JAVA INTERVIEW QUESTION: When does an Object becomes eligible for Garbage collection in Java?

· java

An object becomes eligible for garbage collection when there is no live reference for that object or it can not be reached by any live thread. Cyclic reference doesn’t count as live reference and if two objects are pointing to each other and there is no live reference for any of them, than both are eligible for GC. Also Garbage collection thread is a daemon thread which will run by JVM based upon GC algorithm and when runs it collects all objects which are eligible for GC.
