Program Plan Intro

Heap visualization

Program Plan:

• Import the required packages.
• Create a class “Myclass”:
  • New heap gets created.
  • New text field gets created.
  • New heap view gets created.
  • New button gets created.
  • Using start initialize the required.
    • New hbox gets created.
    • Set the count.
    • Add the label.
    • Set the style.
    • New border pane gets created.
    • Align and position the pane.
    • Create a scene based on the defined positions.
    • Set title for the preview.
    • Display the results based on the mouse action made.
    • The node gets add and removed based on the action defined.
  • Define the class “Heap”
    • New list gets defined.
    • New heap empty gets created.
    • Define the method “Heap()”
      • Loop that iterates to add the elements into the heap.
    • Define the method “add()”
      • Add the object.
      • Loop that iterates for the values present and add them after validation.
    • Define the method “remove()”
      • Condition to validate the elements of the list
      • Loop that iterates to remove the elements present in the list.
    • Define the method “getSize()”
      • Size of the list gets returned.
  • Define the class “HeapView()”
    • Declare and define the required varibles.
    • Call the method “repaint()”
      • Clear the pane.
      • Display the tree method is called.
    • Define the method “displayTree”
      • Condition to validate the value of the heap size.
      • New circle gets created.
      • Set the fill color and stroke color.
      • Add the elements at the required position based on the validation.
      • Display the heap.
    • Define the method “connectLeftchild”
      • Define the gap.
      • Set the x and y coordinates.
      • Add the elements.
    • Define the method “connectRightchild”
      • Define the gap.
      • Set the “x” and “y” coordinates.
      • Add the elements.
  • Define the main method.
    • Initialize the call.
