Word Frequency Counter

This project offers a Java-based solution for computing the occurrence of words in a text file and determining the word that is used the most often. The project follows clean coding standards, resulting in a solution that is readily comprehensible, manageable, and testable.

Getting Started

Before you start this project, you must have Java installed on your computer. If you don't already have Java, you can download it from the official website.

Project Structure

The project is structured into two main classes:

1. WordCounter: This class is responsible for processing a line of text and updating the word frequency map.
2. Application: This class is responsible for reading a file, processing each line to count word frequencies, and displaying the word frequencies.

How to Run

Compile and run the Application class. The application reads a file located at counting_words/resources/philosophy_of_programing.txt and prints the word frequencies and the most frequent word.

You can run the application from your terminal with the following command:

javac Application.java
java Application

Alternatively, you may use any Java-compatible IDE like IntelliJ by Jetbrains or code editor, such as VSCode.

Output

The output of the application will be a list of words along with their frequencies, sorted alphabetically. The last line of the output will display the most frequently used word in the text file.

Error Handling

The application is designed to handle IOException. If an IOException is thrown during the processing of the file, the application will print a stack trace to help diagnose the problem.

Useful Vocabulary I learned

• Class: A class in Java is a blueprint or template that defines the properties and behaviors of objects— an object in simple terms can be anything, an entity. In this case a WordCounter and an application (computer program) to run (show or display) this WordCounter.

• Map: In the context of java, a map is a data structure that holds information in key-value pairs. It functions similarly to a dictionary in that you may search up a word (the key) and get its meaning or frequency (the value). The map is used in this instance to keep track of how many times each word occurs in a line of text. As a result, anytime a new word is encountered, the map is updated to include it in the count.

• IOException: This is an exception class that represents an input/output (IO) error, such as a failure in reading or writing data.

• Stack Trace: A stack trace is a list of method calls that shows the sequence of execution leading up to an exception or error, like an evidence log.
