java - Java:纸张，岩石，剪刀GUI

我的课已经分配了一个石头，纸，剪刀的游戏。这是作业说明：

学习目标 ：


练习使用枚举
创建一个包含构造函数，字段和方法的枚举
设计和实现自己的GUI
创建一个可运行的jar


描述：
编写程序在计算机上播放剪刀石头布

要求：


创建一个代表三个选项的枚举：石头，纸张和
剪刀。


包含ImageIcon类型的字段（可选地，更多字段）
包括一个构造函数
包括评估方法

创建一个可在计算机上播放Rock Paper Scissors的gui应用程序


允许用户选择三个选项之一。
用户做出选择后，计算机将随机选择
石头，纸或剪刀
对于这两个选择，将显示相应的图像
另外显示结果（谁击败了谁）
用户需要能够多次播放而无需重新启动
应用程序
创建一个包含源代码的可运行jar（4分）



*编辑

好的，我正处于困境中，大多数情况下真正需要的全部是validate（）方法。关于如何去做有什么想法吗？在过去的一个小时里，我一直在动脑筋，但我还不太清楚。无论如何，这是更新的代码：

import javax.swing.ImageIcon;

public enum RPSChoice {
    ROCK(new ImageIcon(RPSChoice.class.getResource("rock.png"))),
    PAPER(new ImageIcon(RPSChoice.class.getResource("paper.png"))),
    SCISSORS(new ImageIcon(RPSChoice.class.getResource("scissors.png")));

        private ImageIcon imgChoice;

        private RPSChoice(ImageIcon imgChoice) {
            this.imgChoice = imgChoice;
        }

        public ImageIcon getImageIcon(){
            return imgChoice;
        }

    public static void evaluate(){
        //TODO
    }

    public static RPSChoice randomChoice(){
        return values()[(int) (Math.random() * values().length)];
    }
}

和gui

            addButtons(choicePanel, scissors, btnScissors);
        }

            contentPane.add(humanDisplay, BorderLayout.WEST);
            humanDisplay.setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5));

            contentPane.add(computerDisplay, BorderLayout.EAST);

            winnerAnnouncement.setHorizontalAlignment(SwingConstants.CENTER);
            contentPane.add(winnerAnnouncement, BorderLayout.CENTER);

            lblComputer.setHorizontalAlignment(SwingConstants.CENTER);

            humOrCompPanel.add(lblComputer);

            return choicePanel;
        }

        private void addButtons(JPanel choicePanel, RPSChoice choice, JButton button ){
            button.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent arg0) {
                    humanDisplay.removeAll();
                    humanDisplay.add(new JLabel(choice.getImageIcon()));

                    computerDisplay.removeAll();
                    randChoice = RPSChoice.randomChoice();
                    computerDisplay.add(new JLabel(randChoice.getImageIcon()));

                    choicePanel.repaint();
                    choicePanel.revalidate();

                }
            });
            choicePanel.add(button);
        }
    }

谢谢大家到目前为止提供的所有帮助！

最佳答案

您可以向枚举添加变量ImageIcon，并将其图像与ROCK，PAPER，SCISSORS关联：

public enum RPSChoice {

    ROCK(new ImageIcon(RPSChoice.class.getResource("rock.png"))),
    PAPER(new ImageIcon(RPSChoice.class.getResource("paper.png"))),
    SCISSORS(new ImageIcon(RPSChoice.class.getResource("scissors.png")));

    ImageIcon img;

    private RPSChoice(ImageIcon img) {
        this.img = img;
    }

    public ImageIcon getImage() {
        return img;
    }

}
