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() method import 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() 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(" 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)
