How does a serial collector work?
What will be an ideal response?
A garbage object is defined as an object that is no longer be reached from any pointer in running programs under a JVM. A linear garbage collection algorithm simply iterates over every reachable object. Any objects without a reference are then considered garbage. This is also how a serial collector operates. The performance of this approach is proportional to the number of live objects, which is prohibitive for large applications that maintain great amounts of live data.
