"Normally, non-zero float values are represented as: sign*mantissa*2^exponent where sign is +1 or -1, mantissa is a positive integer less than 2**24 and exponent is an integer in the inclusive range -149 to 104." changed to "Normally, non-zero float values are represented as: sign*mantissa*2^exponent-23 where sign is +1 or -1, mantissa is a positive integer less than 2^24 and exponent is an integer in the inclusive range -126 to 127." (the ^ indicates superscript. In other words, "exponent-23" appears in superscript.)

the railroad diagram should not indicate that the word "super" is a

term, since "super", by itself, is not a valid expression.

There is an error in the railroad diagram for method call

expression. The problem can be fixed by simplifying the diagram: |--- FieldExpression ---- ( --- ArgumentList --- ) ---|

section 5.4.6.3, para. 2, lines 3-4: delete this sentence

"It is also an error to declare a method with the same name as a variable declared in the same class or any of its superclasses."

There is an example program "class foo" which reads: class foo { static int i = 4; static { i += 2; j = 5 * i; // forward reference to j } static int j = 7; // deklaration of j static double d; static frame f = new Frame(); // frame should be Frame static { d = Math.tan(Math.PI / j); } } In the following two paragraphs this example is explained to be correct, especially the forward reference to the variable j, made in the static initializer preceeding the variable declaration. When you compile this, with both JDK 1.1.6 and JDK 1.2, both versions of the compiler says: Can't make forward reference to j in class foo. j = 5 * i; ^ 1 error The specifications for Java said this should be okay, and I believe it used to work with an earlier release, possibly the 1.1 beta. But the specifications were changed just before 1.1 was released. Please disregard this section on forward references. It will be removed from future editions.

the railroad diagram for switch statement is incorrect: the problem

is that the contents of a switch block must begin with a switch label and the railroad diagram does not reflect that requirement. Here's an ASCII version of the corrected diagram: | +---- switch ------ ( --- identifier --- ) ------------------(1) | +---------------------------<-----------------------------+ | | |

Under "public void checkwrite(string file)", "throws securityException",

you write "If the caller does not have permission to 'read from' the named file ...", but the actual description & method name contradict this.

Added the following to the last para.

"Whenever possible, our books use RepKover (tm), a durable and flexible lay-flat binding. If the page count exceeds RepKover's limit, perfect binding is used."
