Java Vector - removeElementAt() Method

The java.util.Vector.removeElementAt() method is used to delete the element at the specified position in the vector. It shifts any subsequent elements to the left by subtracting one from their indices. Every removal of element results into reducing the vector size by one unless the vector is empty.

Syntax

public void removeElementAt(int index)

Here, E is the type of element maintained by the container.

Parameters

Return Value

void type.

Exception

Throws IndexOutOfBoundsException, if the index is out of range (index < 0 || index >= size()).

Example:

In the example below, the java.util.Vector.removeElementAt() method is used to delete the element at the specified position in the given vector.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a vector
    Vector<Integer> MyVector = new Vector<Integer>();

    //populating vector
    MyVector.add(10);
    MyVector.add(20);
    MyVector.add(30);
    MyVector.add(40);
    MyVector.add(50);

    //printing vector
    System.out.println("MyVector contains: "+ MyVector);    

    //delete element at index=2
    MyVector.removeElementAt(2);

    //printing vector
    System.out.println("MyVector contains: "+ MyVector);  
  }
}

The output of the above code will be:

MyVector contains: [10, 20, 30, 40, 50]
MyVector contains: [10, 20, 40, 50]
