Design patterns are proven solutions to common software design problems. They can help you build software that is easier to manage and adapt to change. This article will guide you through using the Design Patterns in Java repository provided by Refactoring.Guru, alongside troubleshooting tips to overcome potential issues.

Requirements

The examples in this repository were written in Java 8 and have also been tested in Java 9. For the best experience, we recommend using the free Community Edition of IntelliJ IDEA.

Setting Up the Project

To get started, follow these steps:

• Download or clone the repository to your computer.
• Open IntelliJ IDEA and import the root directory of the repository into a new project.
• Through the start dialog, select the “Import Project” option and follow the prompts.
• Or via the main menu, navigate to File > New > Project from Existing Sources…

Once the project is imported, you can run the examples by right-clicking on Demo files in each example and selecting the Run command.

Understanding the Code: An Analogy

Let’s visualize the structure of the code in this repository using the analogy of a city plan. Imagine your codebase as a bustling city, where:

• Packages are like different neighborhoods (residential, commercial, industrial), categorizing related classes, akin to how specific environments cater to particular functions in life.
• Classes are houses within those neighborhoods, each serving as unique entities (like families) that contribute to the area’s diversity.
• Methods are the activities performed by those families that define their functionality, ensuring that the environment is lively and engaging.

Thus, just like a well-planned city needs its neighborhoods, houses, and activities to function effectively, a well-structured codebase with appropriate packages, classes, and methods enhances maintainability. Each component is distinct but interrelated, facilitating a smoother run of applications.

Troubleshooting

If you encounter issues while running the examples, here are some common troubleshooting tips:

• Ensure JDK 8 or 9 is properly installed and configured in IntelliJ IDEA.
• Check if the project structure is correctly set up. Sometimes missed imports could lead to problems.
• Make sure that your files follow the Google Java Style Guide for consistency.
• If a specific class isn’t running, verify that you didn’t miss any dependencies while setting up.
