Thanks for any help, whl > having some trouble writing this program and having to use > Interger.parseInt, and the JOptionPane options also. > > Thanks for any help, > whl The Calender class http://java.sun.com/j2se/1.4.2/docs/api/java/util/Calendar.html should help you deal with the time formatting issues. ok so as of now i have and input box that opens stating to enter number of minuets to be converted. That part is fine so now i am having to to stat what is entered to be taken and done out to find nuber of days,hrs,mins. and using the % operator and the /60 and then i am getting lost and not sure how to go about this thanks, whl >ok so as of now i have and input box that opens stating to enter number >of minuets to be converted.

You must use integer division and remainder (modulus, %) even if you can think of a way to do this without them. If the original number of minutes is stored in an int variable named minutes, then the number of hours is minutes / 60. See page 78 of the text for a little more about integer division. The number of minutes remaining after that number of hours has been accounted for is minutes % 60. See page 78 of the text for more on remainder. See also below. Note on integer division and remainder: If the values on both sides of a / (division) operator are integers, the result will also be an integer. Integers cannot represent a fractional value. That means that 5/2 cannot be what we might expect (2.5), but is, in fact, the whole part of the resulting value (2). The remainder is what remains after integer division. In grade school you learned that 16/3 is 5 with aremainder of 1. The remainder operator, %, evaluates 16 % 3 as 1.Both division and remainder work the same if either or both of the operands is an integer variable instead of an integer constant. Thus if we had a Java program with the following statements in it: int a = 16, b = 5, c, d; c = a / b; d = a % b; // c would now have the value 3 and d would have the value 1 </quote> - Oliver Free MagazinesGet these publications absolutely FREE for up to 12 months.
