Complete the code for this PiggyBank class. I have also included a main program (TestPiggy) for you to use to test your class. When I grade your PiggyBank class, I will use this exact same main program so be sure your class compiles and runs with it. I have also attached a screenshot of what your output should look like. Note the way the numeric values are formatted; yours should be the same.

public class PiggyBank implements Measurable, Comparable {

private int numNickels, numPennies, numDimes, numQuarters;

// to do; complete the constructor

public PiggyBank() {

}

// to do; complete the constructor

public PiggyBank(int quarters, int dimes, int nickels, int pennies){

}

// to do; it just returns 0; code it so that it returns the monetary

// amount of the piggy bank

public double getMeasure(){

return 0.0;

}

// to do; it just returns 0; code it so that it correctly compares

public int compareTo(Object other){

return 0;

}

// to do; it just returns a blank string right now

public String toString(){

return "";

}

}

public class Data{ public static double average(Measurable[] objects){ double sum = 0; for (Measurable obj : objects){ sum = sum + obj.getMeasure(); } if (objects.length > 0){return sum / objects.length;} else {return 0;} } }
