compare two strings in java using command line arguments

Im a java noob. Basically I am trying to create a program that
compares two command line arguments while ignoring case and prints out the lesser of the
two strings. Here is what I have so
far:

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

            {
 String s1 = new String(args[0]);
 String s2 = new
            String(args[1]);

 if ( s1.compareToIgnoreCase(s2) > 0
            )
 System.out.println(s2);

 else if (
            s1.compareToIgnoreCase(s2) < 0 )
 System.out.println(s1);
 else
            
 System.out.println("Both strings are equal.");

            }
}

I keep
getting the error

Error: Could not find
            or load main class
            CompareString

when I
try to run it. What am I doing wrong?

"Error: Could
not find or load main class
CompareString"

Your
error message says you couldn't load class "CompareString", but your code says your
class name is
CompareStrings.
