SIMPLE CALCULATOR The SimpleCalculator class as its name implies, implements the functionality of a simple calculator (one that can add, subtract, and multiply istegens). ASiapleCalcater has to keep track of an "accumulator an integer variable that holds the value currently stored in the calculator. The initial value of the accumulator is 0. Here is a summary of the methods of SimpleCalculator add: This method takes an integer nount and increments the accumulate by getal: t takes a parameters and returns an integer which is the currently stored in the accumulator serval: It takes an integer valur , and sets the value of the accur subtract: This method takes on integer amount and decreets t accumulator by multiply: This method takes an integer amounts and multiples th accumulator byx 5G OCS510 AUK AMERICAN ESIVERITY KUWAIT 43593751 BROUND of the e of the 2.

Its name is testsomethod and all it does is fall. If you g the "RunTest Project mens, Netbeans will run your tests and give you are case, it will say that "1 test failed" which is what we expect So, let's start coding and eng Let's add the method getale to our code.

If you go to the "RunTest Project" wm, Netbeanwill your and give you a reprt is this case it will say that "The test passa which is what we Now add the following test case Your code, of course, won't comple now because you have met defound the setvalue method yet. So let's do that. Add the code for setvalue (lited below and run your s Make sure everything works moothly. Now it's your turn. Implement the remaining methods and add tests for each it is recommended that you follow a Test a little. Code a little development style instead of writing all of your code and testing all C130 WI Done Your final code should contain all five methods for simplecalculator as well at least live test cases that cover these methods.
