                               int iter=0;
                               Scanner sc2=new Scanner(System.in).useDelimiter(" ");
	               while(sc2.hasNextInt()){
			monthsArray[iter]=sc2.nextInt();
			iter++;
		}
		for(int k=0;k < monthsArray.length;k++){
			System.out.println(monthsArray[k]);

You can also use StringTokenizer class with delimiter as space.

Well, first of all, you really need to define what you mean by "not working". But if I had to take a guess...

I am assuming that the code doesn't do anything when you type in the one line. The reason for that is because you are scanning stdin, which keeps reading, so you can't depend on the while loop to exit after the single line is read. Your only exit strategy, is if a non-int, followed by a space, is encountered.

Please see following javadoc:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/StringTokenizer.html

This also has an example.

I suppose you are trying to read distinct words, delimited by space from a string input through console. This is also easy. You can use it if its urgent.
