Vector elementAt() Method in Java
The java.util.vector.elementAt(int pos) method is used to fetch or retrieve an element at a specific index from a Vector.
Syntax:
Vector.elementAt(int pos)
Parameters: This method accepts a mandatory parameter pos of integer data type that specifies the position or index of the element to be fetched from the Vector.
Return Value: The method returns the element present at the position specified by the parameter pos.
Below programs illustrate the Java.util.Vector.get() method:
Program 1:
// Java code to illustrate elementAt() method import java.util.Vector; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<String> vec_tor = new Vector<String>(); // Use add() method to add elements in the Vector vec_tor.add("Geeks"); vec_tor.add("for"); vec_tor.add("Geeks"); vec_tor.add("10"); vec_tor.add("20"); // Displaying the Vector System.out.println("Vector: " + vec_tor); // Fetching the specific element from the Vector System.out.println("The element is: " + vec_tor.elementAt(3)); } } |

Output:
Vector: [Geeks, for, Geeks, 10, 20] The element is: 10
Program 2:
// Java code to illustrate elementAt() method import java.util.Vector; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<Integer> vec_tor = new Vector<Integer>(); // Use add() method to add elements in the Vector vec_tor.add(1); vec_tor.add(2); vec_tor.add(3); vec_tor.add(4); vec_tor.add(5); // Displaying the Vector System.out.println("Vector: " + vec_tor); // Fetching the specific element from the Vector System.out.println("The element is: " + vec_tor.elementAt(1)); } } |

Output:
Vector: [1, 2, 3, 4, 5] The element is: 2
