Vector remove() Method in Java

• 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.

  Below program illustrate the Java.util.Vector.remove(Object O) method:

  // Java code to illustrate remove() 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");
  
          // Output the Vector
          System.out.println("Vector: " + vec_tor);
  
          // Remove the head using remove()
          Boolean rem_ele;
  
          rem_ele = vec_tor.remove("Geeks");
          // Print the removed element
          if (rem_ele)
              System.out.println("Geeks"
                                 + " found and removed.");
          else
              System.out.println("Geeks"
                                 + " not found or removed.");
  
          rem_ele = vec_tor.remove("500");
          // Print the removed element
          if (rem_ele)
              System.out.println("500"
                                 + " found and removed.");
          else
              System.out.println("500"
                                 + " not found or removed.");
  
          // Print the final Vector
          System.out.println("Final Vector: " + vec_tor);
      }
  }
  Output:

  Vector: [Geeks, for, Geeks, 10, 20]
  Geeks found and removed.
  500 not found or removed.
  Final Vector: [for, Geeks, 10, 20]
