3D Array

I am having problem understanding the output of the code:

3darrays.java 
public class 3DArrays {
    public static void main(String args[]){
        int threeD[][] = new int[3][4][5];
         int  i, j, k = 0;


        for( i = 0; i<3; i++){
            for ( j = 0; j<4; j++){
                            for( k = 0; k<3; k++) {
                threeD[i][j] [k]= i*j*k;



        for( i = 0; i<3; i++){
            for ( j = 0; j<4; j++){
                            for( k = 0; k<3; k++) {

            System.out.print(threeD[i][j][k] + " ");
            System.out.println();
                    }

System.out.println();

                    }

    }

}

/* as you can see the output is:

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

0 0 0 0 0 0 1 2 3 4 0 2 4 6 8 0 3 6 9 12

0 0 0 0 0 0 2 4 6 8 0 2 4 6 8 0 4 8 12 16 0 6 12 18 24

just explain me the output please */
