    Look at the code that assigns a value to the variable: interest
    What happens to the value: (annualInterest/12) before it is assigned to interest?

    Doesn't it round down to 0? So it has to be double?

    0.004 is a double and doesn't need to be cast to double.

    I don't understand your last post. What does "suppose to see" mean?

    Do you know what is causing interest to be zero?
    Do you know how to change the code to keep interest from being zero?

    What did you mean in post#29? "round down to 0"

    Do some experimenting with casting double values to int to see what happens. Write a short test program with this statement. Compile and execute it:
    System.println((int)4.3); //  see what cast to int does
    Change the 4.3 to different double values to see what happens
