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

How to Convert a Vector of Strings to a Vector of Integers in Java ?

Answer

To convert a vector of strings to a vector of integers in Java using java.util.Vector, you can iterate through the vector and use the `Integer.parseInt()` method to convert each string to an integer.

✐ Examples

1 Convert Vector of Strings to Vector of Integers

In this example,

We create a Vector named strVector containing strings.
We create a new Vector named intVector to store integers.
We iterate through each element of strVector and convert it to an integer using the Integer.parseInt() method.
We add each converted integer to intVector.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<String> strVector = new Vector<>();
        strVector.add("1");
        strVector.add("2");
        strVector.add("3");
        Vector<Integer> intVector = new Vector<>();
        for (String str : strVector) {
            intVector.add(Integer.parseInt(str));
        }
        System.out.println(intVector);
    }
}

Output

[1, 2, 3]
