Answer:
Syntax is essentially the punctuation and grammar rules for a computer language.
Explanation:
Certain characters and words have special meanings and must appear in a particular order for the computer code to make any sense. A simple example from line 3 in Figure 2.2 is the piece of HTML code <head>.
The answer is NO.

d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
Answer:
Explanation:
Based on the information provided within the question it can be said that the text that supports this is that in the book it states that this disorder is due to an obvious "addiction" to the sheer thrill of hacking, born of having found ways around the supposed ingenuity of "invulnerable" cyber security defences.
