Answer:
Explanation:
1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).
2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.
3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.
4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
Answer:
The solution code is written in Python:
- COST_PER_500MI = 1.1
-
- weight = float(input("Enter weight of package: "))
- total_cost = weight * COST_PER_500MI
- print("The shipping charges is $" + str(round(total_cost,2)))
Explanation:
Based on the information given in the question, we presume the cost per 500 miles is $1.10 per pound ($2.20 / 2 pound).
Create a variable COST_PER_500MI to hold the value of cost per 500 miles (Line 1). Next, prompt user input the weight and assign it to variable weight (Line 3). Calculate the shipping charge and display it using print function (Line 4-5).
In programming they know it as a String which is a sequence of characters that are composed of literal constants or some kind of variables. A sting is any finite sequence of characters. every single string has its own lenght and this is one of the most important characteristics of them. Strings are essential to communicate information from the program to the user.
