编写一个JFrame窗口

作业：编写一个JFrame窗口，要求如下：1. 在窗口的NORTH区放置一个JPanel面板。2. JPanel面板放置如下组件：(1) JLable标签，标签文本为“兴趣”，右边接着是三个JCheckBox多选按钮，选项分别是“羽毛球”、“乒乓球”、“唱歌”。可以多选。(2) JLabel标签，标签文本为“性别”，右边接着是两个JRadioButton按钮，选项分别是“男”、“女”。置成单选按钮，提示：使用ButtonGroup类 。(3) 兴趣标签及按钮放在第一行，性别标签及按钮放在第二行，分别借助两个行型Box容器安排这两行组件的位置，而两个行型Box容器放入JPanel面板中，要两行组件对齐的话，可以把JPanel面板设置两行一列的GridLayout布局。3. 窗口的CENTER区域放置一个JScrollPane容器，容器中放置一个JTextArea文本域。4. 当点击JCheckBox多选按钮和JRadioButton按钮时，如果是选中操作，则把选中项的文本显
