  • JVM : Java Virtual Machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are compiled by bytecode. You can read more on this from freecodecamps’ article .
  • Class : A class is a blueprint used to create and object. Think of this like having a sketch/ guide of how to make a Cup. The sketch can be given to someone else and used by them to make their own cup and customize it if need be.
  • Object : An instance of a class. From the prior example , think of this like you have had your sketch / guide on how to make a cup, now you decide to make multiple cups or a cup with a unique shape, size, color or whatever attribute that has been given in the cup sketch/ guide.
  • Hashcode : Numeric representation of an objects’ contents so as to provide an alternate mechanism to identify it, by default the hashcode() method returns an integer that represents the internal memory address of the object .

Thank you very much ..
