ArrayList

[Rajat Sarkar]

ArrayList list =new ArrayList(); & ArrayList<Object> list = new ArrayList<Object>();
is both statement works same?is there any difference between them?

You can add objects to both the lists. Only place where it breaks is when you assign any other type safe ArrayList to ArrayList<Object>. Something like this

    
ArrayList<Object> list1 = new ArrayList<Object>(); 
ArrayList<String> list2 = new ArrayList<String>(); 
ArrayList list3 = new ArrayList(); 

list1=list2; // Compilation Error, You cannot assign an ArrayList of 
               //type String to an ArrayList of type Object
list3 = list2; //Works Fine

The difference was.. the compiler will claim you about he doens't know the type of objects will be in the first List.
anyway.. he assigns Object as Type but in the second case at least he know you provided this information.^^
