What about javax.swing.DefaultMutableTreeNode This is a purely data model class - ie it is not restricted nor linked to visual trees On Fri, Jan 08, 1999 at 05:07:08PM +0530, Karthik Vishwanath wrote: > HI all, > I need to generate a tree structure in my Java app. The size of > the tree cannot determined until runtime.

That solution would work fine, of course. The alternative is a `linked tree' structure. Binary trees are easy (just store each node's left and right children, and probably the parent). Trees with arbitrary numbers of branches are a little more complex. My preferred solution is for each node to store parent, first child, and `sibling', so to enumerate a node's children, you find the first child then follow it's sibling list. Unfortunately there isn't a standard tree class in the API, but you could implement a class for a tree of arbitrary objects and use that if you wanted.
