Vector Class elementAt() method

• elementAt() method is available in java.util package.
• elementAt() method is used to return the element at the given indices of this Vector.
• elementAt() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• elementAt() method may throw an exception at the time of returning the element.
  ArrayIndexOutOfBoundsException: This exception may throw when the given index is less than 0 or greater than the current size.

Syntax:

    public Object elementAt(int index);

Parameter(s):

• int index – represents the position of the returned element.

Return value:

The return type of the method is Object, it returns the object of the given index.

Example:

// Java program to demonstrate the example 
// of Object elementAt(int indices) method 
// of Vector 

import java.util.*;

public class ElementAtOfVector {
    public static void main(String[] args) {
        // Instantiates a Vector object  with
        // initial capacity of "10"
        Vector < String > v = new Vector < String > (10);

        // By using add() method is to add the
        // elements in this v
        v.add("C");
        v.add("C++");
        v.add("JAVA");

        // Display Vector
        System.out.println("v: " + v);

        // By using elementAt(1) method is to
        // return the element at the given indices
        // "1"
        Object ele = v.elementAt(1);

        // Display returned element at the
        // given indices
        System.out.println("v.elementAt(1): " + ele);
    }
}

Output

v: [C, C++, JAVA]
v.elementAt(1): C++
