How to Concatenate Two Vectors in Java ?

Answer

To concatenate two vectors in Java using java.util.Vector, you can use the `addAll` method or the `addElement` method.

✐ Examples

1 Concatenate Numeric Vectors using addAll() method

In this example,

We create two Vector objects named vector1 and vector2.
We call the addAll method on vector1, passing vector2 as an argument.
The addAll method adds all elements from vector2 to vector1.
Finally, we print vector1 to standard output.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> vector1 = new Vector<Integer>();
        vector1.add(1);
        vector1.add(2);
        vector1.add(3);
        Vector<Integer> vector2 = new Vector<Integer>();
        vector2.add(4);
        vector2.add(5);
        vector2.add(6);
        vector1.addAll(vector2);
        System.out.println(vector1);
    }
}

Output

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

2 Concatenate Character Vectors using addElement() method

In this example,

We create two Vector objects named vector1 and vector2.
We call the addElement method on vector1 for each element in vector2.
The addElement method adds each element from vector2 to the end of vector1.
Finally, we print vector1 to standard output.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Character> vector1 = new Vector<Character>();
        vector1.add('a');
        vector1.add('b');
        vector1.add('c');
        Vector<Character> vector2 = new Vector<Character>();
        vector2.add('d');
        vector2.add('e');
        vector2.add('f');
        for (char ch : vector2) {
            vector1.addElement(ch);
        }
        System.out.println(vector1);
    }
}

Output

[a, b, c, d, e, f]
