How can I learn most of libraries in java?

Question

Hello guys.
I wanna learn most of libraries in java but many resources just teach some libraries and I can't do anything as I want in java.
Now please suggest a way to learn most of libraries in java which can be helpful for me.🙏🏻

Answer 1

Java language API is huge. There is no way to learn all, or even most of it, for any single developer. However we do have to use many parts in code, even those we are unfamiliar with.

So what is the right strategy here?
Try to get the big picture, by understanding what tools are available to you, and where to find information about them.
One of the best places to start, would be the JDK documentation.
https://docs.oracle.com/en/java/javase/17/
You can find here the description of the core API, and also tutorials.

Enrolling in a course, that shows the most important aspects and features, can also be very helpful. Some of these courses are even available for free, like on YouTube.

If you want to research a specific topic, my favourite Java source is Baeldung blog. They do have lots of Introductory articles about language features.

Also if you work with a certain framework such as Spring, they have very detailed documentation on their own website too.
