Answer:

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

{

}

musickatia [10]

Answer:

The complete program is as follows:

m_str = input('Input m: ')

mass = float(m_str)

e = mass * 300000000**2

print("e = ",e)

Explanation:

This is an unchanged part of the program

m_str = input('Input m: ')

This converts m_str to float

mass = float(m_str)

This calculates the energy, e

e = mass * 300000000**2

This is an unchanged part of the program

print("e = ",e)

To ____ a public member function of a base class in the derived class, the corresponding function in the derived class must have
Norma-Jean [14]

Answer:

None of the mentioned options

Explanation:

  • If we define a method in a derived class with same declaration type as that of base class then it is said to be overriding a function which behaves differently which will depend on the object which is calling the method.
  • Option a,b and c are not any kind of methods we implement using coding.
  • Option d is done when number or data types of parameters are different than the declaration of the base type.

Given two 2x3 (2 rows, 3 columns) arrays of integer , x1 and x2, both already initialized , two integer variables , i and j, and
Gnesinka [82]
JAVA programming was employed...

What we have so far:
* Two 2x3 (2 rows and 3 columns) arrays. x1[i][j] (first 2x3 array) and x2[i][j] (second 2x3 array) .
* Let i = row and j = coulumn.
* A boolean vaiable, x1rules

Solution:

for(int i=0; i<2; i++)
{
   for(int j=0; j<3; j++)
   {
      x1[i][j] = num.nextInt();
   }
}// End of Array 1, x1.

for(int i=0; i<2; i++)
{
   for(int j=0; j<3; j++)
   {
      x2[i][j] = num.nextInt();
   }
}//End of Array 2, x2
This should check if all the elements in x1 is greater than x2:

x1rules = false;
if(x1[0][0]>x2[0][0] && x1[0][1]>x2[0][1] && x1[0][2]>x2[0][2] && x1[1][0]>x2[1][0] && x1[1][1]>x2[1][1] && x1[1][2]>x2[1][2])
{
   x1rules = true;
   system.out.print(x1rules);
}
else
{
   system.out.print(x1rules);
}//Conditional Statement

Suppose that a t-shirt comes in five sizes: S, M, L, XL, XXL. Each size comes in four colors. How many possible t-shirts are the
guapka [62]

Answer:

120

Explanation:

This question is basically asking how many ways can we arrange 5 sizes of shirts if they come in 4 colors.

5 permutation of 4

To find permutation, we use the formula

P(n, r) = n! / (n - r)!

Where

n is the size of the shirts available, 5

r is the color of each shirt available, 4

P(5, 4) = 5! / (5 - 4)!

P(5, 4) = (5 * 4 * 3 * 2 * 1) / 1!

P(5, 4) = 120 / 1

P(5, 4) = 120

Therefore, the total number of shirts available is 120
