	public static void main(String args[])
	{
			String sentence;
			char input;

			System.out.println("Please enter a sentense");
			try {

					sentence = temp.readLine();
					for (int i=0; i<=sentence.length()-1; i++)
					{
							input = sentence.charAt(i);

							Node node = new Node(new Character(input), list.getFirstNode());
							/** function same as
									Node node = new Node();
									node.setElement(new Character(input));
									node.setNextNode(list.getFirstNode()); **/

							list.insertNode(node);
					}

					System.out.println("The Reverse is:");
					list.printAllNodeInReverse();
