextField();
panel_3.add(jtfInput);
jtfInput.setColumns(10);
JButton jbOk = new JButton("确定");
jbOk.setEnabled(false);
panel_3.add(jbOk);
jbNum.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
num = (int) (Math.random() * 10);// 生成随即数
times = 0; // 猜测次数归零
label.setText("随机数已经生成范围0~9");
jtfInput.setText(null);// 输入框清空
jbOk.setEnabled(true);// 按钮恢复可用
System.out.println(num);
}
});
jbOk.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int x;
try {
x = Integer.parseInt(jtfInput.getText());// 取得输入框的数字 进行比较
} catch (Exception e1) {
JOptionPane.showMessageDialog(null, "输入格式错误!请输入数字", "提示", JOptionPane.WARNING_MESSAGE);
return;//输入字母等非整数,直接返回
}
if (x == num) {
JOptionPane.showMessageDialog(null, "厉害,猜对了~!");
jbOk.setEnabled(false);//按钮设置为不可用
return;//猜对了也返回
} else if (xnum) {
JOptionPane.showMessageDialog(null, "你猜小了", "提示", JOptionPane.WARNING_MESSAGE);
} else if (xnum) {
JOptionPane.showMessageDialog(null, "你猜大了", "提示", JOptionPane.WARNING_MESSAGE);
}
times;
if (times = MAX_TIMES) {
JOptionPane.showMessageDialog(null, "尝试次数过多失败", "提示", JOptionPane.WARNING_MESSAGE);
jbOk.setEnabled(false);//按钮设置为不可用
return;// 猜错次数太多也返回
}
}
});
}
}
用java编写一个猜字游戏程序，答案不限 。急?。。?/h2>public static void main(String[] args){
Random r = new Random();
Scanner sc = new Scanner(System.in);
//100以内
int num = r.nextInt(100);
System.out.println(num);
int gsNum=-1;
do{
System.out.println("请输入要猜的数字：");
gsNum = sc.nextInt();
if(numgsNum){
System.out.println("太小啦");
}else if(numgsNum){
System.out.println("太大啦");
}
}while(num!=gsNum);
System.out.println("正确");
}
用JAVA语言编写一个“猜数字游戏”的程序int num = (int)(Math.random()*100) 1;
Scanner sc = new Scanner(System.in);
int guessNum = -1;
while (guessNum != num) {
System.out.println("请输入1-100之间整数");
guessNum = sc.nextInt();
if (guessNum == num) {
System.out.println("中啦");
} elseif (guessNumnum) {
System.out.println("小啦");
} else {
System.out.println("大了");
}
}
扩展资料：
编写思路
1、成1-100之间随机数
(int)(Math.random()*100) 1;
提示用户输入数字 ，
Scannersc=new Scanner(System.in);
int guessNum = sc.nextInt();
需要将随机数和用户输入的数字进行比较 。
猜一次：
Scanner sc = new Scanner(System.in);
int num = (int)(Math.random()*100) 1;
System.out.println("请输入0-100之间整数");
int guessNum = sc.nextInt();
if (guessNum == num) {
System.out.println("中啦");
} elseif (guessNumnum) {
System.out.println("小啦");
} else {
System.out.println("大了");
}
二、使用while循环
publicstaticvoid main(String[] args) {
int num = (int)(Math.random()*100) 1;
Scanner sc = new Scanner(System.in);
while (true) {
System.out.println("请输入1-100之间整数");
int guessNum = sc.nextInt();
if (guessNum == num) {
System.out.println("中啦");
} elseif (guessNumnum) {
System.out.println("小啦");
} else {
System.out.println("大了");
}
}
}
三、最后用while() 括号中的条件表达式，当用户猜测的数和系统生成的数字不相等时，就需要继续循环 。
java猜数字游戏怎么怎么做到在游戏结束后输入y重新开始输入n退出游戏？下面是源代码while(true){
//你的程序
System.out.println("再玩一次？");
String st= scan.next();
if( st=="y")｛continue;｝
if( st=="n")｛break;｝
System.out.println("既不是y也不是n ， 出错");
}
