Task: To save yourself the time it takes to solve basic math problems, you've decided to write a program to perform simple calculations. This class will need to utilize eleven methods to encapsulate all the required functionality. You are required to implement: Calculator.java Calculator Class Fields Name Type Access Modifier Description prevResult double private Stores the result of the most recent calculation count int private Stores the number of calculations Constructor Parameters Modifier(s) public None Methods Name Return Type Parameters Description add int int a, int b Return the result of adding a to b. subtract int int a, int b Return the result of subtracting b from a. multiply int int a, int b Return the result of multiplying a by b. divide double int a, int b Return the result of dividing a by b. Note: this method should do floating point division, not integer division. calculateCircleArea double intr Return the result of calculating the area of a circle with radius r. calculate Power int int a, int x Return the result of raising a to the power of x. getPrevResult double None Getter for prevResult. getPrevResult double None Getter for prevResult. getCount int None Getter for count. setPrevResult void double result Setter for prevResult. setCount void int count Setter for count. updateCount void None increments count by one. Hint: You may want to look into the Math class
