Vector Class removeElementAt() method

• removeElementAt() method is available in java.util package.
• removeElementAt() method is used to remove the element that exists at the given indices from this Vector.
• removeElementAt() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• removeElementAt() method may throw an exception at the time of removing an element.
  ArrayIndexOutOfBoundsException: This exception may throw when the given parameter is not in a range.

Syntax:

    public void removeElementAt(int indices);

Parameter(s):

• int indices – represents the position of the removed element.

Return value:

The return type of the method is void, it returns nothing.

Example:

// Java program to demonstrate the example 
// of void removeElementAt(int indices) method 
// of Vector 

import java.util.*;

public class RemoveElementAtOfVector {
 public static void main(String[] args) {
  // Instantiates a Vector object  with
  // initial capacity of "10"
  Vector < String > v = new Vector < String > (10);

  // By using add() method is to add the
  // elements in this v
  v.add("C");
  v.add("C++");
  v.add("JAVA");

  // Display Vector 
  System.out.println("v: " + v);

  // By using removeElementAt(2) method
  // is to remove the element at the given
  // indices
  v.removeElementAt(2);

  // Display updated vector
  System.out.println("v.removeElementAt(2): " + v);
 }
}

Output

v: [C, C++, JAVA]
v.removeElementAt(2): [C, C++]
