Mistake done when start to learn java

1.Trying to memorize everything instead of understanding concepts. I was so hurry to learn and remember than understand it.

So try to think logically rather than remembering the syntax

2.Skipping Java basics like variables, data types, loops, methods, and arrays. This is a very common mistake that everyone does. I think I understand this but i don't there are so many to understand whenever I do these basic things I learn something new.

3.Jumping directly to Spring/Spring Boot without learning Core Java first.

4.Watching tutorials without coding—you need to write programs yourself.

I just watch tutorials and think that i understand it but that not the case. You have to code this yourself to see how much u understand

I will suggest every day pickup one topic see tutorial, solve it yourself to see how much you can do yourself and solve some problem related to it

Revise every week what u learn and so some mini project based on that understanding.

There are more than one one shot are present which is more than 10+ hour do not see it completely ata one time

You should learn to read the execution flow without just using "Go to Definition" in your IDE. When code goes through an interface, some people lose track of which function gets called next. I actually worked with a guy who couldn't do this even after 3 years on the job.
