'system' is a class and 'println' is a method in that class, then what is "out"?

Actually, it's a static instance of the class PrintStream.

In Java, the "out" in "System.out.println()" is a class, which was already discussed in a previous comment. This class resides in the "System" package and, to put it simply, represents an IO stream to your "System", which is interpreted as a stream to your monitor.

out is another object of the system object. so its a object within a object then println is a method of the out object.

It's called a "namespace". It doesn't do anything in and of itself, instead it encapsulates different output functions like println(). the "in" namespace would encapsulate writelin().

out refers to output. Not sure which language you are programming in, but out selects the STDOUT stream (prints to console). So system.in would then be the STDIN stream (keyboard input).
