Create a class Count with:
i) a public value field storing a numeric value.
ii) the Add method accepting one parameter and adding the passed value to the value held in the value field.
iii) subtract the analogous operation
In Main, create several objects of the Count class and perform various operations.
b) Add a constructor with one parameter to the Count class - which initializes the value field to the number passed in the parameter.
c) Change the visibility of the field to private and add a function that prints the state of the object (value field)
Create a Sumator class with:
i) a public Numbers field that is an array of numbers
ii) a Suma method that returns the sum of the numbers in the Numbers field
iii) a SumaPodziel2 method that returns the sum of the numbers in the array that are divisible by 2
b) Change the visibility of the Numbers field to private and add a constructor.
c) Add a method: int IleElementów () that returns the number of elements in the array
d) Add a method that prints all the elements of the array
e) Add a method that accepts two parameters: lowIndex and highIndex, which will print the elements with indexes >= lowIndex and <= highIndex. The method should work correctly when lowIndex or highIndex are outside the range of the array (skip these elements).
Define a class that describes the date. Consider choosing an internal representation of dates. Define methods that allow you to read the current date and move it forward and backward by one week. Make sure to select appropriate access modifiers to the components.
Define a class Number that stores the digits of a decimal number in an array. Define operations for printing a number, assigning it a value (in the form of a constructor parameter that is a string) and multiplying it by an int. If during multiplication it turns out that the array is too small, the multiplying procedure should copy its contents to a larger one. Finally, define the factorial method, which will calculate the factorial of the int number given as a parameter.
