Solution

The correct statements on differences of abstract classes and interfaces are:

  1. You can implement multiple inheritance in Java.
  2. You can extend only one abstract class.
  3. Interface is better suited for Type declaration and abstract class is more suited for code reuse and evolution perspective.
  4. You can create a non-abstract method in abstract class.

The statement "you can create a non-abstract method in an interface" is not correct because, until Java 7, interfaces could only have abstract methods. However, since Java 8, interfaces can have default and static methods, which are non-abstract.
