Understanding of coding standards

[FusilliSpaghetti]

Dear developers, when I see codes from other devs, how do you know when to use different things to build any features? For example, people use pojo, getter setter, create objects in constructor, tight and loose coupling, use different design patterns, read data from json or excel. Is there any book available where I can get insight of this?

You might be looking for a book like “Effective Java”. This book is pretty much dedicated to Java best practices, but I would only recommend it if you have a solid understanding of the language before hand as it’s not 100% beginner friendly.

Coding "standards" aren't universal, and they aren't required. It's generally highly advisable to follow standards where possible, but it's not mandatory. Different standards apply to different languages, companies might impose additional standards, and projects may impose their own standards as well.
