Help with this java program

[Daredevilpwn]

Hello guys. In my computer programming class I need to make a program that can compute the pocket change of any number specified by the user. So for example if I were to input 1.30 in the program it should output something like "You have 5 quarters" "You have one nickels" "You have 0 dimes" "You have 0 pennies" I understand this is most likely the most simplest question but I am stumped right now. What would be an appropriate algorithm for this task?
