问题

我尝试创建一个具有以下布局的JFrame：期望效果
而我目前拥有的是这个：当前进展。如何在两个图像之间以及顶部和底部创建填充？我尝试使用空边框属性并设置左边和右边的值，但中间、顶部和底部的空白空间没有被创建。

英文:

I am trying to create a JFrame that has a layout like this image desired goal
and what I currently have is this current progress. How do I create padding between the two images as well as at the top and bottom? I have tried using the empty border property and setting the left and right at their respective values, but the gap of space in the middle, top, and bottom does not get created.
