You are required to build a class ArithematicProblem that represent a binary arithematic problem such as addition, subtraction, multiplication and division. The ArithematicProblem class is a super class which is there to provide the most generic version of the ArithematicProblem concept. This class has following instance variables 1. Operator1 (double) 2. Operator2 (double) 3. Answer(double) 4. Error(boolean) The value of Operator1 and Operator2 will be initialized through parameters in the constructor while the value of answer is Double.POSITIVE_INFINITY and error is false by default. Provide getters for all but setters for only operand1 and operand2 Provide the toString method so that the string representation of each operation the standard representation in mathematics i.e. if its an addition problem then it should be printed as 2 + 3 = 5 and so on. Provide a method double solve() in this class. This method performs the arithematic operation on the operands, calculates answer, sets the value of answer and returns it. If an error occurs in the calculation then the error is set to true and answer remains Double.POSITIVE_INFINITY. Since in the super class ArithematicProblem, we do not know what to do (beccause it is not one of the standard 4 operations), you will simply return the answer (Double.POSITIVE_INFINITY) Now provide the subclasses AdditionProblem, SubtractionProblem, MultiplicationProblem and DivisionProblem. All of these class inherit from ArithematicProblem. Provide appropriate constructors and the toString method. Now override the solve method in each of these class to do the appropriate operation. i.e. If it is AdditionProblem then you will add the operands in the solve method, set the answer to the sum obtained and return this value. In subtraction you will do subtration and multiplication the product. However, in division, you will perform the division but if the divisor i.e. the second operand is 0 then the division goes into error. So you will check for this situation and if the divisor is O then you will not solve, rather set the error to true and return the answer unchanged. (L.e. POSITIVE_INFINITY, the default value). Other instructors will be given in the class -I-X + 1
