Question

A programmer at my office made a bit of a retarded database, so I’m stuck with a problem.
I’ve got a String I need to split into 4 parts, so I can read the data from the indexes.

The string I’ve got is this:

aimer|4-28-2-2.mp3=12###

The array I’d like to get back is:

1. aimer
2. 4-28-2-2.mp3
3. 12
4. ###

The Java code I’m currently using:

String assignmentRaw = "aimer|4-28-2-2.mp3=12###";
String[] assignmentSplit = assignmentRaw.split("\\||=");

for(String assignment : assignmentSplit)
    Log.i(ElkeDagApplication.DEBUG_TAG, assignment);

And returns:

1. aimer
2. 4-28-2-2.mp3
3. 12###

Answer 1

If the requirement for the last split is: a digit on the left and # on the right you can do this

String[] assignmentSplit = assignmentRaw.split("\\||=|(?<=\\d)(?=#)");

(?<=\\d) is a lookbehind assertion that checks for a digit on the left

(?=#) is a lookahead assertion that checks for a “#” on the right
