Vector : removeElementAt : Remove Element at Particular position

public synchronized void removeElementAt(int index)

Deletes the component at the specified index. After deletion size of the vector is decreased by 1.

import java.util.*;

class VectorRemoveElementAt{
 public static void main(String args[]){
  Vector<Integer> myVector;
  
  myVector = new Vector<> ();
  
  /*Add Elements to myVector*/
  myVector.add(10);
  myVector.add(11);
  myVector.add(12);
  myVector.add(10);
  myVector.add(10);
  
  System.out.println("Elements in myVector ");
  System.out.println(myVector);
  
  System.out.println("\nRemove the element at index 0");
  myVector.removeElementAt(0);
  System.out.println("Elements in myVector ");
  System.out.println(myVector); 
 }
}

Output

Elements in myVector
[10, 11, 12, 10, 10]

Remove the element at index 0
Elements in myVector
[11, 12, 10, 10]

1. Throws ArrayIndexOutOfBoundsException if the index is out of range

import java.util.*;

class VectorRemoveElementAtIndexOut{
 public static void main(String args[]){
  Vector<Integer> myVector;
  
  myVector = new Vector<> ();
  
  /*Add Elements to myVector*/
  myVector.add(10);
  myVector.add(11);
  myVector.add(12);
  myVector.add(10);
  myVector.add(10);
  
  System.out.println("Elements in myVector ");
  System.out.println(myVector);
  
  System.out.println("\nRemove the element at index 6");
  myVector.removeElementAt(6);
  System.out.println("Elements in myVector ");
  System.out.println(myVector); 
 }
}

Output

Elements in myVector
[10, 11, 12, 10, 10]

Remove the element at index 6
