求学生用JAVA创建窗口
求一个用JAVA的swing创建窗口，第一个要求有两个列表（两个列表都是两条内容），选中列表中的内容点击确定后可以显示不同的窗口（共有四种不同窗口），显示的窗口有三个不同名称的按钮（其中一个可以点击就行），点击后显示一个文本窗口（文本内容：结束）
完整代码如下：
public static void main(String[] args) {
JFrame jFrame = new JFrame();
jFrame.setLocationRelativeTo(null);
jFrame.setSize(600, 400);
jFrame.setLayout(new GridLayout(2, 1));
String[] contents = {"标题1", "标题2"};
JList<String> listBox = new JList<>(contents);
listBox.setSize(100, 100);
listBox.setBorder(BorderFactory.createTitledBorder("列表1"));
listBox.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
listBox.setVisibleRowCount(-1); // to keep all values visible
listBox.setSelectedIndex(3);
listBox.addListSelectionListener(e -> {
JList list = (JList) e.getSource();
Object value = list.getSelectedValue();
if("标题1".equals(value)) {
JOptionPane.showMessageDialog(jFrame, value);
} else {
JOptionPane.showConfirmDialog(jFrame, value);
}
});
String[] contents2 = {"标题1", "标题2"};
JList<String> listBox2 = new JList<>(contents);
listBox2.setSize(100, 100);
listBox2.setBorder(BorderFactory.createTitledBorder("列表2"));
listBox2.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
listBox2.setVisibleRowCount(-1); // to keep all values visible
listBox2.setSelectedIndex(3);
listBox2.addListSelectionListener(e -> {
JList list = (JList) e.getSource();
Object value = list.getSelectedValue();
if("标题1".equals(value)) {
JOptionPane.showInputDialog(jFrame, "请随便输入点啥");
} else {
JOptionPane.showConfirmDialog(jFrame, value, "title", YES_NO_OPTION, INFORMATION_MESSAGE);
}
});
jFrame.add(listBox);
jFrame.add(listBox2);
jFrame.setVisible(true);
}
运行结果如下
如有帮助，请采纳，十分感谢！
swing现在很少用了
swing 到盲区了
