Yes, it is a human issue and not a compiler issue. 1) For me, having the classes defined within the method enhances readability.

The notion of a 'marker' interface is somewhat retired in Java now that we Fri, 03 Jul 2009 21:18:07 GMT David Bock http://tech.groups.yahoo.com/group/novajug/message/13408 http://tech.groups.yahoo.com/group/novajug/message/13408 Keith, Regarding garbage collection and memory allocation, the speaker you referred to earlier was Brian Goetz. If you summarize the thread into a concise Fri, 03 Jul 2009 18:27:04 GMT Madhu Siddalingaiah http://tech.groups.yahoo.com/group/novajug/message/13407 http://tech.groups.yahoo.com/group/novajug/message/13407 ... I'm with you there. I continue to be amazed at how good modern collectors are, but you can abuse the collector if you try hard enough. We had a case years Fri, 03 Jul 2009 18:19:24 GMT Madhu Siddalingaiah http://tech.groups.yahoo.com/group/novajug/message/13406 http://tech.groups.yahoo.com/group/novajug/message/13406 ... This is probably not a simple number as it depends on object graph complexity. You might get a ballpark value, but it's probably easier to measure it for Fri, 03 Jul 2009 16:25:12 GMT Keith R. Bennett http://tech.groups.yahoo.com/group/novajug/message/13405 http://tech.groups.yahoo.com/group/novajug/message/13405 Madhu - I agree with everything you said, except for a couple of points: 1) As implied by David, the statement that "allocating more memory is costlier than Fri, 03 Jul 2009 16:05:55 GMT David A. Sisk http://tech.groups.yahoo.com/group/novajug/message/13404 http://tech.groups.yahoo.com/group/novajug/message/13404   Just one small point,   Mark and sweep is only for the tenured objects and is designed to decrease the amount of stop the world GC's   If these objects Fri, 03 Jul 2009 15:43:44 GMT Madhu Siddalingaiah http://tech.groups.yahoo.com/group/novajug/message/13403 http://tech.groups.yahoo.com/group/novajug/message/13403 ... Allocation is only one half of the memory management problem. Sure, heap allocation can be as cheap as stack allocation, but the same can't be said for Fri, 03 Jul 2009 15:35:43 GMT jawabean http://tech.groups.yahoo.com/group/novajug/message/13402 http://tech.groups.yahoo.com/group/novajug/message/13402 ... yes, sometimes i feel like "fighting the system", but there are benefits of using Java as opposed to C++. i won't list them here, as those here who Fri, 03 Jul 2009 13:16:37 GMT David Sisk http://tech.groups.yahoo.com/group/novajug/message/13401 http://tech.groups.yahoo.com/group/novajug/message/13401 As discussed earlier, the JVM is tuned for short lived objects, in the case of allocating inside a loop the only concern is generating the objects faster than Fri, 03 Jul 2009 04:59:42 GMT Keith R. Bennett http://tech.groups.yahoo.com/group/novajug/message/13400 http://tech.groups.yahoo.com/group/novajug/message/13400 ... Brian - What you say about allocating an object outside of a loop being more efficient is common sense and is almost certainly true. I say almost because
