help!simple coding problem..

[nicky_85]

im doing a practical, which asks the user to enter two numbers and print the sum, product, difference and division of the numbers.following is my code:

import java.util.*;
class Testing{
public static void main (String [] args){
Scanner s=new Scanner(System.in);
System.out.println("Pls enter the 1st num");
int a =s.nextInt();
System.out.println("Pls enter the 2nd num");
double b=s.nextDouble();

System.out.println("The sum is :" + (a+b));
System.out.println("The division is :" + (a/b));
System.out.println("The different is :" + (a-b));
System.out.println("The product is :" + (a*b));
}
}

this program can run, but my question is:
1) for different, if num a < num b, negative will appear, how if i dunwan the negative appear?
2) i wan to make the answer for division become 2 decimal, how to solve it?

hope somebody can guide me.thx!

For the difference, you could get the absolute value using the java.lang.Math class.

To get decimal results, you will need to use a different type of number. Use a double or float for both numbers, or type cast the int variable to a double or float.
