System is a class.
out is a public static class variable of the System class.
NOTE: "out" Must be declared public. Otherwise, we cannot
access it as "System.out"
out is of type PrintStream
println is an overloaded method of PrintStream class.
(That's why println method accepts strings, boolean values
or char values)

Here is a good article on that.
