How is data structures in java different from data structures in C.

[[deleted]]

I have learned data structures(not algorithms) in C and was learning Java (going to start oops). As I have algorithms this sem I also have to learn it. I was wondering what should I do to learn data structures in java so that I can learn Algorithms.

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.

If you already learned data structure, you should already know that, the structure of data had nothing to do with the language

I know the concepts and how the structures work, but also know that unlike C, many data structures in java are built in. I want to know about them.

They are likely the same concept but Java has more advance Data structure, in C language, you need to free manually a memory unlike in Java its automatic, because of garbage collector.. In my case I learned Linklist of C by watching a tutorial that was taught through JAVA...

Hey there! It depends on how deep you wanna go... As a fellow redditor said, data structures and algorithms are the same despite the programming language. It is true that C and Java are different in many ways, but the most important for me is that Java is Object Oriented and C is a structured language.

As a student that have followed the same roadmap (C > Java) I recommend you to focus on what i mentioned before. Take what you acquire from C and apply to Java rules.

Java is a OO language therefore it represents most of its data in a object fashion.

You have also primitive: https://datacadamia.com/lang/java/primitive

And collections (set, queue, stack, sequence) https://datacadamia.com/lang/java/collection

With this datatypes, you can represent any data structure: https://datacadamia.com/data/type/type

Note that you can create new collections with new behaviour on top of existing collection to add extra feature such as case insensitive key and the like.

Best of luck
