Answer:

The code to this question can be given as:

Code:

public interface Test  //define interface  

{

   public abstract Duration getDuration(); //define method

getDuration.  

   public abstract Result check(int a);

//define method

check .

   public abstract double getScore();

//define method getScore.  

}

Explanation:

In the above code, we define an interface that is "Test" inside an interface, we define three methods that can be defined as:

  • First, we define a method that is "getDuration" that method returns  Duration as an object.
  • Second, we define a method that is "check" this method accepts an integer parameter that is a and return Result.
  • The third method is "getScore" this method will return a double value.
