1. Write the first line of the definition for a Stereo class. The class should extend the

SoundSystem class, and it should implement the CDplayable, TunerPlayable, and

CassettePlayable interfaces.

2. Write an interface named Nameable that specifies the following methods:

public void setName(String n)

public String getName()

3. Look at the following interface:

public interface Computable

{

 double compute(double x);

}

 Write a statement that uses a lambda expression to create an object that implements the Computable interface. The object’s name should be half. The half object’s compute method should return the value of the x parameter divided by 2.
