Which is efficient Arraylist or Hashmap??
Hi,
Actually, my project flow is
html,css,js<--->ajax<-->jsp<--->jdbc(.java)<--->mysql.
In that jdbc i am returning the records from the database and fill into the resultset. From the resultset i put all records in arraylist and passed to jsp then i am displaying data in the screen.
I need a suggestion which one is efficient to use. Whether i can use arraylist, hashmap or treetable?????

Re: Which is efficient Arraylist or Hashmap??
Before determining which is most efficient, I'm not sure the choices you've listed are equally appropriate for what you're trying to do. Further, if what you're doing is working, why change? Are you experiencing an issue that requires you to seek a more efficient approach? If so, what's the issue you're trying to solve?
Re: Which is efficient Arraylist or Hashmap??
In your case its better if you make a POJO( Plain old java object), while retrieving the data in the result set instantiate the pojo and pass that pojo object to jsp.
Re: Which is efficient Arraylist or Hashmap??
I feel ArrayList would be a better way to implement the stuff you are trying.
Thanks and regards,
Sambit Swain
