Error on OCP 1Z0-815 BOOK Deshmukh, Hanumant Page 237

[javiut]

I dont know if i already made this but i dont see it on the errata.

In page 237

10.5.3 Accesing static members from the same class.

I see

Code: Select all

System.out.println(InstanceCounter.printCount()+" "+InstanceCounter.count);

But this is a compilation error because the printCount() method is void and cannot be inside a System.out.println

Best regards.

You are right. It should be :
InstanceCounter.printCount()+" "+System.out.println(InstanceCounter.count);
Added to errata.
thank you for your feedback!

I think this would not work either.

InstanceCounter.printCount()+" "+System.out.println(InstanceCounter.count);

InstanceCounter.printCount() is void and you cannot append a value void.

This might work.

InstanceCounter.printCount();/*JUST LET THIS LINE PRINT ITSELF*/
System.out.println(InstanceCounter.count);

[admin]

Right! What was I thinking!!
Updated.
