Task: Loop, input, and variable review: objects not required. Write a Java program that can make change for a vending machine. Your program should take two numbers as input, one for the amount charged and one for the money given. You can assume both amounts are less than $10, and that the user will give more money than the amount due. Use the following U.S. coins: dollar, quarter, dime, nickel, penny. The program displays the number of each kind of coin to give back. Try to design your program so that it returns the fewest number of coins possible. Output of a sample program run: You bought something worth $1.25. You paid $2.10. Your change is: 0 dollar coins 3 quarters 1 dimes 0 nickels 0 pennies
