copying contents of an ArrayList to another ArrayList

[ankit1801]

i need to copy contents of an arraylist arr1 in another new arraylist arr2. how to copy the contents?

[camickr]

Have you read the ArrayList API? What constructors or methods do you think might be helpful?

[nap_patague]

you can try to loop the contents of array to and then copy the contents to the array 2

(hint: an ArrayList is a Collection)

Why is that better than using the constructors and methods provided by ArrayList?

I remember you telling me that when I was too new to know it </nostalgia>

[nap_patague]

it is just my suggestion. or he can may be use to just initiate it on another arraylist

newArrayList = oldArrayList

And I remember camickr telling me that text components have a read() method that is better the ugly, slow, memory exhausting line by line code I had!

it is just my suggestion.

And it's a perfectly workable suggestion. It's just that I can't see why anyone would make it, or follow it given what camickr had previously posted.

newArrayList = oldArrayList

The OP wanted to copy the contents of the list.
