public class SampleB
{
public static void main(String args[])
{
String s1=args[0];
String s2=args[1];
System.out.println("s1=" + s1 + "s2=" + s2);
System.out.println("s1+s2=" + s1+s2);

int c1=Integer.parseInt(s1);
int c2=Integer.parseInt(s2);
System.out.println("c1=" + c1 + "c2=" +c2);
System.out.println("c1+c2=" + (c1+c2));
}
}

output:
