Three Dimension Array in Java Language
In this tutorial, we can get to know about Three Dimension Array in Java Language.
In the Java programming language, an array is a fixed sequential collection of an element of the same data types. An array can be used to represent a list of numbers(int) or names (string) or other data type of similar elements. It is one of the ways to group similar type of data within the single variable name.
Three types of arrays in Java programming language
3. Three-dimensional array
Three-dimensional array is the collection of two-dimensional arrays in Java programming language. Three-dimensional array is also called the multidimensional array.
Declaration of the three dimensional Array
Syntax
date_type[][][] arrayname;----1 or date_type [][][]arrayname;----2 or date_type arrayname [][][] ;----3
we can choose any one method
Explanation of Three dimensional Array declaration
int [][][]array;
Forming of three dimension array
Syntax
data_type[][][]array_name=new data_type;
Example
int array[][][]=new int[2][3][3];
How to find the index of 3 D Array
Above diagram describes how to find index of three dimension array. Every array has two index 0 to 1
so we can find index follows
array_name[0][0][0] //first index
array_name[0][0][1] //second index
array_name[0][1][0] //third index
array_name[0][1][1] //forth index
array_name[1][0][0] //fifth index
array_name[1][0][1] //sixthindex
array_name[1][1][0] //seven index
array_name[1][1][1] //eight index
How to initialize a 3d array in Java
Method 1
Syntax
array_name[index_1][index_2][index_3]=value;
Example
arr[0][0][0]=45; //initialize first elements of 3 d array
we can initialize every index, like this
Method 2
int[][][] arr{
{
{34,67,43},
{576,697,423},
{576,697,423}
},
{
{39,47,33},
{376,987,453},
{57,69,42}
},
program 1
class threedarrayex{
public static void main(String args[])
{
int[][][]marks; //declaration of array
marks=new int[2][2][2];//initiation of array
//initiate elements
marks[0][0][0]=25;
marks[0][0][1]=15;
marks[0][1][0]=20;
marks[0][1][1]=05;
marks[1][0][0]=10;
marks[1][0][1]=13;
marks[1][1][0]=12;
marks[1][1][1]=30;
//Display elements from array
System.out.println(marks[0][0][0]);
System.out.println(marks[0][0][1]);
System.out.println(marks[0][1][0]);
System.out.println(marks[0][1][1]);
System.out.println(marks[1][0][0]);
System.out.println(marks[1][0][1]);
System.out.println(marks[1][1][0]);
System.out.println(marks[1][1][1]);
}
}
When the above code is compiled and executed, it will produce the following results
25 15 20 5 10 13 12 30
Display the element of the array using nested for loop in Java
Program 1
class threedarrayex1{

marks[0][1][0]=20;
marks[0][1][1]=05;
marks[1][0][0]=10;
marks[1][0][1]=13;
marks[1][1][0]=12;
marks[1][1][1]=30;
//Display elements from array using for loop
for(int i=0; i<=1; i++){
for(int j=0; j<=1; j++){
for(int k=0; k<=1; k++){
System.out.println(marks[i][j][k]);
