Length of Last Word Interviewbit solution

Idea is to get last index of a whitespace and return length-lastindex-1

-1 is deducted because access starts from 0 index.

Code:

public class Solution {
public int lengthOfLastWord(final String a) {
   String temp=new String(a.trim());
   int len=temp.length();
   return(len-temp.lastIndexOf(" ")-1);
}
}
