hi friends,
I have a samll doubt..
Does garbage collection guarantee that a program will not run out of memory or not ?

No, it doesn't guarantee that, as you can always write a program that uses more memory than is available; for example, the one line

int[][] matrix = new int[1000000][1000000];

will exhaust the memory of any 32-bit JVM.

What garbage collection does do is free you from the need to deliberately delete memory you're no longer using, as you have to do in languages like C and C++.
