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
