this is the class by which i can get the trackId of the song present in the db.




this is the class to get the trackId of the songs which are currently in the xml file.

now i want to compare those two different trackId and if there is any update in the xml (i.e. entry of the new song with different trackId or deletion of old song) after which trackId will not match each other then change accordingly in DB via sql query through java. please guide me about how can i be able to compare those trackid one by one and make the program further. i also wan to do that in the separate thread class which continously do the same task.

thanks in adavance.

I doubt you will get much help here with a post like that. If you haven't read it, you should probably check out the entries in our HowToAskQuestionsOnJavaRanch (<--click that) FAQ. Generally speaking, overly broad or general "guide me" questions don't work well here.

However, if you have a specific, focused question, you will get more help than you could ever hope for.

well, cant you take trackIds from the hashmap (using keySet()) and compare with the trackIds in list through nested for loops?
