You can use ArrayList also .. as ArrayList is not synchronized by default, u can synchronize it forcibly using the method :
Collections.synchronizedList(List list) of the Collections utility class .. this creates a synchronized list from the ArrayList and returns the reference to that .. As Vector is old concept , u should avoid it .. ----- Original Message ----- From: "Amit Ghaste" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, January 03, 2003 12:12 AM Subject: Re: Use of Vector > Vikramjit, > > The reason that Vector is Synchronized is the main reason why I would use it > in a web application... > > I dont want adhoc volatile values to be present.. > > Snehal, > > Could u explain what do u mean by Master Value... do u mean for ex.. of > populating drop down lists, a list that is common across users and sessions. > like an Application level data... > > if so then yes i would use a Synchronized Collection object, Vector works > inplictly as a Synchronized Object, but if u want to use another class then > I would recomend using the Synchroinzation technique in the Collections > class so as to maintain data itegrity. > > Amit. > > -----Original Message----- > From: A mailing list about Java Server Pages specification and reference > [mailto:[EMAIL PROTECTED]]On Behalf Of Vikramjit Singh > Sent: Wednesday, January 01, 2003 10:31 PM > To: [EMAIL PROTECTED] > Subject: Re: Use of Vector > > > > -----Original Message----- > > From: Snehal Pandya [mailto:[EMAIL PROTECTED]] > > Sent: Thursday, January 02, 2003 11:57 AM > > To: [EMAIL PROTECTED] > > Subject: Use of Vector > > > > > > Hi All, > > I have a Application and For that I want to put all Master > > value in the > > Vector . > > Whether this is good programming or it is benifishery. > > My application is for intranet only. > > Please help me how to use it and how to retrive the > > information from the > > Vector. > > vector is not useful for web applications, just coz of the basic reason that > it is synchronized. > You could use other Collection classes or check the List interface. > > My 2 cents: > > For inserting the values use LinkedList (since LinkedList is faster for > insert operations). > LinkedList provides sequential access, additions and deletions, at a cost of > slower random access. > For retrieving or reading the values use ArrayList (ArrayList is faster for > read operations). > > For instance, if your program is to frequently provide random access to the > data of the list, (for example, "show me item three, twelve, two, and > twenty-five") the ArrayList class offers quick access to individual elements > of the list. > > When working with ArrayList and LinkedList, there are two ways of creating > the objects: > > List cityList = new ArrayList(); > LinkedList peopleList = new LinkedList(); > > The above creation ensures that, line 1 that we are creating an ArrayList > but we are gonna use it as a List.
