Question

Use a two-dimensional, multi-dimensional array and pass it to a method and receive it back. You will
create the array, add data, send it to a method to be updated and return it.

public class MultiDimensionArray ( public static void main(String[] args) { // Initialize 2-dimensional array int[][] origTwoDimArr = { (15, 25, 17, 24}, {6, 85, 12, 62), (18, 22, 96, 5} }; // See the size of the array System.out.println("Rows- System.out.println("Columns *+ origTwoDinArr.length); using the index-origTwoDimArr[0].length); System.out.println("Columns using the 1 index - + origTwoDinArr[1].length "\n"); // Print out original content of array System.out.println("Original contents of 2-dimensional array"); for (int a = 0; ac origTwoDimArr.length; a++) { } for (int b = 0; b < origTwoDimArr[0].length; b++) { System.out.print(origTwoDimArr[a][b] + (b < 2?",":"")); // If last index, don't print comma } System.out.print("\n"); //newTwoDimArr // Update the array origTwoDinArr arrayMultiplier (origTwoDimArr); // Update the array - arrayMultiplier(origTwoDimArr); // Print out the updated content of the array System.out.println("\nNew contents of 2-dimensional array"); for (int c = 0; c < origTwoDimArr.length; c++) { for (int d - 8; d < origTwoDimArr[0].length; d++) { } System.out.print(origTwoDimArr[c][d] + (c < 2?",":"")); System.out.print("\n"); } // This method will iterate through a two-dimensional array and // update each cell by multiplying it by 10 and then returning it private static int[][] arrayMultiplier (int[][] anArr) { System.out.println("\nInside the multiplier method"); // Create an array to match the one that was passed int[][] tempArr- new int [anArr.length] [anArr [0].length]; // Use a nested loop to iterate through the array for (int x = 0; x<anArr.length; x++) for (int y = 0; y< anArr[0].length; y++) { tempArr[x][y] - anArr[x][y] 18; System.out.println("Leaving the multiplier method"); return tempArn;
