Question

用java怎么编出下面的窗口界面?急啊，谢谢了

可以只说明这个窗口界面是怎么做的，里面的各个下拉选项栏，按钮怎么安排上去的，还有那个excel怎么添加进去的，其他的我自己可以实现，谢谢了

首先注意到没有最大化和最小化，那么是个JDialog.
左上角图标换了，用JDialog的setIconImage方法来设置。
内部上面定高，下面填满高。用BorderLayout,上JPanel,下JPanel
上JPanel竖排，用BoxLayout，里面两个JPanel
两个JPanel设置边框，用TitledBorder.然后显然是GridLayout.每个里面JPanel
每个JPanel输入部分定宽，左边拉伸，用BorderLayout,右为JTextField或者JComboBox，左JLabel
下JPanel设置边框，用TitledBorder.内部是JScrollPane套一个JTable，不是什么Excel，另外JTable是极度复杂极度强大的，多花点时间学它的源代码比较好
