Question 6. [45 points] The next 9 questions deal with a class named Calculator. Class Calculator is to have the following private double - valued attribute. - runningTotal - represents the value (running total) of the current calculation. Class Calculator is also to have the following public methods. - Calculator () - default constructor that configures the calculator to have a running total of 0. - Calculator (double v) - specific constructor that configures the calculator to have a running total of v. - void clear () - scts the running total of the calculator to 0. - double getTotal( ) - returns the running total of the calculator. - void add(double v) - increments the running total by amount v. - void divide (double v ) - if v is non-zero, then its sets the running total of the calculator to the value of the current running total divided by v. Otherwise, it sets the running total of the calculator to the double value Double. NaN. - Object clone() - returns a new Calculator with the same running total as this calculator. - boolean equals (Object v ) - returns whether its parameter is a Calculator with the same rumning total as this calculator. - String toString() - returns a String representation of the running total. One of the String class value0f () methods may prove helpful here
