Thread: how do i split a string into two parts and test if the second part of string is empty

Hi guys i am trying to divide a single string into two parts but am having abit of a problem here. i am getting a wrong error message. i wanted to get the invalidnameexception error but instead i am getting a arrayindexoutofbound error.

Is there other way that i can split the string and test if the second string is empty would like to print out the invalidnameexception. i have done alot of research but i just cant seem to find the problem.

import java.util.Scanner;
import javax.naming.InvalidNameException;
public class Name{
 
	public static void printName(String name) throws InvalidNameException{
 
		String[] seperator = name.split(" ");
		String firstName = seperator[0];
		String lastName = seperator[1];
 
 
		for (int i=0; i<seperator.length; i++) {
        if (seperator[i] == null) 
           throw new InvalidNameException("invalid name!");
 
 
 
 
        }
 
		System.out.println(firstName);
		System.out.println(lastName);
 
 
 
 
 
 
		}
 
 
	public static void main(String[] args){
		    	Scanner kb = new Scanner(System.in);
		    	System.out.println("please enter name:");
		    	String fullname = kb.nextLine();
 
 
		try{
			Name.printName(fullname);
 
			}catch (InvalidNameException e1){
				System.out.println(e1);
				}
 
		}
 
 
 
 
 
 
	}

You should use something like this
