the annotation

@interface Dirt{
 public Color color();
}

I dont think that this line with 'Color' compiles and so "line 6 " ie option  E should be one of the incorrect options   given  on the answer page 662

Welcome to the Ranch

Thank you for using the code button but you didn't quite get it right. Please see this link about it. The two halves of the tags go around the code, but don't worry. I corrected it for you. Doesn't it look better (). Please don't double‑space code.
Have you tried compiling that annotation? What happened? Please supply more details for those of us who don't have the book.

It should probably be in the OCJP Forum, rather than Java in General, since the OP was alleging an incorrect answer in cert exam prep materials provided by authors who frequent the Ranch.

The full code of the example is:

import java.lang.annotation.Documented;
enum Color {Grey, Brown}
@Documented public @interface Dirt {
    boolean wet();
    String type() = "unknown";
    public Color color();
    private static final int slippery = 5;
}

The answer choices are:
A. Line 2
B. Line 3
C. Line 4
D. Line 5
E. Line 6
F. Line 7
G. All of the lines compile.

I agree with the printed book's explanation that only D and F represent lines that would not compile.

If Color is an enum, there is no reason that line won't compile. If Color is a normal class then you'll indeed get a compiler error. If you're trying this out in an IDE and get an error on this line, are you perhaps using java.awt.Color unintentionally?
