It does not generally work the way you might be
thinking, so I will explain.

- people here will not provide you with the answer, though
they may be willing to help.
- It is best to supply some code (even code that does not
compile) and a single question.
- the best group for beginner questions can be found here..
<http://www.physci.org/codes/javafaq.jsp#cljh>
- if you have not done it already, do a 'HelloWorld' program.

Example :

yourString.replace(Integer.toString(yourNumber),  '\n' +
Integer.toString(yourNumber));

Be careful that you're not trying to replace number 14 if numbers such as
144 are also in there. If the numbers are seperated by delimiters make sure
you add those to the search expression.

All that said, this is very basic functionality easily found in the Java
docs, you may wanna consider browsing that before you post questions here.
Just a thought ;)
