Java #

The corporate programming language.

It’s got a large ecosystem of supporting projects and is somewhat easier to use than C++.

The general idea is that the JVM has been optimized so much over the years that Java programs aren’t slow-by-default anymore.

I know a decent amount of Java, but not enough. I still don’t know what classpaths and packages are.

Plan #

• Setting up a development environment.
• Learn a bit about the internals of the JVM.
• A playbook for common tasks.
• Refactoring code according to SOLID principles.

Is this too unorganized? There’s a more structured way to learn Java : dev.java that you could follow.

Do something with this? #

So many courses and tutorials. What do I do with this knowledge? 🤔 No idea, honestly.

Fun facts #

There’s a bunch of FAQs on the Collections API. About their design.
