System : It is a java class in the java.lang package.

Out : it is a static field in System class.it holds the
reference of an object of the class printStream.

Println() : it is the method in the
PrintStream class.

so because out is static we can call it using class name
and because of it is returning object we can call methods
present in the object.and one of the method is println.
