Split many single character with regex (java)

Question

I've got two strings: "EEFFE" and "EEFFFFFFFFFE", is there any regular expression in java such that when I use split get the following array in both strings?: {"EE","E"}.

Answer 1

Alternate solution with a slightly different result:

String a = "EEFFE"; 
String b = a.replaceAll("F+", "");

Answer 2

The regex you are looking for is just "F+".

String[] whatINeed = s.split("F+")
