cant you just use substring?

Edit: new code

code:

import java.io.*;

public class substrings {

        public static void main(String[] args) {
                               
                InputStreamReader istream = new InputStreamReader(System.in);
                BufferedReader bufRead = new BufferedReader(istream);
               
                String text;
                String name1;
                String name2;
               
                System.out.println("enter your full name");
                try
                {
                text = bufRead.readLine();
                name1 = text.substring(0,text.indexOf(" "));
                name2 = text.substring(text.indexOf(" ")+1);
               
                System.out.println(name1);
                System.out.println(name2);
                }
                catch(Exception e)
                {
                        System.out.println("error occured");
                }
       
        }
}

here's an alternate way (lesser code) [wow you've got to love this language]:

code:

String input = "John Doe"; // lets suppose this is the input you get
String[] names = input.split(" ");

System.out.println(names[0]);  // First name
System.out.println(names[1]);  // Last name




works only with 1.4.x^ ( i haven't tested it )
