The Hashtable class overrides the toString() method of the Object class
public String toString()
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"); System.out.println(table); } }
{key3=value3, key2=value2, key1=value1}
