解决方案
解决方案二：
css
解决方案三：
setLayout(null);//布局为空的时候，小学习项目的话。根据自己的喜好，想怎么来就这么来吧。
解决方案四：
setLayout(null);add控件a后，a.setBounds(intx,inty,intwidth,intheight);其中x,y为位置坐标，可以利用dth,height来随意定义控件的大小
解决方案五：
setLayout(null);//布局为空的时候，小学习项目的话。根据自己的喜好，想怎么来就这么来吧。
解决方案六：
引用3楼zxqwxyql的回复:

精确，书上就是这么讲的
解决方案七：

如果要增加logo则要修改你目前的layout因此直接价格titleborder反而更直观，button可以修改setPreferredSize属性自己看红色代码
