Final answer:
When the access modifier is omitted from the definition of a member of a class (instance variable or method), the member has default access modifier which grants access within the same package.
Step-by-step explanation:
When the access modifier is omitted from the definition of a member of a class (instance variable or method), the member has default access modifier. The default access modifier grants access within the same package, but not outside of it.
For example, if you have a class called Car and you don't specify any access modifier for its instance variable color, it will have a default access modifier. This means that the color variable can only be accessed by other classes in the same package as Car.
If you want a member to have broader accessibility, you can explicitly specify an access modifier such as public or private.
The member has package-private or default access level. This means that the member is accessible to any other class in the same package, but not to classes in different packages. It is less restrictive than private, but more restrictive than protected or public.
