Extract information from array

Question

I am having a array like String[] selectedJobs = {"job,1","job,2", "Job2,1", "job3,1"};

I want to extract information like

Job -> 1,2 Job2 -> 1 Job3 -> 1 Map<String, List<String>> jobs = new HashMap<String, List<String>>();

and I want to store each job with corresponding list of integers in map.

How to do this ?

split the 1st string on "," -> "job", "1"
check there is a "job" key in the map, if not create it and put a new arraylist for that key
add "1" to the arraylist
loop

Thanks. I blocked but your idea "check there is a "job" key in the map, if not create it and put a new arraylist for that key" cleared my error. It is working fine.

What have you tried? The algorithm shouldn't be tricky: Go through your array, split on "," for each String, and put it in the HashMap you describe.
