When ever System.out.println("") executing JVM doing like
that System is a class, out is object of PrintStream class,
println() is a method in PrintStream class.

'System' is a class in 'java.lang' package, which is a final
class(can not be inherited) and its constructor is
private(can not be inherited)
'out' is a static member variable of 'System' class which is
of type 'PrintStream'
'println()' is a method of 'PrintStream' class So
'System.out.println()' means calling of method 'println()'of
the static 'PrintStream' type variable 'out' of 'System' class.
And is used to print a String to the system console.
