In this video, Doug Winnie explains how to create a custom class. He also reviews what a class package is, and how to create a constructor and class members in Java.
- [Host] While there are pre-built classes…all throughout Java, you can create your own…by defining the blueprint of a class…and then instantiate it in your program.…To create a class you need to create a new java file.…To do this, expand the project folder,…and then open the source folder or SRC.…In there is a folder called com dot company.…This is called the package.…When you create a class it exists in a package.…You can think of packages like a group of folders.…There's a top group called com…and then a second called company.…
You can define these to be whatever you want.…The com dot company package is created by default…when you create a new project in IntelliJ.…On that folder right click and select new,…then select Java Class.…Then you'll see the create new class window appear.…You need to enter the name of the class.…Let's create a class for a cat,…so enter cat with a capital letter.…Classes usually start with a capital letter.…Then click okay.…
When you create the new class you'll see an empty class file…
