Java GUI 窗口会在启动时冻结
问题描述 投票：0回答：1
这是一个洗车的 GUI 程序。包含两个类演示和总计，计算后将在新窗口中显示总计。一切工作正常，决定再运行一次以提交屏幕截图，但它卡住了，就像程序正在运行但窗口冻结一样。我正在使用 Net bean 拖放方法。

在您正在使用的
initComponentssetEnabled(false)只需删除此行即可修复此问题。
哪里可以找到
/* Rest of your code */
jRadioButton2.setText("jRadioButton2");
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("Auto Tech and Mech Services");
setEnabled(false); //Line causing this issue
jLabel1.setText("Welcome to Auto Tech and Mech Services");
