(In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…

(Recursive Greatest Common Divisor) The greatest common divisor of integers x and y isthe largest integer that evenly divides both x and y. Write a recursive function gcd that returns thegreatest common divisor of x and y. The gcd of x and y is defined recursively as follows: If y is equalto 0, then gcd(x, y) is x; otherwise gcd(x, y) is gcd(y, x % y), where % is the remainder operator.

(GREATEST COMMON DIVISOR) The greatest common divisor of integers x and y is the largest integer that evenly divides into both x and y. Write and test a recursive function gcd that returns the greatest common divisor of x and y. The gcd of x and y is defined recursively as follows: If y is equal to 0, then gcd (x, y) is x; otherwise, gcd (x, y) is gcd (y, x % y), where % is the remainder operator.
