Vector : trimToSize : Trim Size

public synchronized void trimToSize()

Trims the capacity of this vector to be the vector's current size.

import java.util.*;

class VectorTrimSize{
 public static void main(String args[]){
  Vector<Integer> myVector;
  myVector = new Vector<> (15, 5);
  
  myVector.add(10);
  
  System.out.print("Capacity of myVector is ");
  System.out.println(myVector.capacity());
  System.out.print("size of myVector is ");
  System.out.println(myVector.size());
  
  myVector.trimToSize();
  
  System.out.println("\nTrimming to Size");
  System.out.print("\nCapacity of myVector is ");
  System.out.println(myVector.capacity());
 }
}

Output

Capacity of myVector is 15
size of myVector is 1

Trimming to Size

Capacity of myVector is 1
