hi all,
i got an array question. i'd like to create a new array and append nodes to it in a loop, like this:

You can add the following line below inside the loop:

allChildren[index] = aNode;

You need to give integer value for index.

Arrays don't keep track of the last used members -- so it doesn't have a concept of append. You can set any member as such...

allChildren[some_index] = anode;

You have two options. You can keep track of the last used location yourself, or you can use one of the collections classes that does do it -- such as ArrayList or Vector.
