Question

This is Java Programming! We are working with MaxHeap

 

Instructions: Don't modify the two codes below. You need to make a MaxHeapInterface.java that implements the bstMaxHeap in the Driver.java code. If you haven't look at the code, look at them now.

 

Driver.java code:

/**
  A driver that demonstrates the class BstMaxHeap.
  
  @author Frank M. Carrano
  @author Timothy M. Henry
  @version 5.0
*/
public class Driver 
{
public static void main(String[] args) 
{
 String jared    = "Jared";
 String brittany = "Brittany";
 String brett    = "Brett";
 String doug     = "Doug";
 String megan    = "Megan";
 String jim      = "Jim";
 String whitney  = "Whitney";
 String matt     = "Matt";
 String regis    = "Regis";
 
 MaxHeapInterface<String> aHeap = new BstMaxHeap<>();
 aHeap.add(jared);  
 aHeap.add(brittany);
 aHeap.add(brett);
 aHeap.add(doug);  
 aHeap.add(megan);
 aHeap.add(jim);
 aHeap.add(whitney);  
 aHeap.add(matt);
 aHeap.add(regis);
 
 if (aHeap.isEmpty())
  System.out.println("The heap is empty - INCORRECT");
 else
  System.out.println("The heap is not empty; it contains " +
                     aHeap.getSize() + " entries.");
 
 System.out.println("The largest entry is " + aHeap.getMax());
 
 System.out.println("\n\nRemoving entries in descending order:");
 while (!aHeap.isEmpty())
  System.out.println("Removing " + aHeap.removeMax());

  
 System.out.println("\n\nTesting constructor with array parameter:\n");
 String[] nameArray = {jared, brittany, brett, doug, megan, 
                       jim, whitney, matt, regis};
 MaxHeapInterface<String> anotherHeap = new BstMaxHeap<>(nameArray);
 
 if (anotherHeap.isEmpty())
  System.out.println("The heap is empty - INCORRECT");
 else
  System.out.println("The heap is not empty; it contains " +
                     anotherHeap.getSize() + " entries.");
 
 System.out.println("The largest entry is " + anotherHeap.getMax());
 
 System.out.println("\n\nRemoving entries in descending order:");
 while (!anotherHeap.isEmpty())
  System.out.println("Removing " + anotherHeap.removeMax());
}  // end main
}  // end Driver

 

HERE IS THE OUTPUT WE'RE SUPPOSED TO GET AFTER WE MAKE THE MAXHEAPINTERFACE CODE:

/*
The heap is not empty; it contains 9 entries.
The largest entry is Whitney


Removing entries in descending order:
Removing Whitney
Removing Regis
Removing Megan
Removing Matt
Removing Jim
Removing Jared
Removing Doug
Removing Brittany
Removing Brett


Testing constructor with array parameter:

The heap is not empty; it contains 9 entries.
The largest entry is Whitney


Removing entries in descending order:
Removing Whitney
Removing Regis
Removing Megan
Removing Matt
Removing Jim
Removing Jared
Removing Doug
Removing Brittany
