Consider the following two classes: Author and Editor. class Author } public String Name; public String skypeID; } public String getskypeID(){ return skypeID; } class Editor public void clear EditingDoubts(Author author){ setUpCall(author.skypeID); } void set UpCall(String skypeID){ } A software engineer commented that the code is tightly coupled and suggests refa the code. Rewrite the code to produce a loosely coupled code.

true of false: a) The first step in any programming task is to start coding. b) The only places we would ever want to put a comment in our code are above a method and above a class.

Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java Programming
Consider the following class definition: class circle { public: void print() const; void setRadius(double); void setCenter(double, double); void getCenter(double&, double&); double getRadius(); double area(); circle(); circle(double, double, double); double, double); private: double xCoordinate; double yCoordinate; double radius; } class cylinder: public circle { public: void print() const; void setHeight(double); double getHeight(); double volume(); double area(); cylinder(); cylinder(double, double, private: double height; } Suppose that you have the declaration: cylinder newCylinder; Write the definitions of the member functions of the classes circle and cylinder. Identify the member functions of the class cylinder that overrides the member functions of the class circle
Below is the definition for a class called "Fruit": public class Fruit { } private String name; private boolean hasPit; // a pit is a large, hard seed in the center of a fruit public Fruit (String newName, boolean hasPit) { name = newName; this.hasPit = hasPit; } public void printFruitDetails() { if (hasPit) { System.out.println("The } } else { } System.out.println("The + name + + name + has a pit. Don't break your teeth biting into it!"); doesn't have a pit. It's easy to slice up!"); Create a short main method which does the following: 1. Creates a Fruit object with the parameters "Avocado" for name and true for hasPit. 2. Creates a second Fruit object with the parameters "Pear" for name and false for hasPit. 3. Calls the printFruit Details() method on the first fruit object. 4. Calls the printFruitDetails() method on the second fruit object.
