King Saud University College of Computer and Information Systems, Department of Computer Science CSC 113: Java Programming-II, Spring2011 Tutorial #5 : Inheritance MathOp represent a mathematical operation. We have only two operations: Add (+) and Subtract (-). Below is a description for all the attributes and methods: opSymbol The symbol of the operation. For example "+" for Add, and "-" for Subtract. op1, op2 The two operands of the operation (LHS and RHS operands). result(): double It should return the result of applying the operation on the two operands. toString(): String It should return the string representation of the operation with the two operands. i.e. op1 + opSymbol + op2 . MathOp + MathOp(opName: String) + result(): double + toString(): String # opSymbol: String Add + Add(op1: double, op2: double) + result(): double

Implement the above classes 2. Write a main class, in it: a. Define an array of MathOp with the size 3. b. Add these three operations to it : 5 + 3 , 2 – 1 , 10.5 + 5 using Add and Subtract . c. Loop through the 3 operaƟons in the array and print the string representaƟon of the operation and the result of each operation using the methods toString() and result() . You should get an output similar to this: 5 + 3 = 8 2 – 1 = 1 10.5 + 5 = 15.5...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
