To Demonstrate a Three-Dimensional Array

Here is a Java Program to Demonstrate a three-dimensional array

class threeDMatrix {
  public static void main(String args[]) {
    int threeD[][][] = new int[3][4][5];
    int i, j, k;
    
    for(i=0; i<3; i++) 
      for(j=0; j<4; j++)
        for(k=0; k<5; k++)
        threeD[i][j][k] = i * j * k;

    for(i=0; i<3; i++) {
      for(j=0; j<4; j++) {
        for(k=0; k<5; k++) 
          System.out.print(threeD[i][j][k] + " "); 
        System.out.println();
      }
      System.out.println();
    }
  }
}
