I'm trying to implement a Breadth-first traversal in the application class use a queue and a binarysearchtree..I'm getting an error

public void breadthFirst( TreeNode tNode)
Queue q = new Queue( );
if( q.isEmpty() )
q.enqueue( this );

while( !q.isEmpty() )



E:\ICS\ICS 211 Projects (Fall 04)\Final Exam\211final_src\ cannot resolve symbol
symbol : class TreeNode
location: class FinalDataTypesTest
public void breadthFirst( TreeNode tNode)
1 error

Its because your method cannot find the class TreeNode.
If you are using the TreeNode from the swing library you need to import javax.swing.tree.TreeNode to make it work
