The interviewer prefaced the technical portion, saying that he knows I may not have answers to all the questions since I am still in school and learning. He just wanted me to reason through and try my best.

I honestly did not have very well thought out answers to the technical interview, but was invited to a second interview on their campus.

In computer science, garbage collection (GC) is a form of automatic memory management. The garbage collector, or just collector, attempts to reclaim garbage, or memory occupied by objects that are no longer in use by the program. Garbage collection was invented by John McCarthy around 1959 to solve problems in Lisp.

In Java, Garbage collector is a program which runs on JVM and removes the Objects which are not used. JVM by default calls gc or you can also explicitly invoke by System.gc(); or Runtime.gc(); commands.
