Answer Posted / surinder mehra
Garbage Collection for an object occurs in following cases:
1) All references of that object explicitly set to null
e.g. object = null
2) Object is created inside a block and reference goes out
scope once control exit that block.
3) Parent object set to null, if an object holds reference
of another object and when you set container object's
reference null, child or contained object automatically
becomes eligible for garbage collection.
Garbage Collectors are implicitly invoked by JVMs when
needed(when there is no enough space for coming objects to
store). or jvm can call garbage collectors whenever it
finds that object is not being used for long time. It is
marked as garbage and later on collected
