What is a design pattern?

The important reason for creating a program by applying design patterns is
This is to make it easier to respond to various additional requirements .
That is, to make it easy to modify the code.
Through my previous experiences, the experiences of others, etc.
In this situation, if the purpose of the modification is this, it is better to do it like this.
A design pattern is something that is systematically organized.
So when we apply design patterns to programming,
It will make programming a little more comfortable.

The 'Design Patterns with JAVA (Gof)' course explains some of the Gof Design Patterns using Java.

The usefulness of design patterns

Making a 2nd multiplication table


💁🏻‍♂️If I need to print from 1 to 999, what would be a good method?
🙋🏻‍♀️[Method 1] requires a very long hardcoding, whereas [Method 2] only requires changing the condition inside the for loop to i<1000!
💁🏻‍♂️If I need to print 3 columns, what would be a good method?
🙋🏻‍♀️[Method 1] requires you to change all 2s in the horizontal line to 3, whereas [Method 2] only requires you to change int n = 3; and you're done!
This example is not a design pattern, but if you apply design patterns to your project, it will look like this example.
It makes it easier to respond to various additional requirements.

    The lecture content was a bit disappointing. I thought it would be a practical code that could be used right away in practice, but it was a bit disappointing. Also, while the beginning was written step by step, from the middle to the latter part, it was a bit disappointing that it just pasted the source code and gave a rough explanation. It would have been better to understand if it had been written step by step, but since it was too fast to paste the code and explain it, I missed a lot of parts and had to go back and look at them. However, for those who lack the basics or do not have a basic understanding of design patterns, I think they will get the feeling that this pattern is implemented this way. Anyway, it is an overall disappointing lecture with poor quality.

        I bought a book to study design patterns and watched YouTube lectures, but this was more helpful for my understanding. I like the part where each pattern is explained step by step. However, not all the pattern explanations were like that. I took off one star because I had high expectations after reading the lecture introduction. I agree with Freelife's lecture evaluation.

          I tried to study design patterns by reading books and looking for lectures... I finally found a lecture that I like.. Overall, it was well organized, and most of all, I liked the examples. It's not easy to provide sufficient understanding with short example sources, but I could feel that a lot of effort was put into it. Thank you for the great lecture..I think it would be helpful for other developers to listen to it once.^^

            I had a vague feeling about design patterns, but through this lecture, I was able to easily understand frequently used design patterns. I recommend it to those who are curious about Java-based design patterns~
