您好,我是一名高中水平的新程序员,因此我对编程知之甚少,并且遇到了一些已经解决的错误,而其他一些我完全不理解.我将制作一个简单的Check Box选择程序,用户可以在各种选择之间进行选择,并根据其动作改变图像.程序本身编译得很完美,但是当我运行它时,它给了我一些复杂性.这是我的计划:

    sportshatButton.setMnemonic(KeyEvent.VK_W);


    santahatButton = new JCheckBox("Santa hat");
    santahatButton.setMnemonic(KeyEvent.VK_E);

    redshirtButton.setMnemonic(KeyEvent.VK_R);


    brownshirtButton = new JCheckBox("Brown Shirt"); …
