I was wondering if there is any way to know how many objects are present and how many unclaimed by the garbage collector while a program is being run. For instance in a code of 1500 lines there may be numerous objects still alive even though not going to be used.

Which brings me to another question what effect do unclaimed objects have on the efficiency in terms of memory usage.Do unclaimed objects have any effect on the program ?

There's no way (AFAIK) in the standard API to ask the garbage collector how many objects are waiting to be cleaned up.

Ofcourse the garbage collector takes a small amount of processor time, and objects that are not cleaned up take up memory, but you should normally not be concerned with it - the garbage collector contains some very clever algorithms to keep things as efficient as possible.
