Three Dimensional Array in java language

In this article, we will discuss the Three Dimensional Array in Java language

Basically, three-dimension array is array of 2d arrays

Before learning Three-dimensional array, you visit and understand in Java one dimension Array and two-dimension Array.

In that chapter, you learned to define ,create and use Three dimension array of primitive data types ( Double, int etc.), String array.

Declaration of the three-dimensional array

Syntex

Three dim array can declare following method

dataType[][][] arrayname; —— 1 or

dataType [][][]arrayname; ——- 2 or

dataType arrayname [][][]; —— 3

you can choose any one method

Example for Three dim array declaration

int [][][] array;

Creation of the three-dimensional array

Syntex

datatype[][][]arrayname=new datatype;

Example of Creation of Three-dimensional array

array=new int[3][3][3];

How to initialize a Three-dimensional array

Using staranded method

Program 1

array[0][0][0]=66;

array[0][0][1]=54;

array[0][0][2]=36;

array[0][1][0]=59;

array[0][1][1]=50;

array[0][1][2]=55;

array[1][0][0]=59;

array[1][1][0]=54;

array[1][1][1]=59;

Example

Program 1

When the above program is executed, it produces the following result

Program 2

Three dimension array – initialized standard method and separate elements from the array using Nested for loop

Retrieve element from Array using nested for loop

When the above program is executed, it produces the following result

346

586

747

673

Program 3

We can retrieve elements from Three dimension array using enhanced for loop

When the above program is executed, it produces the following result

Initialized array during the declaration

Code segment

int[][][] age={{45,34,67,65},

{23,76,58,72},

{15,65,68,90},

};

Program 1

class ArrayWithForThreeDim{
public static void main (String args[]){
int[][][] age={
  {
  {45,34,67},
{23,76,58},
{48,52,69},
  },
  {
{15,65,68},
{25,45,78},
{45,55,68},
  }
};

System.out.print("\ndisplay cell value in an array: \n");
for(int i=0; i<=1; i++){
   for(int j=0; j<=2; j++){
   for(int k=0; k<=2; k++){
      System.out.print("\ndisplay Element index["+i+"]["+j+"]["+k+"]: "+age[i][j][k] );
}
}
}
}
}

When the above program is executed, it produces the following result

Initializing and display elements using loops

Using for loop

import java.util.Scanner;
class ThreeDimArray{
public static void main(String args[]){
  int i,j,k;
Scanner scan=new Scanner(System.in);
int arr[][][]=new int[2][2][3];//array declaration 
System.out.print("\nEnter the Element to three dim array: \n"); 
for(i=0; i<2; i++){ 
for(j=0; j<2; j++){ 
for(k=0; k<3; k++){ 
arr[i][j][k]=scan.nextInt(); 
} 
} 
}
System.out.print("\ndisplay Element in an array: \n"); 

for(i=0; i<2; i++){ 
for(j=0; j<2; j++){ 
for(k=0; k<3; k++){
System.out.print("\ndisplay Element["+i+"]["+j+"]["+k+"]:"+arr[i][j][k] ); 
}
 }
 }
}
 }

When the above program is executed, it produces the following result

output

Using while loop

import java.util.Scanner;
class ThreeDimArray1{
public static void main(String args[]){
  int i,j,k;
Scanner scan=new Scanner(System.in);
int arr[][][]=new int[2][2][3];//array declaration 
System.out.print("\nEnter the Element to three dim array: \n"); 
i=0;
while(i<2){ 
j=0; 
while(j<2){ 
k=0;
while(k<3){ 
arr[i][j][k]=scan.nextInt(); 
 k++;
} 
 j++;
} 
 i++;
}
System.out.print("\ndisplay Element in an array: \n"); 
i=0;
while(i<2){ 
j=0;
while(j<2){ 
k=0;
while(k<3){
System.out.print("\ndisplay Element["+i+"]["+j+"]["+k+"]:"+arr[i][j][k] ); 
 k++;
}
 j++;
 }
  i++;
 }
}
 }

When the above program is executed, it produces the following result

Output

|Using do-while loop

class ThreeDimArray2{
public static void main(String args[]){
  int i,j,k;
Scanner scan=new Scanner(System.in);
int arr[][][]=new int[2][2][3];//array declaration 
System.out.print("\nEnter the Element to three dim array: \n"); 
i=0;
do{ 
j=0; 
do{ 
k=0;
do{ 
arr[i][j][k]=scan.nextInt(); 
 k++;
} while(k<3);
 j++;
} while(j<2);
 i++;
}while(i<2);
System.out.print("\ndisplay Element in an array: \n"); 
i=0;
do{ 
j=0;
do{ 
k=0;
do{
System.out.print("\ndisplay Element["+i+"]["+j+"]["+k+"]:"+arr[i][j][k] ); 
 k++;
}while(k<3);
 j++;
 }while(j<2);
  i++;
 }while(i<2);
}
 }

When the above program is executed, it produces the following result

Output
