First I created a JFrame and have added a JPanel. After that I set it as a Null Layout. Then added a label and set a background image for the frame. For my project I need to add separate 4 JPanels for this JFrame. On those JPanels I'm going to add Labels and Text boxes.

好的.您看到的大多数Java GUI都不是其他面板中的普通放置面板.

Sure. Most of the Java GUIs you see that are any more than trivial put panels inside other panels.

有时会使用其他面板来对通用控件或输出组件进行分组，并可能给它们加上标题边框.通常，使用不同的面板以便在GUI的不同部分中使用不同的布局管理器.这是一个著名的示例，它将布局的详细信息放在面板的标题边框中.

Sometimes a different panel is used to group common controls or output components and possibly give them a titled border. More commonly different panels are used in order to use different layout managers in separate parts of the GUI. Here is a well known example that puts the details of the layout in a titled border for the panel..
