Multi Dimes Ional Array

The document provides examples of Java programs demonstrating the use of multi-dimensional arrays, including two-dimensional and three-dimensional arrays. It covers array initialization, assignment of values, and printing the arrays. The examples illustrate how to access specific elements within these arrays.

Java Multi-Dimensional Arrays

// Java Program to Demonstrate

// Multi Dimensional Array

import java.io.*;

public class Main {

public static void main(String[] args){

int[][] arr = new int[10][20];

arr[0][0] = 1;

System.out.println("arr[0][0] = " + arr[0][0]);

// Java Program to demonstrate the use of

// Two Dimensional Array

import java.io.*;

class Main {

public static void main(String[] args){


// Array Intialised and Assigned

int[][] arr = { { 1, 2 }, { 3, 4 } };

// Printing the Array

for (int i = 0; i < 2; i++){

for (int j = 0; j < 2; j++)

System.out.print(arr[i][j]+" ");

System.out.println();

// Java Program to demonstrate the use of

// Two Dimensional Array

public class TwoDArray {

public static void main(String[] args) {

// Row and Columns in Array

int n = 2;

int m = 2;

// Array declared and initialized

int[][] arr = new int[n][m];

int it = 1;

// Assigning the values to array

for (int i = 0; i < n; i++) {

for (int j = 0; j < m; j++) {


arr[i][j] = it;

it++;

// Printing the Array

for (int i = 0; i < n; i++) {

for (int j = 0; j < m; j++)

System.out.print(arr[i][j] + " ");

System.out.println();

Example

// Java Program to Demonstrate

// Three Dimensional Array

import java.io.*;

class Main {

public static void main(String[] args){

// Array Created and Initialized

int[][][] arr = { { { 1, 2 }, { 3, 4 } }, { { 5, 6 }, { 7, 8 } } };

// Defining the x,y,z in Multi

// Dimensional Array

int n = arr.length;

int m = arr[0].length;
int o = arr[0][0].length;

// Printing the Array

for (int i = 0; i < n; i++) {

for (int j = 0; j < m; j++){

for(int k=0; k < o; k++)

System.out.print(arr[i][j][k] + " ");

System.out.println();

System.out.println();

Example of three dimensional array

// Java Program to Demonstrate Accessing

// Three Dimensional Array by Index

import java.io.*;

class GFG {

public static void main(String[] args){

// Creating an Array

int[][][] arr = { { { 1, 2 }, { 3, 4 } },

{ { 5, 6 }, { 7, 8 } } };

// Printing array at index 0 , 0 , 0

System.out.println("arr[0][0][0] = " + arr[0][0][0]);
