java swing如何设计一个程序窗口的标题栏，还有右上角的三个按钮

Answer 1

import javax.swing.JOptionPane;

public class Test {

static int answer, x, y, score = 0;

static String generate() {
x = (int) (Math.random() * 100);
y = (int) (Math.random() * 100);
answer = x + y;
return "请问" + x + "+" + y + "=？";
}

public static void main(String[] args) {
JOptionPane.showMessageDialog(null, "现在开始测试，总共一百题！");
for (int i = 0; i < 100; i++) {
String tmp = JOptionPane.showInputDialog(generate());
if (tmp == null) break;
try {
if (Integer.parseInt(tmp) == answer) {
score++;
JOptionPane.showMessageDialog(null, "恭喜答对，进入下一步！");
} else {
JOptionPane.showMessageDialog(null, "错！");
}
} catch (NumberFormatException nfe) {
JOptionPane.showMessageDialog(null, "请输入数字！");
i--;
continue;
}
}
JOptionPane.showMessageDialog(null, "测试结束，你的分数是：" + score);
}
}

不用对话框的话，代码会长得多，所以你确定？

你是想在标题栏里输入标题吧,在属性里有一项标题可以设置.
