我写了一个GUI程序来猜测1到200之间的随机数。当我运行它时,我无法正确执行它。我可以猜两次相同的数字,有时它会说“太低”,有时它会说“太高”。我必须要尝试一些我尝试过的故障,但我很遗憾为什么这不起作用。这是我的代码:
import java.util.Random;
public class GuessPanel extends javax.swing.JPanel {
protected Random random;
protected int x;
protected int n;
public GuessPanel() {
initComponents();
}
@SuppressWarnings("unchecked")

private void guessButtonActionPerformed(java.awt.event.ActionEvent evt) {
random = new Random();
String s = userField.getText();
int i = 200;
x = random.nextInt(i);
n = Integer.parseInt(s);
if (x == n)
{
answerLabel.setText("You guessed right!!!");
}
else if (x > n)
{
answerLabel.setText("Your guess is too low, guess again");
}
else if (x < n)
{
answerLabel.setText("Your guess is too high, guess again");
}
}
// Variables declaration - do not modify
private javax.swing.JLabel answerLabel;
private javax.swing.JButton guessButton;
private javax.swing.JLabel jLabel1;
private javax.swing.JTextField userField;
// End of variables declaration
}

每次按下“guess”按钮时,您都会生成一个新的随机数。加载GUI时要么这样做一次,要么创建一个新按钮来重置游戏并将随机数生成代码放在那里。
