I want to create a tree data structure [not binary tree nor JTree] with unlimited branch and I can go in each branch in that tree. Anyone can give me an example? or URL link..

Thanks

Maybe something like this?

import java.util.*;

public class NaryTree
{
  private ArrayList children = new ArrayList();
  private Object value;

  public NaryTree(Object value)
  {
    this.value = value;
  }

  public NaryTree getChild(int n)
  {
    return (NaryTree)children.get(n);
  }

  public void putChild(int n, NaryTree child)
  {
    children.add(n, child);
  }

  public Object getValue()
  {
    return value;
  }

  public void setValue(Object value)
  {
    this.value = value;
  }
}

Of course, this is basically just an ArrayList with a value associated with it.  So you could just extend ArrayList, add the value getter and setter, and have your N-ary tree.  But the code might be a little harder to understand without some good Javadocs.
