The Hashtable class provides its own implementation of the clone() method.
import java.util.Hashtable; public class MainClass { public static void main(String[] s) { Hashtable table = new Hashtable(); table.put("key1", "value1"); table.put("key2", "value2"); table.put("key3", "value3"); Hashtable tableCopy = (Hashtable)table.clone(); System.out.println(tableCopy); } }
{key3=value3, key2=value2, key1=value1}
