Java ArrayLists?
If(((ArrayList)list3. Get(row1)). Get(col).
Equals(((ArrayList)connections. Get(row2)). Get(col))){ should read if(((ArrayList)list3.
Get(row1)). Get(col). Equals(( ((ArrayList)connections).
Get(row2)). Get(col))){ You are casting connections. Get(row2) instead of casting connections first and then doing a get on the arraylist EDIT -- You should definitely refactor the code to use Java 1.5 functionality aka generics.
If that's not an option, you should refactor the code to be more readable -- for example : your method is called "connections" and then your variable is called "connections.

You should also use generics instead of casting. That way you will get an error at compile-time if you do this and your code will be type-safe. Generics just specify the type you are using to the compiler so it can check the types at compile-time.
Example: ArrayList> list = new ArrayList>(); list. Add(new ArrayList()); list. Get(0).
Add(0); list. Get(0). Add(1); list.
Get(0). Add(2); More about generics here. Hope this helps.
