Packages - Best Practices

It's good practice to import only the specific classes you need. For the wildcard example, we could have imported the classes separately:

If you don't specify a package at the top of your Java file, the class is placed in the default package. This means that any other class in the default package can access it without needing an import statement. However, classes in named packages cannot access classes in the default package. It's good practice to always define a package for your classes to avoid potential naming conflicts and to better organize your code.
