Question about the task

String array in reverse order

Java Syntax, Level 7, Lesson 4

Under discussion

pls tell me

package com.codegym.task.task07.task0702; import java.io.BufferedReader; import java.io.InputStreamReader; /* String array in reverse order */ public class Solution { public static void main(String[] args) throws Exception { //write your code here BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String[] str = new String[10]; for(int i=0;i<8;i++){ str[i] = reader.readLine(); } str[8] = "hello"; str[9] = "hi"; /*for(int i=0;i<10;i++){ System.out.println(str[i]); }*/ //System.out.println(); String[] t = new String[str.length]; for (int i = 0; i < str.length; i++) { t[i]= new StringBuilder(str[i]).reverse().toString(); } for(int i=0;i<t.length;i++){ System.out.println(t[i]); } } }

until line 26 looks good and simple, from 26 you gone into a complicated way.. try it simple: go with one reverse for loop on hole array and print the index in the loop block code, (int i = str.length - 1; i >= 0; i--)

just add the strings in a for loop with reader.readLine() like you have and then use a for loop to iterate through backwards while printing. you over complicated it a bit. also dont try to set strings to a value yourself since it doesnt say to

My solution

public class Solution {
    public static void main(String[] args) throws Exception {
        String[] list = populateArray();
        reverse(list);
    }

    public static String[] populateArray() throws IOException {
        // Create and populate the array
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String[] list = new String[10];

        for (int i = 0; i < 8; i++) {
            String s = reader.readLine();
            list[i] = s;
        }
        return list;


    }

    public static void reverse(String[] array) {
        for (int i = 9; i > -1; i--)
            System.out.println(array[i]);

    }
}

//bro use this
package com.codegym.task.task07.task0702;

import java.io.BufferedReader;
import java.io.InputStreamReader;

/*
String array in reverse order

*/

public class Solution {
    public static void main(String[] args) throws Exception {
        //write your code here
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String[] satya = new String[10];
        int i = 0;
        while (i < 8){
            satya[i] = reader.readLine();
            i++;
        }
        satya[8] = "You are a hero";
        satya[9] = "You are the greatest person in the world";
         System.out.println(satya[9]);
        System.out.println(satya[8]);
        System.out.println(satya[7]);
        System.out.println(satya[6]);
        System.out.println(satya[5]);
        System.out.println(satya[4]);
        System.out.println(satya[3]);
        System.out.println(satya[2]);
        System.out.println(satya[1]);
        System.out.println(satya[0]);
    }
}

instead of creating a new string array, you could display the array str, by initializing i to 9 and then decrement the value of i in each loop
