Add a static variable named totalInstances. Each time you construct a class, this variable should be incremented by 1. Adjust your toString method to also print the total number of times the class has been created on a different line than the Month name.

Then Create a test class to test the code

public class Month {

private int monthNumber;

private String monthName;

private static String[] names = {"Undecided", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};

public Month() {

setMonthNumber(1); }

public Month(int month) { setMonthNumber(month); }

public Month(String stringIn) { Boolean isSet = false; for(int i = 0; i < names.length; i++) { if(stringIn.equalsIgnoreCase(names[i])) { setMonthNumber(i); isSet = true; break; } }

if(!isSet) { setMonthNumber(1); } }

public void setMonthNumber(int intIn) { if(intIn < 1 || intIn > 12) { monthNumber = 1; setMonthName(1); }

else

{ monthNumber = intIn; setMonthName(intIn); } }

private void setMonthName(int intIn) { monthName = names[intIn]; }

public int getMonthNumber() { return monthNumber; }

public String getMonthName() { return monthName; }

public String toString() { String monthOut = "The month is " + getMonthName(); return monthOut; } public Boolean equals(Month objIn) { Boolean isEqual; if(this.getMonthNumber() == objIn.getMonthNumber())

{ isEqual = true; }

else

{ isEqual = false; }

return isEqual;

}

public Boolean greaterThan(Month objIn)

{ Boolean isGreater;

if(this.getMonthNumber() > objIn.getMonthNumber())

{ isGreater = true; }

else

{ isGreater = false; }

return isGreater; }

public Boolean lessThan(Month objIn) { Boolean isLess; if(this.getMonthNumber() < objIn.getMonthNumber()) { isLess = true; }

else

{ isLess = false; } return isLess; } }

Create a Test class that tests everything in the code
