		ArrayList words = new ArrayList();
		Scanner in = new Scanner(System.in);

		String text = in.nextLine();		
				
		for(i = 0; i < text.length(); i++) {
			
			if(text.charAt(i) == ' ') {	
				
				// If space found then consider it as word and add it to ArrayList
				words.add(text.substring(index, i));
				index = i + 1;
			}
		}
		words.add(text.substring(index)); // Adding last word
		
		System.out.println("\nWords in the sentence are....");
		
		for(String s: words) {

		}
