System is a predefined class in lang package and out is a
static member with in a System class and also out is an
instance of PrintStream which is a static inner class of
System class and finally print() and println() are member
functions of PrintStream class. So we can call those
methods using out and out is called with class name in
which it is declared( bcoz it is static member variable of
system class). So finally we can call println as
System.out.println().
EX:
class System {
static public PrintStream out;
public static class PrintStream {
public string print(String s) {
}
public string println(String s) {
}
public static void main(String[] arg) {
System.out=new PrintStream();
System.out.println("");
}
}
}
