  • remove(int index)

    The java.util.vector.remove(int index) method is used to remove an element from a Vector from a specific position or index.

    Syntax:

    Vector.remove(int index)

    Parameters: This method accepts a mandatory parameter index is of integer data type and specifies the position of the element to be removed from the Vector.

    Return Value: This method returns the element that has just been removed from the vector.

    Below program illustrate the Java.util.Vector.remove(int index) method:




    // Java code to illustrate remove() when position of
    // element is passed as parameter
    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");
      
            // Output the Vector
            System.out.println("Vector: " + vec_tor);
      
            // Remove the element using remove()
            String rem_ele = vec_tor.remove(4);
      
            // Print the removed element
            System.out.println("Removed element: " + rem_ele);
      
            // Print the final Vector
            System.out.println("Final Vector: " + vec_tor);
        }
    } 

    

    

    
                        
    

    

    

    

    
Output:
    

    Vector: [Geeks, for, Geeks, 10, 20]
Removed element: 20
Final Vector: [Geeks, for, Geeks, 10]

    remove(Object o)
    

    The java.util.vector.remove(Object o) method is used to remove any particular element from the Vector.
    

    Syntax:
    

    Vector.remove(Object o)
    

    Parameters: This method accepts a mandatory parameter o is of the object type of Vector and specifies the element to be removed from the Vector.
    

    Return Value: Returns True if the specified element is found and removed from the Vector, else False.

Vector is similar to arrays but is growable also, or we can say no fixed size is required. Previously vector was a part of legacy classes but now it is part of Collections. It also implements a List interface, so we can use any method of list interface on vectors also.

How to Remove Duplicate Elements from the Vector in Java?

                
Using LinkedHashSet and TreeSet, duplicate elements are removed. Because the LinkedHashSet and TreeSet do not accept duplicate elements. Example: Input : vector = [1, 2, 3, 4, 2, 4] Output: vector = [1, 2, 3, 4] Input : vector = [a, b, a, c, d, a] Output: vector = [a, b, c, d]Approach 1: Using LinkedHashSet LinkedHashSet does not accept duplicate e
