The name of the file and the name of the class must coincide exactly. For example the Queue class must be in a file named Queue.java. Note that Java is case-sensitive (even though some versions of MS-Windows are not).

The only exception to this rule is that all constructors must be listed first. For example, in a Queue class, the constructor(s) should be first, the pop method should be second, and the push method should be third.

In other words, class/instance variables should be declared at the top of the class (before any methods are declared) and variables that are local to a method should be declared at the top of that method (before any other lines of code). The only exception to this rule is that index variables in loops may be declared locally.

So, the following is discouraged:

             int age = 35;
             

and you should, instead, do the following:

             int age;

             age = 35;
             

Within each category, public variables must be declared first, followed by protected variables, followed by package variables, followed by private variables.

For example, variables of type double should be declared before variables of type int which should, in turn, be declared before variables of type Node.

In addition, each "word" within a class name should start with an uppercase letter. For example, TextMessage and SimpleTrafficMonitor are both appropriate class names.

Further, "words" within a "constant" name must be delimited by an underscore character. For example, EXTREMELY_UNHEALTHY is an appropriate name for a "constant".

Further, each "word" within a variable name should start with an uppercase letter. For example, importantMessage and campusMonitor are both appropriate variable names.

In general, even single-character variable names should be lowercase. However, in some situations, mathematical notation uses uppercase letters. In such situations, uppercase variable names may be used. For example, matrices are often written using uppercase letters. So, an expression like (b = A*x) would be appropriate.

Variable names like aaa are not appropriate. Index variables and counters can, however, have names like i and j.

Do not rely on default visibilities.

Indeed, they must have private visibility unless there is a very good reason for them not to.

This comment must describe the complete class (rather than the methods in the class), must be in javadoc format, and must include: an @author element (containing your full name), an @version element (containing the date or a version number), and the line This work complies with the JMU Honor Code..

This comment must describe the method, must be in javadoc format, and must include an @param element for each formal parameter and an @return element if the method is not void. These comments must be in the order they are listed and must not be empty.

Instead, the operator must appear on a new line.

Except for array initializations, which must be indented 8 spaces. Also, tabs characters must not be used.

Parameters in constructors and setters may.

They may be used with JUnit packages.
