java如何实现自定义窗口

用jframe试试，可以自定义窗口，并设置布局类型，然后用图片控件设置背景图或在界面放置图片，有自适应界面的方法

用java怎么编出下面的窗口界面?急啊，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

-----------------觉得有点复杂，你初学的话可能搞不定，试着帮你写了一个，尽量看懂吧--------

用Java语言设计一个界面，

首先：采用什么技术实现

java语言可以使用awt 和swing等技术实现图形界面

推荐使用Swing，因为Swing比AWT更专业，更漂亮，组件更丰富，功能更强大。

2. 其次：分析采用什么布局

边界布局BorderLayout，配合表格布局GridLayout，既简单又美观

3. 最后：分析需求中需要用的组件

学生姓名学号显示信息需要用到文本框JTextField

单选按钮需要用到组件 JRadioButton

复选框需要用到组件 JCheckBox

组合框需要用到组件 JComboBox

图片效果

参考代码如下

//导入所需要的包
