How to Copy a Vector in Java ?

Answer

In Java using java.util.Vector, you can copy a vector by creating a new Vector object and adding all elements from the original vector to the new one.

✐ Examples

1 Copy a Vector using Constructor

In this example,

We create a Vector named originalVector with some values.
We create a new Vector named copiedVector and initialize it with the elements of originalVector using the constructor.
Any modifications made to originalVector will not affect copiedVector.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> originalVector = new Vector<>();
        originalVector.add(1);
        originalVector.add(2);
        originalVector.add(3);
        originalVector.add(4);
        originalVector.add(5);
        Vector<Integer> copiedVector = new Vector<>(originalVector);
        System.out.println("Original vector: " + originalVector);
        System.out.println("Copied vector: " + copiedVector);
    }
}

Output

Original vector: [1, 2, 3, 4, 5]
Copied vector: [1, 2, 3, 4, 5]

2 Copy a Vector using addAll() Method

In this example,

We create a Vector named originalVector with some values.
We create a new Vector named copiedVector.
We use the addAll() method to add all elements from originalVector to copiedVector.
Any modifications made to originalVector will not affect copiedVector.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> originalVector = new Vector<>();
        originalVector.add(1);
        originalVector.add(2);
        originalVector.add(3);
        originalVector.add(4);
        originalVector.add(5);
        Vector<Integer> copiedVector = new Vector<>();
        copiedVector.addAll(originalVector);
        System.out.println("Original vector: " + originalVector);
        System.out.println("Copied vector: " + copiedVector);
    }
}

Output

Original vector: [1, 2, 3, 4, 5]
Copied vector: [1, 2, 3, 4, 5]
