Under Primitive Data Types section, line 5:

Changed the following sentence: In Java, all variables have guaranteed default values, though the compiler may warn you in places where you rely, accidentally, or not, on these default values. to The same is true in Java; the Java compiler does not let you write code that uses uninitialized local variables. Note, however,that the fields of Java objects do not have garbage values; they are automatically initialized to standard default values.

Remove the fourth paragraph (the one that starts "There is an

important point..." and replace it with: There is an important point to make about subclass access to f(CWprotectedfR members. A subclass inherits the f(CWprotectedfR members of its superclass, but it can only use those members through instances of itself, not directly in instances of the superclass. Suppose, for example, that f(CWAfR is a f(CWpublicfR class that defines a f(CWprotectedfR field f(CWffR and a f(CWprotectedfR method f(CWm()fR. Now, suppose that f(CWBfR is a subclass of f(CWAfR defined in a different package. f(CWBfR inherits the field f(CWffR and the method f(CWm()fR from f(CWAfR, and the methods of f(CWBfR can refer to the inherited field and method with expressions like f(CWffR, f(CWm()fR, f(CWthis.ffR, and f(CWthis.m()fR. However, if a method in f(CWBfR creates an instance f(CWafR of class f(CWAfR, it fIcannotfR use the field f(CWffR and the method f(CWm()fR of that object. That is, the class f(CWBfR cannot use expressions like f(CWa.ffR and f(CWa.m()fR. ("f(CW" and "fR" indicate that the intervening text should appear in constant width font.)

Colophon: The animal featured on the cover of Java in a Nutshell is a Javan tiger. It is the smallest of the eight subspecies of tiger, and has the longest cheek whiskers, forming a short mane across the neck. The encroachment of the growing human population, along with increases in poaching, led to the near-extinction of the Javan tiger. The Indonesian government has become involved in trying to preserve the tiger. It is to be hoped that the remaining subspecies of tiger will be helped by increasing awareness and stricter protections.
