If you cannot find this window, go toWindow, then Show View, then Console.3. Next, you will add loops to validate all user input and handle exceptions so that code passes all test cases by completing the following:o Review the code, looking for the two code blocks where user input is required.o Implement a do-while loop in both blocks of code to ensure that input is valid and any exceptions are handled.o Use the two following sample sets of input to test your program. Since these inputs are invalid, your program should respond to each byprompting the user to enter valid input. This should continue to loop until valid input is received.Input 1: Input 2:thirty2530Think: Why is O invalid input for this problem? What is the user being asked to input?

Next, you will add loops to validate all user input and handle exceptions so that code passes all test cases by completing the following: o Review the code, looking for the two code blocks where user input is required. • Implement a do-while loop in both blocks of code to ensure that input is valid and any exceptions are handled. o Use the two following sample sets of input to test your program. Since these inputs are invalid, your program should respond to each by prompting the user to enter valid input. This should continue to loop until valid input is received.
