How to split a string without losing any word in JAVA

I was using eclipse for java.

I want to split an input line without losing any char.

For example input line is:

MAC 4 USD7MAIR 2014 USD1111IMAC 123 USD232MPRO 2-0-1-5

And the output should be :

MAC 4 USD7,MAIR 2014 USD1111,IMAC 123 USD232,MPRO 2-0-1-5

(If I split with "M" or etc. the char "M" itself will be remove.)

What should I do ?
