How to Join Vectors in Java ?

Answer

In Java, you can join vectors by using the `addAll()` method of the `Vector` class.

✐ Examples

1 Join Vectors using addAll() method

In this example,

We create two vectors, vec1 and vec2, with different elements.
We use the addAll() method to add all elements of vec2 to vec1.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> vec1 = new Vector<>();
        Vector<Integer> vec2 = new Vector<>();

        // Add elements to vec1
        vec1.add(1);
        vec1.add(2);
        vec1.add(3);

        // Add elements to vec2
        vec2.add(4);
        vec2.add(5);
        vec2.add(6);

        // Join vectors using addAll() method
        vec1.addAll(vec2);

        // Print the combined vector
        System.out.println(vec1);
    }
}

Output

[1, 2, 3, 4, 5, 6]

2 Join Vectors of Strings using addAll() method

In this example,

We create two vectors, vec1 and vec2, with different strings.
We use the addAll() method to add all elements of vec2 to vec1.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<String> vec1 = new Vector<>();
        Vector<String> vec2 = new Vector<>();

        // Add elements to vec1
        vec1.add("apple");
        vec1.add("banana");
        vec1.add("orange");

        // Add elements to vec2
        vec2.add("grape");
        vec2.add("kiwi");
        vec2.add("melon");

        // Join vectors using addAll() method
        vec1.addAll(vec2);

        // Print the combined vector
        System.out.println(vec1);
    }
}

Output

[apple, banana, orange, grape, kiwi, melon]
