推荐答案
您可以使用 CardLayout 代替使用 JFrames 在不同表单之间传递值，它将保留您在前一个表单中输入的数据.您所要做的就是创建一个 JFrameForm 并向其添加面板.

Instead of Using JFrames for passing values between different forms you can use CardLayout which will persist your data which you have entered in the previous form.
All you have to do is Create a JFrameForm and add panels to it.
