    Default Print out object that is in a tree

    I am trying to print out the object in a tree. I have a toString method defined for the object. However, I get this error:

    I get a classCastException

    Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [LPriorityQueueNode;
    at PriorityQueue.printPriorityQueue(PriorityQueue.jav a:49)
    at driver.main(driver.java:63)


    System.out.println( tree[0].getElement());

    Default Re: Print out object that is in a tree

    I think it returns a Node object
    try

    getElementName() or getElementValue()

    to get the name n value of node,I m not sure weather it works or not
