If you go over to the java docs you will see that package private word is used to signify default or no modifier.

It means that a class or any member without any modifier will be visible only within its own package. You can take reference from java docs. A Java package organizes Java classes into namespaces, providing a unique namespace for each type it contains.

The methods or data members declared as private are accessible only within the class in which they are declared. Any other class of same package will not be able to access these members. Packages are used for: Preventing naming conflicts.

So to your point, the private access, as known in Java , was not there originally. But when you have more than a few classes in a package , not having private as we know it now would lead to a nightmare of name collision (for example, java.until.concurrent has close to classes), which is probably why they introduced it.
