Can someone make a list with the most used and important things in Java?

Question

I would like to know the most used methods, constructors and etc. I plan on focusing on them for a bit until I can freely use them so I want to make sure I am studying the correct stuff.

Answer 1

Well from my very limited experience and class taken in university, almost everything covered in the Java course here are things you'll see a lot. In other words, you should just go ahead and study the topics covered in the course. After that I would look into sorting and searching algorithms then data structures. Also take a look at design patterns and really look into object orientated programming since it's the main foundation of Java
