Hi, so currently in my Java course, I'm learning about abstract classes. I noticed how a method in an abstract class can use an access modifier, however, interfaces don't use them.
In addition to this, I noticed that IntelliJ didn't give me an error stating that adding an access modifier was redundant or useless. So I wanted to know if there is a point in adding access modifiers to abstract methods.
Thanks so much for anyone who can help me out with this!

    Abstract methods can be anything (visibility wise) other than private. Nothing stopping you specifying a protected abstract method for example.

    Method definitions in interfaces though are always public (ignoring Java 8+ with static / default methods), so the public visibility modifier is always redundant.
