Answer:

The description for the given question is described in the explanation section below.

Explanation:

a...

interface Shape

{

public double getArea();    // creating a function

public double getPerimeter();   // creating a function

}

b and c...

  • I preferred Interface although abstract classes are being used when children's classes associate certain aspect methods and variables and because all classes represent a certain method throughout the specific solution, not instance variables, it would be easier to construct an interface.
  • Almost all of the period interfaces are favored because they have multiple inheritance capabilities.

7.12 LAB: Even/odd values in a list
Korvikt [17]

The odd values in a list can be calculated by knowing the first and last number, whereas even numbers can be divided by two and the remainder is zero (0).

<h3>What are even numbers and odd numbers?</h3>

The even numbers can be found in a list because they are divisible by two and the remainder of this equation is always zero (0).

Conversely, odd numbers are those that cannot be divided exactly into exact entire numbers (e.g., 3, 5, etc).

The odd numbers in a list can be calculated by the equation ON (odd numbers): n/2 × [f + g], where 'f' is the first number and 'g' is the last number.

In conclusion, the odd values in a list can be calculated by knowing the first and last number, whereas even numbers can be divided by two and the remainder is 0.

When creating a presentation in Libre Office Impress, where does the editing of slides take place?
kondor19780726 [428]
The Canterbury Tales, written towards the end of the fourteenth century by Geoffrey Chaucer, is considered an estates satire because it effectively criticizes, even to the point of parody, the main social classes of the time. These classes were referred to as the three estates, the church, the nobility, and the peasantry, which for a long time represented the majority of the population.
