Write a class called Calculator that performs simple integer arithmetic on the command line arguments. Your application will take a single integer followed by an operator (see below), followed by another integer. Your Calculator class must support the following operators: additions (+), subtraction (-), multiplication (x), and division (), exponentiation (^). You may write the logic in the main function. You need not instantiate an instace of the Calculator class to make it run. The invocation and output should be as follows: C:\IS147\test> java -cp . Calculator 6 / 3 Calculator: 6 / 3 = = 2 C:\IS147\test> java -cp. Calculator 6 x 2 Calculator: 6 x 2 = 12 C:\IS147\test> java -cp. Calculator 6 + 4 Calculator: 6 + 4 10 3 C:\IS147\test> java -cp. Calculator 6 Calculator: 6 - 3 = 3 C:\IS147\test> java -cp. Calculator 6 ^ 3 Calculator: 6 ^ 3 = 216
