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

Please ensure that:

  • Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
  • You include any and all error messages in full - best also formatted as code block
  • You ask clear questions
  • You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

SoTrue
I do Data Structures and Algorithms in Java. I have the intuition every time but I fail to implement them correctly.

Coding things yourself without getting help, from outside is the important

Revision is the most imp thing. I wasted a lot of time. I covered every topic in depth from core Java. But didn’t revise(I’m so stupid) and looking back I don’t remember a word!! I just have the memory of studying it in depth but no context. So revise (pls!!)

Maybe things have changed in the past 20-25 years but how is number 2 a thing? That's the core of any language. Definitely not something I (or my class) did. You'd fail classes almost immediately.
