OVERVIEW This program focuses on heaps and using the GUI. INSTRUCTIONS Turn in Card.java, CardHeap.java and your main file. You are allowed to reuse your Card.java from a prior assignment with any necessary changes that you want to add. 3 Files should be submitted! IMPLEMENTATION DETAILS: You will reuse your Card.java file and you will write the GUI form and the CardHeap.java files to implement the necessary behavior. THE PROGRAM implement a simple GUI program that will randomly add/remove cards that are the same as the ones in prior assignments. (Note that we will be ignoring the premium cards, although they should still work.).
THE MAIN PROGRAM The GUI/main program should do the following: • The add button should create random card(default constructor) and then add it to the heap. • Pop should remove the smallest card from the heap. o It should then print the removed card in the label marked Last Removed • Clear should set the heap to empty. • Every time you press a button it should reset the top label to the toString() representation of the storage heap. In other words keep the labels updated. • When the program starts, the 2nd label can be blank if you want. CARD You should not need to make any significant change to the Card class, just make sure the compareTo method works correctly and the toString works correctly. Note you should be using compareTo in you heap, that is the cleanest solution. THE HEAP The heap should be a stored in an Array of Cards. I would not suggest trying to make a generic heap. You can use the PowerPoint/book as a guide on how to write it. The required methods you will need are: • public void add(Card x) • public Card remove() • public void clear() • private void expand() • public String toString() o Only print the used part of the array, do not print the entire storage array.
Card.java:
public class Card implements Comparable<Card> {
public int power;
public int toughness;
public Card() {
power = new Random().nextInt(100);
toughness = new Random().nextInt(100);
}
public Card (int x){
power = x;
toughness = x;
}
public Card(int Power, int Toughness) {
power = Power;
toughness = Toughness;
}
public int getPower() {
return power;
}
public int getToughness(){
return toughness;
}
public int getCost(){
return (int) Math.round(Math.sqrt(2 * power + toughness) * 10);
}
@Override
public String toString() {
return "[" + power + "/" + toughness+":" + getCost() + "]";
}
public void weaken() {
power -= 2;
toughness -= 2;
if (power < 1) power = 1;
if (toughness < 1) toughness = 1;
}
public void boost(){
power += 2;
toughness += 2;
if (power > 100) power = 100;
if (toughness > 100) toughness = 100;
}
@Override
public boolean equals(Object obj) {
if (!(obj instanceof Card)) return false;
Card other = (Card) obj;
if (other == null) return false;
return power == other.power && toughness == other.toughness;
}
public int compareTo(Card o) {
int val = Integer.compare(getCost(), o.getCost());
if (val != 0) return val;
val = Integer.compare(power, o.power);
if (val != 0) return val;
return Integer.compare(toughness, o.toughness);
}
}
