Re: [問題] 如何寫成一個猜數字的遊戲

[monomorium (旅人的足跡)]

寫了一個可以用的 GUI ，不過有些小地方還需要修改

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.event.*;

class GuessNumber implements ActionListener {
  JFrame frame;
  JTextField input;
  JButton newgame, guess;
  JLabel result;
  ArrayList<JComponent> GUIComponent;
  String answer;

  public static void main(String[] args) {
    new GuessNumber();
  }

  public GuessNumber() {
    frame = new JFrame("Guess Number");
    frame.setSize(200, 100);
    frame.setLayout(new GridBagLayout());
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    input = new JTextField();
    newgame = new JButton("New Game");
    newgame.setActionCommand("new");
    newgame.addActionListener(this);
    guess = new JButton("Guess");
    guess.setActionCommand("guess");
    guess.addActionListener(this);
    result = new JLabel("0A0B");
    int att[][] = {{0, 0, 2, 1, 0, 0, 1, 10},

        result.setText("No answer!!");
      }
