pro programmer's opinion needed

[jasonwyz98]

Hello

i'm implementing a substitute teacher's class for a school project, and each sub has a list of preferred schools, subjects, etc that they want to teach. My question is that generally is it a good idea to implement a linked list inside the sub class to contain the list. I've decided not to use array since the list may grow in the future. Any opinions are well come

thanks

welcome to the wonderful world of java, arraylist, not only implements a marker interface (makes it fast especially in version 1.4 and later), also supports growable arrays.

Bear in mind ArrayList is not thread safe, so if you will have multiple or concurrent threads accessing your ArrayList, then you should use Vector, which is synchronized.

that's true. but if you need fast iteration and you aren't doing a lot of insertion/deletion, arrayList is preferred. On
the other hand, if you need to perform FAST insertion/deletion, linkedList with elements doubly-linked to one another is preferred.
