How to get Item in a Vector at a Specific Index in Java - Step by Step Examples

How to get Item in a Vector at a Specific Index in Java ?

Answer

To access an item in a Java Vector at a specific index, you can use the elementAt method or directly access the index using square brackets ([]).

✐ Examples

1 Access Item at Specific Index - Integer Vector

In this example,

We import the necessary classes, including java.util.Vector.
We create a Vector of integers named intVector.
We access an item at a specific index in the integer Vector using the elementAt method and specify the index of the item we want to access.
The integer item at the specified index is returned.
We print the accessed integer item to the console.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        // Create a Vector of integers
        Vector<Integer> intVector = new Vector<>();
        intVector.add(10);
        intVector.add(20);
        intVector.add(30);

        // Access item at index 2 using elementAt method
        int accessedIntItem = intVector.elementAt(2);

        // Print accessed integer item
        System.out.println("Accessed integer item: " + accessedIntItem);
    }
}

Output

Accessed integer item: 30

2 Access Item at Specific Index - String Vector

In this example,

We import the necessary classes, including java.util.Vector.
We create a Vector of strings named strVector.
We access an item at a specific index in the string Vector using square brackets ([]) and specify the index of the item we want to access.
The string item at the specified index is returned.
We print the accessed string item to the console.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        // Create a Vector of strings
        Vector<String> strVector = new Vector<>();
        strVector.add("apple");
        strVector.add("banana");
        strVector.add("cherry");

        // Access item at index 2 using square brackets
        String accessedStrItem = strVector.get(2);

        // Print accessed string item
        System.out.println("Accessed string item: " + accessedStrItem);
    }
}

Output

Accessed string item: cherry
