After many searches I keep coming up with mixed answers.

What are the integral types in Java?
byte,short,int,char

What are the numeric types in Java?
byte,short,int,long,char,float,double

Why is long left out of the integral type or did I read bad info?

Well, if you're reading older material, the long may not have been invented yet. Of course, you'd have to go a long way back to that time.

The integral types, that is, the ones that can be treated as whole numbers are byte, short, int, long and char.

The numeric types that can have decimals are the double and the float.

So, that pretty much covers it. long is definitely in there!

Thanks Cameron I knew it made since to be in there but different places omitted it.

BTW I've really enjoyed your SCJA cert guide, my test is tomorrow afternoon just doing some last minute cramming!
 
It is sorta covered in the JavaRanch Style Guide.
