How to create a Vector of Empty Vectors in Java - Step by Step Examples

How to create a Vector of Empty Vectors in Java ?

Answer

To create a vector of empty vectors in Java using java.util.Vector, you can initialize a Vector object and populate it with empty vectors using a for loop.

✐ Examples

1 Create Vector of Empty Vectors using for Loop

In this example,

We import the java.util.Vector class to use the Vector data structure.
We create a Vector object named emptyVectorList to store empty vectors.
We specify the number of empty vectors to create (e.g., 5).
We use a for loop to iterate a specific number of times.
Within each iteration, we add an empty vector to the Vector.
The Vector emptyVectorList now contains the desired number of empty vectors.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Vector<Integer>> emptyVectorList = new Vector<>();
        int numEmptyVectors = 5;

        for (int i = 0; i < numEmptyVectors; i++) {
            emptyVectorList.add(new Vector<>());
        }

        System.out.println(emptyVectorList);
    }
}

Output

[[], [], [], [], []]

2 Create Vector of Empty Vectors using Enhanced for Loop

In this example,

We import the java.util.Vector class to use the Vector data structure.
We create a Vector object named emptyVectorList to store empty vectors.
We specify the number of empty vectors to create (e.g., 5).
We use an enhanced for loop to iterate a specific number of times.
Within each iteration, we add an empty vector to the Vector.
The Vector emptyVectorList now contains the desired number of empty vectors.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Vector<Integer>> emptyVectorList = new Vector<>();
        int numEmptyVectors = 5;

        for (int i = 0; i < numEmptyVectors; i++) {
            emptyVectorList.add(new Vector<>());
        }

        for (Vector<Integer> vec : emptyVectorList) {
            System.out.println(vec);
        }
    }
}

Output

[ ]
