"Operator / is underfined" problem

Hi,

I'm working on an assignment question which is as follows:

One integer is a multiple of another integer if the remainder after dividing the first
integer by the second is zero. Write a program that tests whether one integer is a
multiple of a second integer. The program’s output could appear as follows:
Sample Output 1
A test of whether one integer is a multiple of a second integer.
Enter the first integer: 25
Enter the second integer: 5
25 is a multiple of 5 if the following value is zero: 0

I typed in the following code:

import java.util.Scanner;
public class Integer
{
public static void main (String [] args)
{
Scanner keyboard = new Scanner (System.in);
System.out.println ("A test of whether one integer is a multiple of a second integer");
System.out.println ("Enter the first integer ");
String integer1 = keyboard.nextLine ();
integer1 = integer1.trim ();
System.out.print ("Enter the second integer");
String integer2 = keyboard.nextLine ();
integer2 = integer2.trim ();
int remainder = integer1/integer2;

System.out.println (integer1 + "is a multiple of " + integer2 + "if the following value is zero: " + integer1/integer2);
}
}
I received the following:
1 error found:
File: E:\ICSAP\Integer.java [line: 14]
Error: The operator / is undefined for the argument type(s) java.lang.String, java.lang.String

Why can't I use the divide operator?

integer1 and integer2 are strings!
Read integers instead of strings, or parse the strings e.g. with Integer.parseInt(...) to an integer!

You cant perform integer operations on strings!!
