java - 如何在JTree java swing中显示BinaryTree

Question

我有二叉树类，当然还有节点类

public class Node {
     SomeClass somedata;
     Node leftChld;
     Node rightChld;
}

我需要在 JTree swing gui 组件中显示我的二进制文件。请给出执行此操作的示例。提前谢谢。

抱歉这个话题，我自己做的这是这里

 public void showInTree(DefaultMutableTreeNode rtCm,BNode rt){
  if (rt!=null) {
    StringBuilder str = new StringBuilder(String.valueOf(rt.numVal));
    if (rt.chVal!='\0'){
        str.append("--" + "(").append(String.valueOf(rt.chVal)).append(")");
    }
     DefaultMutableTreeNode newnode = new DefaultMutableTreeNode(str);
    rtCm.add(newnode);
    if (rt.leftBNode != null) {
        showInTree(newnode, rt.leftBNode);
}   
    if (rt.rightBNode!=null) {
        showInTree(newnode,rt.rightBNode);
    }
  }
}

这里是

 public void showInTree(DefaultMutableTreeNode rtCm,BNode rt){
  if (rt!=null) {
    StringBuilder str = new StringBuilder(String.valueOf(rt.numVal));
    if (rt.chVal!='\0'){
        str.append("--" + "(").append(String.valueOf(rt.chVal)).append(")");
    }
     DefaultMutableTreeNode newnode = new DefaultMutableTreeNode(str);
    rtCm.add(newnode);
    if (rt.leftBNode != null) {
        showInTree(newnode, rt.leftBNode);
}   
    if (rt.rightBNode!=null) {
        showInTree(newnode,rt.rightBNode);
    }
  }
}
