What is true about methods in a Java interface?

  1. They can have method bodies if marked static

  2. They are automatically public

  3. They must be abstract

  4. They can be private

The correct answer is: They are automatically public

Interface methods are automatically public, meaning they can be used and accessed by any other class. Option A is incorrect because static methods do not require an object to be called and interfaces cannot have objects. Option C is incorrect because all interface methods are abstract, meaning they do not have a method body. Option D is incorrect because all interface methods are public and therefore cannot be private.
