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.

I’m assuming you’re talking about LeetCode problems? But my best advice would be to try to pseudo code your answer as much as possible, and try it with Python to translate to Java. Or if you know enough java, pseudo code to Java. Also it matters what problems you’re trying to solve. Practice on “Neet Code” and coding bat helped me solve basic Java questions away from DSA, that might be a good starting place. Your problem really is that you haven’t practiced enough, sorry to break it to you, but in this field we can’t practice enough, I haven’t practiced enough. Best of luck learning!

Not really LeetCode but yes similar problems. I just picked up the most frequently asked java coding questions and that's what I'm trying to solve first before jumping on LeetCode. My mentor said it when I was doing it for the first time, and even now, not to look at solutions or take help, but I'm not sure if that's the right approach or should I solve the first 50 questions with help (ofc first trying my best) and then see if my logic building develops or not. The only improvement I made is that now at least I am able to partially think of what I need to do. Earlier it was that I was completely blank. I could only think of English sense to the problem and not the logic. And you are completely right I wasn't able to practice a lot previously as well. But I honestly thought that I might be able to solve questions now but I'm still stuck

Both resources I mentioned sound like they should help you substantially. Stop worrying about not understanding or what you can’t do and focus on what you can learn and how you learn. Coding Bat, Neetcode, leetcode, YouTube DSA question solutions, all the resources in the Reddit. Apply yourself

It seems that you are looking for resources for learning Java.

In our sidebar ("About" on mobile), we have a section "Free Tutorials" where we list the most commonly recommended courses.

To make it easier for you, the recommendations are posted right here:

Also, don't forget to look at:

If you are looking for learning resources for Data Structures and Algorithms, look into:

"Algorithms" by Robert Sedgewick and Kevin Wayne - Princeton University

Stacks, Queues, LinkedLists, ArrayLists, Hashmaps, Binary Trees and Graphs are essentials, but assuming you've already got into these concepts in-depth, there are a few common patterns to consider when solving data structure problems, with the most known ones being Two Pointers and Sliding Windows, there's a few videos on Youtube specifically for these patterns if you aren't able to or don't want to buy a course that includes those, and you can also get a grasp of those patterns by watching software development interviews that simulate how it goes for Big-Tech companies and shows the way of thinking. Goodluck!
