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]
