Example

The following example shows the usage of java.util.Vector.hashCode() method.

package com.tutorialspoint;

import java.util.Vector;

public class VectorDemo {
   public static void main(String[] args) {

      // create an empty Vector vec with an initial capacity of 4      
      Vector<Integer> vec = new Vector<Integer>(4);

      // use add() method to add elements in the vector
      vec.add(4);
      vec.add(3);
      vec.add(2);
      vec.add(1);

      // let us get the hashcode of the vector
      System.out.println("Hash code :"+vec.hashCode());
   }
}

Let us compile and run the above program, this will produce the following result −

Hash code :1045631
