no you cannot - you need to have System.out.println("hello");

this is class System
http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/System.html

it is part of java.lang. which will be imported by default

as this is name of the class it should be upper case and Java is case sensistive

out is a static varibale of class System so you just append it after dot to the class name without any instance System.out

And out belongs to class PrintStream and then you use method println()
of that class to print

if you just leave it
println(..)
it will look fro the method println(..) of the same class which you are creating and if you did not define such method it will complain that there is no such m,ethod in your class

If you

import static java.lang.System.out;

Open in new window


you can do

out.println

Open in new window


but i wouldn't. Just write your own method called println if you want to call it
