This is the most powerful design pattern Java practical tutorial on the whole network. The website is: Java Design Pattern Practical Column Introduction-Self-study Wizard
The Power of This Design Patterns Column
- Use Java actual combat to introduce commonly used design patterns, so that you can really master the design patterns.
- Use the actual scene of the project to carry out design pattern combat, and combine it with SpringBoot , so that you will apply it in the project after you learn it , and you will carry out the project structure ! !
- Introduce the typical application of common design patterns in projects, let you harvest offers during interviews , and beat the interviewer !
Comparison of this column with other sources
Characteristics of other materials
- The description of the meaning of design patterns is only in life, not in projects.
- There is no actual project example, it is all code describing life, and this kind of example is hardly reminiscent of a project.
- The code is written in bare Java, without SpringBoot, which is very cumbersome.
- Each mode uses only one way of writing, and there is no comparison of various ways of writing.
The above ultimately leads to: the design pattern cannot be applied to the project after learning, and the interviewer can't answer the questions. Learning is tantamount to learning for nothing !
Features of this set
- Use life examples to help you understand the thinking of the model, and use actual project cases to let you understand how to apply it.
- The code examples are all actual project scenarios , allowing you to learn how to use them in actual projects.
- The code has the cumbersome writing method of bare Java, and the concise writing method combined with SpringBoot .
- Each mode has various writing styles ranging from cumbersome to concise, and there are comparisons of various writing styles .
After learning this set of practical design patterns, you will be able to directly apply them to projects , design complex projects , and directly beat interviewers .
Why learn design patterns?
- Design patterns are skills that must be mastered by intermediate and senior Java developers (including development team leaders and architects) .
- If you don't master the design pattern, you can't design and structure the core functions of the project, and you can only be a junior Java developer.
- Design patterns can improve development efficiency , code reusability , scalability , and maintainability
- Design patterns are a must-ask in Java backend interviews
How to learn design patterns?
effective learning methods
- Master the commonly used design patterns (know the actual combat), understand the uncommon design patterns (just know the name).
- First understand the general concept, and then use the actual scene of the project to actually write the code.
Follow this column to learn, you can quickly and thoroughly grasp the design pattern and its application.
ineffective learning method
- Attempt to master all design patterns
- There is no need to master the design patterns that are not commonly used, just understand them.
- View PDF or book
- I have read many design pattern books and PDFs, including: "Head First Design Patterns", "23 Design Patterns", "Design Patterns Java Edition", "Design Patterns: The Foundation of Reusable Object-Oriented Software".
- After reading it, I found that the content in the book cannot be applied to the actual development of Java at all, and I couldn't tell it when I asked it during the interview! Learning is equal to learning in vain !
- Look at other people's design pattern articles on the Internet
- The actual articles on design patterns on the Internet are all written codes with examples in life.
- After reading it, I found that their articles could not be applied to the actual development of Java at all , and they were not combined with SpringBoot, so I couldn’t tell when I asked them in the interview! Learning is equal to learning in vain !
