Question

I am storting the values of SELECT QUERY in a map , with combined month and year (Mon YY) as key.
I used order by date in my query. Its working fine, but when i display the value of a map, its in random order.

Is there any way to get the first inserted element first ( like queue)?

  Inserting element
       Dec 2011     REC     332     12      
       Dec 2011     WER     12      12      
       Dec 2012     QA      212     12 

  Displaying value   
            Inner Key :Dec 2012
            QA
            212
            12
            Inner Key :Dec 2011
            REC
            332
            12
            WER
            12
            12

I need the values in ascending order

Answer 1

Use a LinkedHashMap, which preserves insertion order.
