A variable holds a value, while an object reference variable points to the memory that holds the object.
The short-circuit logical operators && and || operate only on boolean operands. For example, the expression 9&&7 will not compile. Understand the difference between short-circuit logical operators and bitwise operators.
If the first expression of a && operator is false, the second expression is not evaluated, and if the first expression of a || operator is true, the second expression is not evaluated.
Look Out
Be on guard for words that are only slightly different from the
Java keywords, such as synchronize instead of synchronized, implement
instead of implements, and protect instead of protected.
Whether an array stores primitive variables or object references, the array itself is always an object.
It is illegal to include the array size in the array declaration.
Division by zero generates a runtime ArithmeticException only if
the operands are integers. In case of float and double, the result of
division by zero is infinity.
The result of the modulo operator always carries the sign of the first operand (i.e. the one before the operator); you can ignore the sign of the second operand.
You cannot instantiate an enum by using the new operator.
Memorize
Know the Java language keywords.
Know the range of values for all primitive data types.
All primitive data types except boolean and char are signed.
The first character of an identifier must be a letter, a dollar
sign ($), or an underscore (_). Characters other than the first
character in an identifier may be a letter, a dollar sign, an
underscore, or a digit.

The method name and return type are mandatory in a method
declaration. Even though you are not required to specify a modifier in
a method declaration, the default modifier is assigned to the method,
if you don’t declare one.
A static variable belongs to the class and not to a
particular instance of the class, and therefore is initialized when the
class is loaded, and before the class is instantiated.
Because a static method belongs to a class and not to a
particular instance of the class, it cannot access the nonstatic
methods and variables of the class in which it is defined.
An instance of an inner class can only exist in an instance
of the outer class, and has direct access to all the instance variables
and methods of the outer instance.
If you make a super call or a this call, it must be in the
beginning of a constructor. That means you can make either a super call
or a this call, but not both.
Look Out
The variable-length parameters list must appear last in the
parentheses of a method and it consists of a data type, three dots, and
a name, in that order.
A Java class cannot inherit from more than one class, but it can inherit from one class and one or more interfaces.
The class that inherits from an interface must provide
implementation for all the methods that are declared in the interface
if the class is not abstract.
An interface can extend another interface but it cannot implement another interface or a class.
Memorize
If you do not provide any constructor for a class you write, the
compiler provides the default constructor for that class. If you write
at least one constructor for the class, the compiler provides no
constructor.
If you don not make a this or a super call in the beginning of a constructor, the compiler places a super() call there.
You use the keyword extends to write a derived class that
inherits from a parent class, and use the keyword implements to write a
class that inherits from an interface.
The methods in an interface are inherently public and
abstract, and the variables in the interface are inherently public,
final, and static.

Simple Mail Transfer Protocol (SMTP), documented in RFC
821, is Internet’s standard host-to-host mail transport protocol and
traditionally operates over TCP, port 25. In other words, a UNIX user
can type telnet hostname 25 and connect with an SMTP server, if one is
present.
SMTP uses a style of asymmetric request-response protocol popular in
the early 1980s, and still seen occasionally, most often in mail
protocols. The protocol is designed to be equally useful to either a
computer or a human, though not too forgiving of the human. From the
server’s viewpoint, a clear set of commands is provided and
well-documented in the RFC. For the human, all the commands are clearly
terminated by newlines and a HELP command lists all of them. From the
sender’s viewpoint, the command replies always take the form of text
lines, each starting with a three-digit code identifying the result of
the operation, a continuation character to indicate another lines
following, and then arbitrary text information designed to be
informative to a human.

The MailcapCommandMap looks in various places in the user’s system
for mailcap file entries. When requests are made to search for commands
in the MailcapCommandMap, it searches mailcap files in the following
order:
1) Programatically added entries to the MailcapCommandMap instance.
2) The file .mailcap in the user’s home directory.
3) The file /lib/mailcap.
4) The file or resources named META-INF/mailcap.
5) The file or resource named META-INF/mailcap.default (usually found only in the activation.jar file).
