How to create a Three Dimensional Vector in Java ?

Answer

To create a three-dimensional vector in Java using java.util.Vector, you can use nested Vector objects.

✐ Examples

1 Create a Numeric Three-Dimensional Vector

In this example,

We import the Vector class from java.util package.
We declare a Vector of Vectors of Vectors, representing a three-dimensional structure.
We specify the dimensions of the Vector using nested Vector objects.
We assign values to the elements of the Vector.

Java Program

import java.util.Vector;

class Main {
    public static void main(String[] args) {
        // Step 1: Create a numeric three-dimensional vector
        Vector<Vector<Vector<Integer>>> threeDimensionalVector = new Vector<>();

        // Step 2: Populate the vector
        for (int i = 0; i < 3; i++) {
            Vector<Vector<Integer>> layer = new Vector<>();
            for (int j = 0; j < 3; j++) {
                Vector<Integer> row = new Vector<>();
                for (int k = 0; k < 3; k++) {
                    row.add(i * 9 + j * 3 + k + 1);
                }
                layer.add(row);
            }
            threeDimensionalVector.add(layer);
        }

        // Step 3: Print the vector
        for (Vector<Vector<Integer>> layer : threeDimensionalVector) {
            for (Vector<Integer> row : layer) {
                System.out.println(row);
            }
            System.out.println();
        }
    }
}

Output

[1, 2, 3]
[4, 5, 6]
[7, 8, 9]

[10, 11, 12]
[13, 14, 15]
[16, 17, 18]

[19, 20, 21]
[22, 23, 24]
[25, 26, 27]

2 Create a String Three-Dimensional Vector

In this example,

We import the Vector class from java.util package.
We declare a Vector of Vectors of Vectors, representing a three-dimensional structure.
We specify the dimensions of the Vector using nested Vector objects.
We assign values to the elements of the Vector.

Java Program

import java.util.Vector;

class Main {
    public static void main(String[] args) {
        // Step 1: Create a string three-dimensional vector
        Vector<Vector<Vector<String>>> threeDimensionalVector = new Vector<>();

        // Step 2: Populate the vector
        String alphabet = "abcdefghijklmnopqrstuvwxyz!";
        for (int i = 0; i < 3; i++) {
            Vector<Vector<String>> layer = new Vector<>();
            for (int j = 0; j < 3; j++) {
                Vector<String> row = new Vector<>();
                for (int k = 0; k < 3; k++) {
                    row.add(String.valueOf(alphabet.charAt(i * 9 + j * 3 + k)));
                }
                layer.add(row);
            }
            threeDimensionalVector.add(layer);
        }

        // Step 3: Print the vector
        for (Vector<Vector<String>> layer : threeDimensionalVector) {
            for (Vector<String> row : layer) {
                System.out.println(row);
            }
            System.out.println();
        }
    }
}

Output

[a, b, c]
[d, e, f]
[g, h, i]

[j, k, l]
[m, n, o]
[p, q, r]

[s, t, u]
[v, w, x]
[y, z, !]
