Why do you not try vectors to create 2d arrays...?

Try this code snipset...

Vector Row = new vector();
// this is main vector for rows
// whenever you want to add an row, just create a new vector and add it with the vector Row.
{
 Vector row1 = new Vector();
}
// if you want to add a column in an i'th row,
// point to that vector object and in that object add the data.

Row(i).add(data); // may not be exact in syntax. check it.

 You can add any count of rows and columns using this.
It is very dynamic.

Try out and let me know about the result.

good day.

You do want to nest array lists. But since the return of a "get(int index)" is an Object, you have to cast it to an ArrayList before you can access the arraylist. Here's how to do it.

     ((ArrayList)a2.get(index)).size();

The compiler (and most IDE's like Eclipse, JBuilder, Forte or NetBeans will recognize this structure for code completion) is smart enough to figure out what you are wanting to do.

Good luck
