hi guys,

i need some help.

i want to create a class that has a constructor to create an arraylist. then i want to create another MAIN class that will create new arraylist objects. how can i do this?
i tried something but i'm getting compile errors.

for instance i wanted to create a class like this



my main class



but the problem here is, i want the contructor to create an array list that will take an argument of how the Arraylist<String> is to be named.

i know this is simple, but i forgot how to do this somehow. please help me out

thanks.

For people to be able to help you, you need to show what you tried, as well as copy/pasting the exact complete error message into your post, and indicating clearly which line caused it.

i just want to create new objects of Names class and maybe passing in arguments that will be names of the ArrayList.

i hope it's clear now what i want to achieve

thanks.

I'm not sure, but it's definitely not clear what problem you're having.

Okay, but what do you mean a "name for an ArrrayList"? Objects don't have names, so are you defining some class that will contain an ArrayList field and a name field, so that you can associate that name with that list?



Or perhaps you're thinking of passing in a variable that refers to an ArrayList? Note that a variable is not an object's name. Objects don't have names.

 
I agree. Here's the link: http://aspose.com/file-tools
