Write complete Java programs for all the problems and compile and run and make sure that the program works correctly. 1. Write a program that reads in a code (C for circumference and A for area) and the radius ofa circular pool, computes and displays the circumference or the area depending on the code entered. Use a switch statement for the selection. If the user enters any other character (other than C or A), the program should display that it is an invalid choice. (Formulas: Area IIr2, Circumference 2Tr, where -3.14159, and r is the radius). 2. A bank charges a base fee of $10 per month, plus the following check fees for a commercial checking account: $0.10 each for less than 20 checks $0.08 each for 20-39 checks $0.05 each for 40-59 checks $0.04 each for 60 or more checks Write a program that requests the number of checks the bank's service charges for the month
