public class eventFrame extends JFrame {
  JSplitPane jSplitPane1 = new JSplitPane();
  JTree jTree1 = new JTree();
  public eventFrame() {
    try {
      jbInit();
    }
    catch(Exception e) {
      e.printStackTrace();
    }
  }
  private void jbInit() throws Exception {
    DefaultMutableTreeNode root=new DefaultMutableTreeNode("信用卡系统");
     DefaultMutableTreeNode bitchThing=new DefaultMutableTreeNode("查询");
        root.add(bitchThing);
        bitchThing=new DefaultMutableTreeNode("存款");
        root.add(bitchThing);
        bitchThing=new DefaultMutableTreeNode("取款");
        root.add(bitchThing);
        jTree1=new JTree(root);
    jTree1.addTreeSelectionListener(this);
        int mode  =TreeSelectionMode1.SINGLE_TREE_SELECTION;
        jTree1.getSelectionModel().setSelectionMode(mode);

    this.setState(Frame.NORMAL);
    this.getContentPane().setLayout(null);
    jSplitPane1.setBounds(new Rectangle(200, 164, 164, 27));
    jTree1.setBounds(new Rectangle(10, 10, 72, 299));
    this.getContentPane().add(jTree1, null);
    this.getContentPane().add(jSplitPane1, null);
    jSplitPane1.setDividerLocation(100);


 }
}

错误的地方：
DefaultMutableTreeNode root=new DefaultMutableTreeNode("信用卡系统"); //第一个错误
DefaultMutableTreeNode bitchThing=new DefaultMutableTreeNode("查询");//第二个错误
root.add(bitchThing);
bitchThing=new DefaultMutableTreeNode("存款");//第三个错误
root.add(bitchThing);
bitchThing=new DefaultMutableTreeNode("取款");//第四个错误
root.add(bitchThing);
jTree1=new JTree(root);
jTree1.addTreeSelectionListener(this);//第五个错误
int mode =TreeSelectionMode1.SINGLE_TREE_SELECTION;//第六个错误
jTree1.getSelectionModel().setSelectionMode(mode);

第一个到第四个问题: 需要javax.swing.tree.DefaultMutableTreeNode类,引入类或者包..
第五六个问题: 构造方法之外不能直接使用this.

以上喵~``

[cangyue87]

更正第五个问题: 是TreeSelectionModel而不是TreeSelectionMode1,1和l要分清啊喵~``

[cangyue87]

改了改lz的代码,这是一个可以编译的版本喵~``...
