Hashtable toString Example
Hashtable class toString example.public String toString() Returns a string representation of this Hashtable object in the form of a set of entries, enclosed in braces and separated by the ASCII characters ", " (comma and space). Each entry is rendered as the key, an equals sign =, and the associated element, where the toString method is used to convert the key and element to strings.
Here is the code
/**

* A class repersenting use to clear method
* of HashMap class in java.util package
* version 19 May 2008

*/
import java.util.*;
public class ToString {
public static void main(String args[]) {
Hashtable table = new Hashtable();
//Put value into the table
table.put(1, "A");
table.put(2, "B");
table.put(3, "C");
table.put(4, "D");
//a string representation of this Hashtable
//object in the form of a set of entries
String str=table.toString();
System.out.println("table :" + str);
}
