Write the definitions of two classes Day and Night. Both classes have no constructors, methods or instance variables. Note: For this exercise, please do not declare your classes using the public visibility modifier.

class Day

{

}  

class Night

{

}

Explanation:

Given

Two classes named: Day and Night

Requirement: Both classes have no constructors, methods or instance variables. should not be declared using the public visibility modifier.

The syntax to define a class in object oriented programming is

modifier class classname {

 // Constructor

 constructor(variablename) { }

 // Methods

 methods() { ... }

 ...

}

Access modifiers (or access specifiers) are keywords in object-oriented languages that set the accessibility of classes, methods, and other members. Examples are private, public, protected, etc.

Going by the syntax above to define class Day

Day

private class Day{

 // Constructor

 constructor(duration)

{

this.duration = duration;

}

 // Methods

CalculateDate() { ... }

}

But the question states that both classes have no constructors, methods or instance variables. should not be declared using the public visibility modifier.

So, class Day will be defined as follows

class Day

{

}

It could also be declared using visibility modifiers other than public modifier.  So, class Day will be defined as follows

private class Day

{

}

and

protected class Day

{

}

Similarly, class Night can be defined as follows

class Night

{

}

private class Night

{

}

and

protected class Night

{

}

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
