Process Heap Solution

Create a couple of classes that will simulate a process heap.  Download the driver and follow the following instructions!

 

 

Create a class called Process

Instance variables:
Priority: which is an integer value that corresponds to where it will be in the heap. Needs to be greater than 0.
Time: A double value that corresponds to how long the process will take to run.  Needs to be greater than 0.
Name: A string value that is the name of the process
Constructors: Default and Parameterized
Accessors and mutators for each instance variable
Make sure to check for valid values.
Other methods:
toString: a method that prints out the name, priority, and time
Create another class called ProcessHeap

Instance variables:
Heap: an array of type Process which represents the heap
Size: the number of elements in the heap
Constructors: Default and parameterized
Other methods:
insert: this method which returns nothing adds a new element to the heap. It always adds the next element as the next element in breadth order and then bubbles it up based on the priority of the Process.
peek: this returns the head of the heap
remove: This returns the root of the heap and then removes it from the heap.  It must then move the last element in the heap (via breadth order) to the root and bubble that value down until it’s in the correct location.
printHeap: Prints the heap out in breadth order
isEmpty: returns a true or false value for whether or not the queue is empty
heapSort: Prints out the heap in sorted order.  The idea is to remove an element print that element and then repeat that until there are no more elements.
 

 

Example Print Out:

The current heap is:

e 33 23.0

c 20 18.0

d 18 29.0

g 16 5.0

b 5 20.0

f 1 15.0

a 10 50.0

Starting simulation

Process: e 33 23.0 is starting

Process: e 33 23.0 has ended

Process: c 20 18.0 is starting

Process: c 20 18.0 has ended

Process: d 18 29.0 is starting

Random process added! Random Process 50 10 10.0

Process: d 18 29.0 has ended

Process: g 16 5.0 is starting

Process: g 16 5.0 has ended

Process: a 10 50.0 is starting

Random process added! Random Process 100 20 20.0

Process: a 10 50.0 has ended

Process: Random Process 100 20 20.0 is starting

Random process added! Random Process 150 30 30.0

Process: Random Process 100 20 20.0 has ended

Process: Random Process 150 30 30.0 is starting

Process: Random Process 150 30 30.0 has ended

Process: Random Process 50 10 10.0 is starting

Process: Random Process 50 10 10.0 has ended

Random process added! Random Process 200 40 40.0

Process: Random Process 200 40 40.0 is starting

Process: Random Process 200 40 40.0 has ended

Process: b 5 20.0 is starting
