Please help me with this question. it drives me crazy!

Question about the task

Archived

Pls help me to find out why I can't pass the verification, it seems everything is correct. I checked when the string start with a space, or when there are multiple spaces between words. Everything looks exactly like the requirement. Btw, when I use Code Analysis, it shows unknown error, which is pretty strange. Please help me. Thank you.

Have you verified this. it should pass the test. it is working fine for me

I verified. The last condition keep failing with advise: Consider the fact that words might be separated by more than one space.

you are getting index out of bounds exception when the string is ended with space because of line 38. change the code to work for this case and you don't need to write separate for loop in else statement . this will do the work

if (string[0] != 32) {
            int b = string[0] - 32;
            string[0] = (char) b;
        }
        for (int i = 1; i < string.length; i++) {
            if (string[i - 1] == 32 && string[i] != 32) {

                int x = string[i] - 32;
                string[i] = (char) x;

            }
        }

Thanks for your help. But the last condition still failed. here is my revised code

package com.codegym.task.task08.task0823;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;

/*
Going national

*/

public class Solution {
    public static void main(String[] args) throws IOException {
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String s = reader.readLine();

        //write your code here
        char[] string = s.toLowerCase().toCharArray();


        if (string[0] != 32) {
            int b = string[0] - 32;
            string[0] = (char) b;
        }

        for (int i = 1; i < string.length; i++) {
            if (string[i - 1] == 32 && string[i] != 32) {

                int x = string[i] - 32;
                string[i] = (char) x;

            }
        }

        //System.out.print(string[0]);

        for (int i = 0; i < string.length; i++){
            System.out.print(string[i]);
        }

    }
}

solution

sorry i didn't saw this case previously. It may be due to the fact that if there is any other character (not alphabets) after the space it may change due to line 30 and 31. try using Character methods :

if (string[0] != 32) {
          string[0] = Character.toUpperCase(string[0]);
      }

      for (int i = 1; i < string.length; i++) {
          if (string[i - 1] == 32 && string[i] != 32) {
              string[i] = Character.toUpperCase(string[i]);
          }
      }
