Java Eclipse

The below code prints out each letter on a different line.

I need it to print out each WORD on a different line.

for instance, if the input is bob the builder i need it to print out

bob

the

builder

import java.util.*;

public class CommandLine {

public static void main(String[] args) {

String words2 ;

Scanner input = new Scanner(System.in);

words2= input.nextLine();

int i,j;

for (i=0; i <= words2.length() -1; i++) {

if (words2.substring(i).startsWith("") || i ==0){

for (j = i + 0; j <= words2.length(); j++){

if(words2.substring(j).startsWith("") || j == words2.length())

{ System.out.println(words2.substring(i,j));

i = j;

input.close();

}

}

}

}

}

}
