list.remove(item);……………?????????

this is error prone in case list is accessed by an iterator simultaneously. Code is not suitable for multi-threaded environment.

You’d do it about the same way. First you’d need to convert the array to an ArrayList. Then you’d need to get the index (indices) of the objects. You can do this using the indexOf method on ArrayList. However, make sure you override the equals method in the TetrixBox class. See this post http://code.hammerpig.com/find-an-object-in-an-arraylist-with-java.html. Then remove the objects based on the indices.

Hopefully I’m understanding your question correctly. Please let me know if this helped.

and what if i want to remove indexes from a non-primitive type? (yes i know String isn’t techniqually a primitive data type)

Say i have an array of type “TetrisBox”, and suddenly 10 of these indexes or elements, i don’t want anymore, i want to get rid of them (i’m sure you can see the reason for this). how would i do that? because i obviously can’t pass them as a string?

You should be able to do it with a multidimensional array. You’d just treat each element as an array. Have you tried and it didn’t work? If so, can you post a (simple) code snippet?

Nice clean code, but what if I wanted to remove a row from a multi-dimenensional String array
