You can add stuff to the maps that they contain, but there are still only two entries in `results`itself Try printing the contents of all your maps to see what's going on - at first sight I think your code is doing what you wanted.

I thought about using a Map, so I did some looking around and found out that LinkedHashMaps are the only type of Map that stay in Order when you do something with them. I could use two arrays, but I'm sure theres something better to use. … Re: Should I use a LinkedHashMap for this? 8 Years Ago by JamesCherrill What's the requirement for keeping them ordered? Re: Should I use a LinkedHashMap for this? 8 Years Ago by Doogledude123 Iterating through them. Does each iteration trigger a reorder? I don't want to iterate over the same ones multiple times. Re: Should I use a LinkedHashMap for this? 8 Years Ago by JamesCherrill Iterating any Collection will visit each member once. Do you specifically need to iterate them in the order in which they were created? Re: Should I use a LinkedHashMap for this? 8 Years Ago by Doogledude123 Now that I really think about it, No I do not believe so. I'll explain what I want to Accomplish. I recently enabled BitLocker on my Desktop PC and I am having issues with Start Up programs not starting (because they are on another drive which isn't unlocked with the system drive). I am going to create an application which will be stored on the … Re: Should I use a LinkedHashMap for this? 8 Years Ago by JamesCherrill Why not just take a copy of the list at startup and remove each program from the copy when its started? When the copy is empty you are done, and the original list is still there for next time. (Presumably the original list is a disk file, and the copy is the loaded list in the Java program) Re: Should I use a LinkedHashMap for this? 8 Years Ago by Doogledude123 Yeah, that's what I was going to do. I'm just not sure the best class to use. Re: Should I use a LinkedHashMap for this? 8 Years Ago by JamesCherrill It doesn't matter! You just need to process and remove entries until there are none left. Any Collection will do. With, I dunno, maybe a dozen entries there is no issue about space or runtime efficiency. Pick one at random.. how about about ArrayList? Re: Should I use a LinkedHashMap for this? 8 Years Ago by Slavi Just out of curriocity ... what is the startup method used by the ones that don't start by default? You could also just delay them to start after 30 secs or a minute(I've got conky on my unix system to start 20 secs after user log in for example) when the drive is unlocked, cant you? BTW in my case, I have a bash script that is executed upon start… Re: Should I use a LinkedHashMap for this? 8 Years Ago by Doogledude123 Awesome James, thanks as always. Slavi, The thing is about just simply delaying it is that if I don't unlock the drive before that time, then it won't try again. This way, every 5 seconds I can retry starting the program if it didn't start. Re: Should I use a LinkedHashMap for this? 8 Years Ago by Slavi Yeah correct, it has to be done before the time .. Well I guess you could try the way you and James were going for though, just out of curiosity why having start up programs in differnet drives? Re: Should I use a LinkedHashMap for this? 8 Years Ago by Doogledude123 SSD and Storage Drives. My important Programs like my Anti-Virus are put on my SSD whereas the lesser important ones are just put on my Storage Drive. Re: Should I use a LinkedHashMap for this? 8 Years Ago by Slavi If you consider an antivirus program an important one(I don't xD), I would highly advice you to get a tool called PeStudio.
