You will create a Java class in BlueJ called Calculator.

The Calculator class will have the following:

An integer field called operand1. A second integer field called operand2. A constructor that takes no operands and initializes both fields to zero. A method setOperands that takes two integer parameters op1 and op2 and sets the values of operand1 to op1 and operand2 to op2. A method add that takes a single parameter called answer. The method then checks the answer provided against the sum of operand1 and operand2 and outputs a corresponding message. For example, if the current values of operand1 and operand2 are 3 and 6 respectively and the value of answer provided is 9 the message might look like this: 3 + 6 = 9 You are correct! If the answer provided does not match the actual sum the message might be: 3 + 6 = 9 You need more practice! A method subtract that is similar to add but for subtraction. A method multiply that is similar to add but for multiplication. A method divide that takes two parameters quotient and remainder. This method is similar to add but you must check both the quotient and remainder of the operation operand1 / operand2. In addition, you should check operand2 to prevent the possibility of division by zero.
