Question about the task

Resolved

Hi guys, I thought I understood the conditions, but definitely, I don't or the author made it unclear on purpose. My code is assigning values of firstArray to the resultArray, then it's assigning values of the second one, precisely in accordance with the task conditions. Please, help!

Implement the main(String[]) method, which needs to copy the contents of the firstArray and secondArray arrays into one resultArray array.
The firstArray array must be at the beginning of the new resultArray array, followed by the secondArray array.

Requirements:

The Solution class must have a public static int[] firstArray variable initialized with an array with 10 values.
The Solution class must have a public static int[] secondArray variable initialized with an array with 10 values.
The Solution class must have a public static int[] resultArray variable.
Implement the main(String[]) method in accordance with the task conditions.

package en.codegym.task.pro.task05.task0504; /* Combining arrays */ public class Solution { public static int[] firstArray = new int[]{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}; public static int[] secondArray = new int[]{10, 11, 12, 13, 14, 15, 16, 17, 18, 19}; public static int[] resultArray; public static void main(String[] args) { int[] resultArray = new int[firstArray.length + secondArray.length]; int index = firstArray.length; for (int i = 0; i < firstArray.length; i++) { resultArray[i] = firstArray[i]; } for (int i = 0; i < secondArray.length; i++) { resultArray[index] = secondArray[i]; index++; } for (int j = 0; j < resultArray.length; j++) { System.out.print(resultArray[j] + ", "); } } } // public static int[] result(int[] a, int[] b) { // // int[] result = new int[a.length + b.length]; // int index = a.length; // for (int i = 0; i < a.length; i++) { // result[i] = a[i]; // } // for (int i = 0; i < b.length; i++) { // result[index] = b[i]; // index++; // } // return result; // }

Have you tried without output as this is not asked?

It's not asked, but it was implemented by default, and the task looked like this in the beginning :

public class Solution {
    public static int[] firstArray = new int[]{0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
    public static int[] secondArray = new int[]{10, 11, 12, 13, 14, 15, 16, 17, 18, 19};
    public static int[] resultArray;

    public static void main(String[] args) {

  /write your code

        for (int j = 0; j < resultArray.length; j++) {
            System.out.print(resultArray[j] + ", ");
        }
    }

solution

Was resultArray already implemented on line 10? If that is the case then the code you wrote should not make and initialize a new resultArray variable (line 13)

Thanks, Mate, that was the case. Solved now.
