Program to split string in n equal parts(using space as delimiter)

* @param args
*/
public static void main(String[] args)
{
int n = 3;
String s = "This is sample string which will be split in 3 parts";
int p = s.length() / n;
int w1 = 0;
int w2 = FindClosestWordIndex(s, p);
int w3 = FindClosestWordIndex(s, p * 2);
w2 = (w2==-1)?s.length():w2;
w3 = (w3==-1)?s.length():w3;
System.out.println("1."+s.substring(w1, w2).trim());
if(s.substring(w2, w3).trim().length()>0)
System.out.println("2."+s.substring(w2, w3).trim());
if(s.substring(w3).trim().length()>0)
System.out.println("3."+s.substring(w3).trim());
}
public static int FindClosestWordIndex(String s, int startIndex)
{
