    Default New to Java : Need help with my integers rules

    Hi everyone,

    I was unable to see the board last Java class so I have a quick/easy question. I was asked to write a basic program with mathematical expressions so I wrote the following:

    _____________________________________

    public class Assign01 {
    public static void main(String[] args) {

    // creating my int variables here
    int num1=0,num2=0,sumvalue=0,diffvalue=0,productvalue= 0,quotvalue=0,remaindervalue=0;


    Scanner sc = new Scanner(System.in);

    // straight forward
    System.out.println("Please choose your first number: ");
    num1 = sc.nextInt();
    System.out.println("Please choose your second number: ");
    num2 = sc.nextInt();

    // straight forward
    sumvalue = num1+num2;
    diffvalue = num1-num2;
    productvalue = num1*num2;
    quotvalue = num1/num2;
    remaindervalue = num1%num2

    _____________________________________


    Under this I wrote "System.out.println ..." to write the answers and explain tips about math.
    Can someone explain where can I add something like this?

    ______________________
    int subtract(){

    int result;
    if (num1 > num2)
    result = num1-num2;
    else
    result = num2-num1;

    return result;
    ______________________

    and something like this for division: "divide = if 15 divided by 0 = zero then return the value 0 as a result". Where would I add this in my program?

    Any help/guidance would be greatly appreciated.

    Regards,

    MartinRR
