Vector removeElementAt() Method in Java

The java.util.vector.removeElementAt(int index) method is used to remove an element from a Vector from a specific position or index. In this process the size of the vector is automatically reduced by one and all other elements after the removed element are shifted downwards by one position. 

Syntax:

Vector.removeElementAt(int index)

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

Return Value: This method has void return type. It means it does not return anything. 

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

Vector: [Geeks, for, Geeks, 10, 20]
The initial size is: 5
Final Vector: [Geeks, for, 10, 20]
The final size is: 4

Time complexity: O(n). // n is the size of the vector.
Auxiliary Space: O(1).
