I am not able to understand 3 and 4th requirements Pls explain with required input and output Reply asap

package com.codegym.task.task07.task0702; import java.io.BufferedReader; import java.io.InputStreamReader; /* String array in reverse order 1. Create an array of 10 strings. 2.

The program must create an array of 10 strings. 2. The program should read 8 strings for the array from the keyboard. 3. The program should display 10 strings, each on a new line. 4.

BufferedReader r= new BufferedReader(new InputStreamReader(System.in)); String[] a=new String[10]; a[8]="9"; a[9]="10"; for(int i=0; i<8; i++){ a[i]=r.readLine(); } for(int i=0; i<10; i++) { int j=a.length-i-1; System.out.println(a[j]); }

Thanks Serg --- * zero based index from 9 to get 10 output & i -- (vs ++) to count down in descending order ... cool

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

import java.io.BufferedReader;

/*

*/

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++;

I never thought that we need to manually print the line in reverse order without using loop, strange but worked,,, String[] arr = new String[10]; BufferedReader read = new BufferedReader(new InputStreamReader(System.in)); for(int i=0; i<8; i++){ arr[i] = read.readLine(); } System.out.println(arr[9]); System.out.println(arr[8]); System.out.println(arr[7]); System.out.println(arr[6]); System.out.println(arr[5]); System.out.println(arr[4]); System.out.println(arr[3]); System.out.println(arr[2]); System.out.println(arr[1]); System.out.println(arr[0]);
