I created a JPanel Form and I want to set a value to some TextFields.

(我创建了一个JPanel表单，我想为某些TextFields设置一个值。)

I created in the design window of netbeans the textfields that I need, but in the source windown I don't know how to add text to those textFields that I created.

(我在netbeans的设计窗口中创建了我需要的文本字段，但是在源窗口中，我不知道如何向我创建的那些textField中添加文本。)

The only thing that I know is that I have to use setText method, but I'm a bit lost and I don't know how to use it.

(我唯一知道的是必须使用setText方法，但是我有点迷茫，我不知道如何使用它。)
