Grading Rubric

Coding standards Comments:

- Include comments before each statement of logic

- Include comments for every closing brace - }

Class Names:

- Use meaningful class names (e.g. ConvertLength, not ClassA)

- Capitalize the first letter of each word

Constants:

- Use capital letters

- Separate words with ‘_’

- No data type characters preceding constant name

Variables:

- Declare one variable per line

- Comment each variable to explain what information is stored

- Use meaningful variable names (e.g. nCount, not n)

- Initialize variables when declared

- Capitalize the first letter of each word

- The name of each variable should start with a letter to indicate the data type

Control Structures:

- Statements enclosed within a compound statement are indented one level from the enclosing braces

- Each new level of logic is indented (usually a tab, or 4-5 spaces) from the preceding level

- Braces enclose the contents of all logic constructs, and the closing brace is followed by a comment

- Each else statement is on a separate line and vertically aligned with the corresponding

if

Methods:

- Method definitions should be declared after the main method or after class constructors

- Value-returning methods should have one and only one return statement, and it should be the last statement of the method before the closing curly brace }

Method names:

- Should help describe what the method does

- Should not start with the data type letters (like variables)

- The first “word” in the method should be all lower case letters. Additional words should start with a capital letter 2

Logic

- Program works correctly for both scenarios

- Output formatted according to sample output

- Appropriate and correct definition and use of the Student class

- default constructor used with option #1

- overloaded constructor used with option #2

- Student object used with all other options

- Menu logic and processing contained in main method

- Appropriate and accurate use of { } to create compound statements for if/else and loop structures

- Calculations stored in variables – NOT calculated directly in System.out.println

statements

- Output prints values from variables, not hard-coded values (e.g. “0”)

- Only include import statements required for constructs used in source code

- Appropriate data types used for each variable and constant

- Appropriate use of constants
