They must be used with private methods. They are accessible from anywhere inside or outside of a class. They can never be used in a class. They can be accessed only by methods inside the class they are associated with.Write a constructor for the IceCreamCup class. The constructor takes the name, and a List of Flavor s (name it fList) as parameters. It initializes the instance variables with the parameters. Use shallow copy for initializing the list of Flavor s. (Throw an IllegalArgumentException if the name is null, or the Flavor list is null or empty.) Note that successful instantiation should increase nCups by 1.
- public class Father { public String name; public int age; // customer name Father(){ name=”Hassan”; age=50;} public void display(){ System.out.println(“Name:”+name); System.out.println(“Age:”+age); } } 1. Based on Figure 3, create a class named Child that inherits the Father class. Declare an instance name location (String) for class Child. 2. Define a constructor in class Child and give an appropriate initial values for the instance (name, age, location). 3. Define a method display () in class Child, execute the display ( ) method in superclass using the keyword super. Method display ( ) in class Child should print the information of name, age and location 4. Create other class named Main for the main method and create 2 objects for the 2 classes (Father and Child). Then execute the display ( ) method for Father and Child.
