The results is correct but there is even the same error with or without external method

package com.codegym.task.task08.task0823; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; /* 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(); String res = ""; String[] block = s.split(" "); for (int i = 0; i <block.length ; i++) { int blockLenght = block[i].length(); String firstUpper = block[i].substring(0,1).toUpperCase(); String lestUpper = block[i].substring(1,blockLenght); res+=(firstUpper + lestUpper + " "); } System.out.println(res); // firstUpperCase(s); } // public static void firstUpperCase(String data){ // String res = ""; // // String[] block = data.split(" "); // // for (int i = 0; i <block.length ; i++) { // int blockLenght = block[i].length(); // String firstUpper = block[i].substring(0,1).toUpperCase(); // String lestUpper = block[i].substring(1,blockLenght); // res+=(firstUpper + lestUpper + " "); // } // System.out.println(res); // } }

Try:

System.out.println(res.trim());

Thanks but, i try with both kind of request( in line and external method.) Even the same problem.

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

//        for (int i = 0; i <block.length ; i++) {
//            int blockLenght = block[i].length();
//            String firstUpper = block[i].substring(0,1).toUpperCase();
//            String lestUpper = block[i].substring(1,blockLenght);
//            res+=(firstUpper + lestUpper + " ");
//        }
//        System.out.println(res.trim());
        firstUpperCase(s);

    }
    public static void firstUpperCase(String data){
        String res = "";

        String[] block = data.split(" ");

        for (int i = 0; i <block.length ; i++) {
            int blockLenght = block[i].length();
            String firstUpper = block[i].substring(0,1).toUpperCase();
            String lestUpper = block[i].substring(1,blockLenght);
            res+=(firstUpper + lestUpper + " ");
        }
        System.out.println(res.trim());
    }
