Java TreeNode Interface

Today to write an Android program to see a Method Getchildat (); Do not understand its use of Baidu search for a bit, see its API, carefully look at the original interface inside now I put this API to share the assumption is that the operation of XML I think this is very convenient

TreeNode

Defines the requirements that can be used as objects for tree nodes in JTree.

Overridden equals TreeNode implementations often need to be rewritten as well hashCode . For a lot of other information, please refer to TreeModel . For a lot of other information and demonstration examples of using tree nodes, refer to the "How to" use Tree Nodes in the Java Tutorial .
