I got a problem where NULL values should also act a role in my program. But when I use StringTokenizer class to split, it eliminates null values, so I have written my own program that will help me to give null values.

import java.util.*;

public class Split

{

        public String[] split(String str,char x)

        {

                Vector v=new Vector();

                String str1=new String();

                for(int i=0;i<str.length();i++)

                {

                        if(str.charAt(i)==x)

                        {

                                v.add(str1);

                                str1=new String();

                        }

                        else

                        {

                                str1+=str.charAt(i);

                        }

                }

                v.add(str1);

                String array[];

                array=new String[v.size()];

                for(int i=0;i<array.length;i++)

                {

                        array[i]=new String((String)v.elementAt(i));

                }

                return array;

        }

        public static void main(String s[])

        {

                Split ss=new Split();

                String array[];

                array=ss.split(s[0],s[1].charAt(0));

                for(int i=0;i<array.length;i++)

                System.out.println(array[i]);

        }

}

Example: String str=”Koundinya,,”progarmer”;

StringTokeizer st=new StringTokenizer(str);

Split ss=new Split();

String array[];

array=ss.split(str,’,’);

StringTokenizer will split this into Koundinya and programmer

But  Split.class gives result as Koundinya null and programmer

I hope this program will help the beginners
