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}
