	{
		LinkedHashSet<String> listOfNames = new 
                LinkedHashSet<String>();
		
		listOfNames.add("JAVA");
		listOfNames.add("GOAL");
		listOfNames.add("RAVI");
		listOfNames.add("SITE");
		
		// Before clear() method
		for(String name : listOfNames)
		{
		   System.out.println("Name from list = "+name);
		}
		
		// Removing all the element by clear() method
		listOfNames.clear();
		
		System.out.println("After Clear() method list is 
                empty : "+ listOfNames.isEmpty());
	}
