Can i know in "System.out.println" which one executes first whether println or out class
In System.out.println , out is not a class it is a field of the System class, check API. The field out is of type PrintStream, println is a method of the PrintStream class, you can check the API for the PrintStream class.It is always good t refer to the API if you have such doubts in the future.
