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

How to create a Vector of Integers in Java ?

Answer

To create a vector of integers in Java using java.util.Vector, you can initialize a Vector object and use the add method to add integers to the vector.

✐ Examples

1 Create Vector of Integers using java.util.Vector

In this example,

We import the java.util.Vector class to use the Vector data structure.
We create a Vector object named intVector to store integers.
We use the add method of Vector to add integers one by one to the vector.
After adding all integers, the Vector contains the desired sequence of integers.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> intVector = new Vector<>();
        intVector.add(1);
        intVector.add(2);
        intVector.add(3);
        intVector.add(4);
        intVector.add(5);

        System.out.println(intVector);
    }
}

Output

[1, 2, 3, 4, 5]

2 Create Vector of Integers 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 intVector to store integers.
We use the add method of Vector to add integers one by one to the vector.
We use an enhanced for loop to iterate through the Vector and print each integer.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> intVector = new Vector<>();
        intVector.add(1);
        intVector.add(2);
        intVector.add(3);
        intVector.add(4);
        intVector.add(5);

        for (int num : intVector) {
            System.out.print(num + " ");
        }
        System.out.println();
    }
}

Output

1 2 3 4 5
