public class HashTableTest extends MIDlet

	public HashTableTest() 
	{

		ht.put("0",new Integer(55)) ;
		ht.put("77",new Integer(100)) ;
		
		System.out.println("Value of key 19 is "+ht.get("19")) ;
		
		Enumeration e = ht.elements() ;
		while(e.hasMoreElements())
		{
			System.out.println(e.nextElement()) ;
