How to Contribute

Coding Guidelines

• Solution must use Java 8 SE, as this is the version used by the book.

  • Every solution should have a java file containing a public main method for testing it.

  • Naming convention is: ExerciseCC_EE.java where CC is the chapter number and EE is the exercise number.

  • The public Exercise class containing the main method must include a JavaDoc comment on the class with original exercise question.

  • Each solution should be its own self-contained program with minimal dependencies on other files. If you need multiple files please create a package for the exercise.

    • ch_XX/exercise22_07/Exercise22_07.java

    • This allows us to utilize the Exercise Checking Tool Exercise Checking Tool to verify solutions.

• Example exercise solution:

package ch_01;

/**
 * 1.1 (Display three messages) Write a program that displays Welcome to Java,
 * Welcome to Computer Science, and Programming is fun.
 */
public class Exercise01_01 {
    public static void main(String[] args) {
        System.out.println("Welcome to Java");
        System.out.println("Welcome to Computer Science");
        System.out.println("Programming is fun");
    }

}

Pull requests:

• When to use Pull Requests

  • To add new solutions, that do not already exist.
  • To add new documentation and/or comments to existing exercise solutions.

• How to use Pull Requests

  1. Fork the Master branch
  2. Create a feature branch (with a descriptive name) using the fork from step 1.
  3. Make your changes to your new branch (Only commit and push the files you plan to merge).
  4. Make a Pull Request into our intro-to-java-programming Master branch.
