Practice Program in java Day-10

Today I learned the new topic of String: find the length of last word in a string; program : class Solution { public int lengthOfLastWord(String s) { int last = s.length() - 1; while (last >= 0 && s.charAt(last) == ' ') {//to remove he spaces last--; } int start = last; while (start >= 0 && s.charAt(start) != ' ') { start--; } return last - start; } public static void main(String... args){ String a="fly of moon "; int S=lengthOfLastWlrd(a); System.out.println(S);} } }

Today I learned the new topic of String:
find the length of last word in a string;

program :
class Solution {
public int lengthOfLastWord(String s) {
int last = s.length() - 1;

    while (last >= 0 && s.charAt(last) == ' ') {//to remove he spaces
        last--;
    }

    int start = last;
    while (start >= 0 && s.charAt(start) != ' ') {
        start--;
    }

    return last - start;        
}
public static void main(String... args){
    String a="fly of moon ";
    int S=lengthOfLastWlrd(a);
    System.out.println(S);}

}
}
