Java Collection, HashSet Exercises: Exercise-6 with Solution

Write a Java program to clone a hash set to another hash set.

Sample Solution:

Java Code:

import java.util.*;

  public class Exercise6 {
  public static void main(String[] args) {
         // Create a empty hash set
     HashSet<String> h_set = new HashSet<String>();
   // use add() method to add values in the hash set
          h_set.add("Red");
          h_set.add("Green");
          h_set.add("Black");
          h_set.add("White");
          h_set.add("Pink");
          h_set.add("Yellow");
    System.out.println("Original Hash Set: " + h_set);
    HashSet <String> new_h_set = new HashSet <String> ();
          new_h_set = (HashSet)h_set.clone();
          System.out.println("Cloned Hash Set: " + new_h_set);         
   }
}

Sample Output:

Note: Exercise6.java uses unchecked or unsafe operations.              
Note: Recompile with -Xlint:unchecked for details.                     
Original Hash Set: [Red, White, Pink, Yellow, Black, Green]            
Cloned Hash Set: [Red, White, Pink, Yellow, Black, Green]
