Question

我想制作一个非常简单的hangman程序，其GUI使用6个图像来显示游戏的进展。我想硬编码“Hello”这个词，并且每个错误都会让用户改变图像。（共6张渐进式图像）。

我已经设法在Netbeans上使用Swing库制作GUI，但我对如何继续实际代码感到难过。有什么指针吗？

首先，您需要从背景代码开始，而不是可见部分。

例如，您可以创建一个名为Hangman的类，它为您提供了一种更改进度的方法（添加错误），以及一个为您提供当前绘制状态图像的方法。

伪代码如：

public class Hangman
{
    private int mistakesDone;

    private HashMap<Integer, Image> progressImages;

    public Hangman()
    {
        mistakesDone = 0;
        progressImages = new HashMap<Integer, Image>();

        for(int i = 0; i < 7;i++)
            progressImages.put(i, new ImageIcon(new URL("hangman_" + i)).getImage());
    }

    public Image getCurrentImage()
    {
        return proressImages.get(mistakesDone);
    }

    public void mistakeDone()
    {
        mistakesDone++;
    }

    public int getMistakesDone()
    {
        return mistakesDone;
    }

    public void resetMistakes()
    {
        mistakesDone = 0;
    }
}

现在您已经获得了Hangman类，您需要在Main-Game-Class中创建一个Object对象，或者您可以调用它。想要绘制时，可以让对象获取当前图像。记得更新错误完成！

我建议你也要对猜测部分的基本代码做同样的事情！（Outsourcsing在面向对象语言中是一件非常好的事情）
