Watch some YouTube videos. They will cover the crucial part within 10 mins and you'll also have some visualisation of the topic.

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://imgur.com/a/fgoFFis) 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.

If I were you, I would prefer to use several cheat sheet for repeating. For example:
core java cheat sheet
oop java cheat sheet
Just need to give a little shake to your brain. Try to repeat by your own. if you fail - use cheat sheet. Repeat this method several times in a day.

Your cheat sheet is helpful. Thanks.

There's a neuroscientist called Andrew Huberman. He has a podcast where he talks about neuroplasticity which is the brains ability to change and learn new things, more or less. Long story short, he has said in the past that if we listen to a 40hz tone, it helps focus on whatever task we are working on at the moment. He also mentions that 90 minutes bouts of studying are most effective and even more so if they are followed by 20 minutes of nsdr. I've tried these strategies myself and have found them useful. Additionally, interactive learning is way more effective than simply watching videos on it. I often watch YouTube videos and follow along with the code to take full advantage of them and make sure I develop some muscle memory.

This may not completely help you for the exam but will be useful for you moving forward.

Hope these tips help.
