Savings account balance comparison code.

I have a savings account assignment which includes the following step:
a public method of the appropriate type called equals which will compare two accounts and return true if both savingsBalance values are the same - accurate to 4 digits after the decimal point.

I have it working with a boolean method in the main file, but was wondering if there is a way for a method in the program file to get the values from the main file so that the boolean method can be in the program file with the rest of my methods.
