Assignment Details
Many modern languages, including Java, are provided with a set of classes, methods, and objects built in. An example of this is the Scanner class, which facilitates user input and is part of a base-level package of utilities known as java.util. You can read more about java.util in the below linked article from the official Java documentation at Oracle:
Package java.util from docs.oracle.com
As you can see from the article, java.util contains 29 interfaces, 77 classes, 21 exception handlers, and a variety of other tools and capabilities. And this is only a tiny part of what’s available.
Learning every utility, class, and object in Java would take a great deal of time and offers little gain in return since you can easily look them up as needed. This is why, unlike other areas of Information Technology, memorization plays a smaller role in the educational journey of a software developer. There is benefit in learning what resources are available, because nearly every project will call on your ability to quickly adapt to new tools and methods.
Your main post for this discussion has two alternatives: You can write about another built-in class in Java, or you can write about a built-in class or classes in another language.
If you decide on the Java option, select a built-in Java class (like Scanner but a different one). Explain what it is used for, provide an example of how it might be used in an application, and show a simple example of its use in Java code. You may use course learning materials such as the zyBook, or the JavaDocs online documentation, or any other resource you wish.
If you decide on the non-Java option, choose a programming language other than Java and consider the available resources for a new software developer who wishes to use that language. In your post, explain the language that you chose and provide an example of a built-in class (like Scanner in Java). Explain what the class is used for, provide an example of how it might be used in an application, and show a simple example of its use in code (1 or 2 lines in the selected language; this does not have to be original code). You may use any resource for this that you wish.
Note: The code sample is intended to be extremely simple, need not be original, and should not have to be executable on its own, or a complete program. For example, if you were discussing the Scanner class you might show: “Scanner input = new Scanner(System.in);” This would be sufficient to show how the class is used.
When replying to other students, share additional resources for the student’s selected language, or compare the resources they found with the ones you found in your own investigation. Is there another Web site that explores that language or class that you ran across? Are there videos on YouTube that show how to use that class? Perhaps you found had an interesting example that you could share.
