Lab 01

Sorting Various Words by Various Properties

Objective:

Write a program that analyzes a collection of words and sorts them in ascending order by the number of vowels, consonants, and the length of the word.

Lab Solution

Requirements:

• Functionality. (80pts)
• No Syntax, Major Run-Time, or Major Logic Errors. (80pts*)
• *Code that cannot be compiled due to syntax errors is nonfunctional code and will receive no points for this entire section.
• *Code that cannot be executed or tested due to major run-time or logic errors is nonfunctional code and will receive no points for this entire section.
• Do not user built-in array sorters. (80pts*)
• * Using any built-in or automatic sorting methods (such as Arrays.sort()) will result in 0 points for this entire section.
• Set up the Project. (20pts)
• First download the driver file and the text file and include it in your project.
• Create a class and name it, exactly, WordHelper.
• Do not modify the provided driver or text file.
• All must apply for full credit.
• Write method sortByVowels. (20pts)
• This static method returns a sorted String array, takes in an array of Strings via a parameter, and sorts them from smallest to largest by the number of vowels.
• In addition, this method must create a copy of the String array parameter, sort the copied array, and return the sorted copied array.
• A character’s case does not matter, and you may assume that all words only contain alphabet characters and no digits or special symbols.
• Write method sortByConsonants. (20pts)
• This static method returns a sorted String array, takes in an array of Strings via a parameter, and sorts them from smallest to largest by the number of consonants.
• In addition, this method must create a copy of the String array parameter, sort the copied array, and return the sorted copied array.
• A character’s case does not matter, and you may assume that all words only contain alphabet characters and no digits or special symbols.
• Write method sortByLength. (20pts)
• This static method returns a sorted String array, takes in an array of Strings via a parameter, and sorts them from smallest to largest by the number of letters.
• In addition, this method must create a copy of the String array parameter, sort the copied array, and return the sorted copied array.
• A character’s case does not matter, and you may assume that all words only contain alphabet characters and no digits or special symbols.
• Coding Style. (10pts)
• Code functionality organized within multiple methods other than the main method, and methods organized within multiple classes where appropriate. (5pts)
• Readable Code (5pts)
• Meaningful identifiers for data and methods.
• Proper indentation that clearly identifies statements within the body of a class, a method, a branching statement, a loop statement, etc.
• All the above must apply for full credit.
• Comments. (10pts)
• Your name in the file. (5pts)
• At least 5 meaningful comments in addition to your name. These must describe the function of the code it is near. (5pts)

Additional Notes:

• Arrays in Java are considered class/object types which means they are referenced by their memory addresses. Just like other class/object types, passing an Array via a parameter DOES NOT create a clone. Each method mentions to first create a copy of the provided array, sort it, and then return the sorted copied array, and this is a very important detail to get the same example dialog as below. If this step is left out, the solution will only appear to sort only by the length as the initial array was first sorted by vowels, then the SAME array was then sorted by consonants, then the SAME array was sorted by length, and finally the SAME array is printed three times. We instead need to make copies so that we can retain the original while also having 3 additional version sorted in a variety of ways.

Example Dialog:

*The following Example Dialog demonstrates the interactions between a user and the user interface provided by the driver file along with the other provided files. *
