java – ArrayList> to String [] []

It looks like a JTable construct, like string []]... But I like to use smarter containers until I have to use something else I have been using ArrayList < ArrayList < string > >. Now I need to satisfy JTable with string []

I found a simple way to convert ArrayList < string > Use toarray() to string [], but cannot find a simple converter for multidimensional arrays

I want to start from ArrayList < ArrayList < string > > in the string [] [] with the minimum number of lines

I've been searching the library and can't seem to find this converter, and I hope someone can suggest a good solution

Thank you in advance

You may want to know how to implement your own table model:

You can create a class that extends abstracttablemodel and delegate it to list or any other suitable data structure
