The method NSArray.objectAtIndex(int) returns the type Object. If you know
it's an NSColor, then cast it to an NSColor:
NSColor color = (NSColor) someNSArray.objectAtIndex( i );

Also note that the method-name is objectAtIndex, not ObjectAtIndex. Case
is important.

These are such basic questions you should probably review the basics of the
Java language, or go through a tutorial, such as:
<http://java.sun.com/docs/books/tutorial/>


I also strongly recommend looking at Apple's sample code:
<http://developer.apple.com/samplecode/Sample_Code/Cocoa.htm>
<http://developer.apple.com/samplecode/Sample_Code/Java.htm>

Or just start with the Developer Technical Resources page and go exploring:
<http://developer.apple.com/technical/>

You may also find the Cocoa-dev mailing-list useful:
<http://www.lists.apple.com/mailman/listinfo/cocoa-dev>

Or any of Apple's other mailing-lists:
