The problem is that, you're performing %, and / operations on a String.
try this...

import javax.swing.*;
class Demo
{
public static void main(String[] args)

{
int str;
String s;
int l,sum=0;

s=JOptionPane.s howInputDialog( " enter integer");
str=Integer.par seInt(s);


l=s.length();

for(int i=1;i<=l;i++)
{
sum=(str%10)+su m;
str=str/10;
}
System.out.prin tln("sum =" + sum);
System.out.prin tln("str =" + str);

}

}
