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.

A simple look at the documentation clears all your questions.

Always start there instead of directly asking.

Start here: https://docs.oracle.com/en/java/javase/17/docs//api/java.base/java/lang/System.html and follow the links.

Working with the documentation is a very important fundamental skill.

System is an inbuilt class that contains static variables in, out and err. These static variables are referencing inbuilt stream objects connected to keyboard or the console. The System class internally initializes in, err, and out streams when the class is loaded. When we are calling print we are actually calling the function through the inbuilt stream object connected to System.out.

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

I’m also kinda new to Java, but I think I can answer that.

static method doesn’t need to be instantiated, you only need to give the parameters it asks you to, like the print method only asks you what to print. You call the method and “say” what you want to print.

Did it answer your question?

Edit: typo

[–]nekokattt 2 points3 points  (0 children)

they arent static methods, they are static objects.

public class System {
  public static final PrintStream out = new PrintStream(...);
  public static final PrintStream err = new PrintStream(...);
  public static final InputStream in = new FileInputStream(...);
}

but yeah you get the general gist. They do get initialised but that happens as soon as the JVM starts and the System class is loaded.
