related to best practice

[vasu chowdary]

Hi,

I have small doubt about ArrayList. As a part of the webservice response object i get the ArrayList where i can find exactly 3(not more ,not less and not null) objects in that list.Based on the 1st object value i have to populate another object and based on 2nd object i have to populate another object.So my question is instead of writing below logic

  for(int i=0;i<arrayList.size();i++){
     if(i==1){
        //do somthing
     }else if(i ==2 ){
        //do somthing
     }else if(i==3){
        //do somthing

     }
}

can i directly access the object based on the index like below

   arrayList.get(1);
   arrayList.get(2);
   arrayList.get(3);

Why not?

Just remember that it's zero-indexed, so use arrayList.get(0), etc.

You mean:

   arrayList.get(0);
   arrayList.get(1);
   arrayList.get(2);

yes i mean
arrayList.get(0);
arrayList.get(1);
arrayList.get(2);

i heared that this not the best practice.is it correct?

Think why it is ArrayList and not an array?
