我使用netbeans。我做了一个由老师引起注意的java项目。一切都好。但问题是当我最大化该应用程序然后所有文本字段，标签，按钮的大小受到干扰，意味着它们不像我在netbeans中做的那样正确。尺寸自动变化。请帮助
它是一个netbeans项目......请参阅代码

使用GridBagLayout它会在您调整窗口大小时自动调整组件大小
检查this以获取帮助

您可能想要在窗口中添加LayoutManager。 NetBeans支持它。在NetBeans中右键单击窗口内部，悬停“设置布局”并选择正确的LayoutManager。
我总是使用GridBagLayout。这是一个教程：http://docs.oracle.com/javase/tutorial/uiswing/layout/gridbag.html
祝你好运。
