Question

In JAVA

Algorithm Workbench 1. Write the first line of the definition for a Poodle class. The class should extend the Dog class. 2. Look at the following code, which is the first line of a class definition: public class Tiger extends Felis In what order will the class constructors execute? 3. Write the statement that calls a superclass constructor and passes the arguments x, y, and z. 4. A superclass has the following method: public void setValue(int v) value = v; Write a statement that may appear in a subclass that calls this method, passing 10 as an argument. 5. Write the declaration for class B. The class's members should be as follows: • m, an integer. This variable should not be accessible to code outside the class or to any class that extends class B. . n, an integer. This variable should be accessible only to classes that extend class B or are in the same package as class B. • setM, getM, setN, and gets. These are the mutator and accessor methods for the member variables m and n. These methods should be accessible to code outside the class. • calc. This is a public abstract method. Next, write the declaration for class D, which extends class B. The class's members should be as follows: • 9, a double. This variable should not be accessible to code outside the class. • r, a double. This variable should be accessible to any class that extends class D or is in the same package. • setQ, getQ, setR, and getR. These are the mutator and accessor methods for the member variables q and r. These methods should be accessible to code outside the class. • calc, a public method that overrides the superclass's abstract calc method. This method should return the value of times r. 6. A superclass has the following abstract method: public abstract int getValue(); Write an example of a getValue method that can appear in a subclass. 7. Write the first line of the definition for a Stereo class. The class should extend the Sound System class, and it should implement the CDplayable, TunerPlayable, and Cassette Playable interfaces. 8. Write an interface named Nameable that specifies the following methods: public void setName(String n) public String getName()

If you have any problem in understanding the answer feel free to comment

Answer 1.

public class Poodle extends Dog{

//write the characteristics and behavior of the class

}

Answer 2.

In the main method when the constructor of the Tiger class is called it will pass the call to its superclass Feils. So first Felis constructor is called and then Tiger constructor is called.

Answer 3.

//demo class

public class B extends A{

public B(int x, int y, int z){ //considering there are type as int

super(x, y, z);//passing the values to superclass constructor

}

}

Answer 4.

We can use this superclass method using super keyword: super.setValue(10);
