Garbage Collection: If no longer any obejct need to any variable, java automatically reclaimes the memory.U can't force the GC, U have to give the request by using system.gc() and even not guarante that its immediatly to reclaims the memory...........

garbage collection means releasing the memory free from the objects that can no longer be refferenced.No it can't be forced.............. although system.gc() or whatever may request for garbage collection but when exactly it would be started is at the discretion of JVM.

what is the draw back in using friend function in c++

The basic problem is that it blows away your encapsulation. Friend functions see right through "protected" and "private" and can see blinkin' everything.Or, in other words, "your friends get to play with your private parts." :)
