The java.util.vector.get() method is used to fetch or retrieve an element at a specific index from a Vector.
Syntax:
Vector.get(int index)
Parameters: This method accepts a mandatory parameter index which is of integer data type. It 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 index.
Below programs illustrate the Java.util.Vector.get() method:
Program 1:
Java
// Java code to illustrate get() methodimport java.util.*;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.get(2)); }} |
Output:
Vector: [Geeks, for, Geeks, 10, 20] The element is: Geeks
Program 2:
Java
// Java code to illustrate get() methodimport 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("1"); vec_tor.add("2"); vec_tor.add("3"); 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.get(4)); }} |
Output:
Vector: [1, 2, 3, 10, 20] The element is: 20
Time complexity: O(n), // n is the number of elements in the vector.
Auxiliary space: O(n)
