♥ In Architecture Documentation: When you write architectural documentation, using patterns will reduce the amount of documentation you need to write and gives the reader a clearer picture of the design. As a result, other developers who have to read your code will thank you for allowing them to quickly understand your implementation. Also, choose class and method names that follow any patterns. ♦ In Code Comments and Naming Conventions: When you’re writing code, clearly identify the patterns you’re using in the comments. Moreover, Design Patterns will also be useful in your Professional Career in multiple places. If you know Design Patterns, it will lead to better code structure, better communication, and, best of all, it will save you a lot of time that you can spend on cooler things. How are Java Design Patterns useful in your Professional Career? What are the advantages/benefits of using Design Patterns?ġ) Design Patterns help in finding the solution of a complex problem.Ģ) Using design patterns, we can make our code loosely-coupled.ģ) Furthermore, it will have the option of reusable codes, which reduce the total development cost of the application.Ĥ) Additionally, future developers feel the code more user-friendly.ĥ) It has all the standard approaches to find out solutions to the common problem of a software.Ħ) We can use the same pattern repeatedly in multiple projects.ħ) Moreover, It helps in refactoring our code in a better way. Particularly, they are useful to us while we think about a solution to a problem during project development. However, they help to to design a better software. Please note that Java Design Patterns are not closely related to Java Application Design. If you are planning to apply for a job as an experienced developer, keep in mind that your interview will not be completed without questions on Design Patterns. In contrast, if you are weak in design patterns, you will face a lot of problems while developing, even sometimes you may need to modify your code from the beginning, that can result in pain & frustration. If you are strong in design patterns, you will complete your development earlier than the expected time and number of bugs will also be very negligible. Even you will be able to suggest a better solution to a problem instead of the existing one. Also, you will never feel low while developing a project. If you have strong concepts in Java Design Patterns, your confidence level will also be high because design patterns itself provide you solutions for many common use cases. Moreover, Design Patterns will help us in fixing performance and memory related issues. Why do we need to learn Design Patterns?ĭesign Patterns help us to solve a problem during project development. Since then, these are called GoF Design Patterns. These four authors are altogether known as the Gang of Four ( GoF). It was 21 October 1994, when four authors Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides, with a foreword by Grady Booch, published a book titled as Design Patterns – Elements of Reusable Object-Oriented Software which launched the concept of Design Pattern in Software design. When we talk about these types of solutions to recurring problems in Java language, they become ‘Design Patterns in Java’ or ‘Java Design Patterns’. Some people in the industry also call it a template as it solves the problems while developing the application. In a software industry, Design Pattern is a description or guideline to solve a problem that occurs repeatedly while developing a software Application.
