Create a generic class, madLabClass, with one type parameter (the generic stuff we learned)

• The class will have 3 backing fields
  • One is an integer for an index
  • The second is an array of the type passed in through the type parameter
  • The third is an integer for insertion index
• A constructor for the class will take in one parameter of int
  • This will initialize the backing field array to be of the size sent in
    • Remember: initialize means making the actual object itself
  • The index backing field will be set to 0
  • The insertion index backing field will be set to 0
• A method called Stuff
  • This will have one parameter
    • Type will be the type parameter
  • When called, it will insert the value provided to the method at the index position stored in the insertion index field
  • Increment the insertion index field
  • The insertion index field stop at the maximum value allowed for the array
    • All future calls to stuff will keep setting the last item of the array to the new value
• A method called Stuff
  • This will have two parameters
    • One is of the type parameter
    • The other is an integer
  • This will insert the value (the type parameter) into the location specified by the integer
    • If the integer value is too large, display a message saying that the value could not be inserted into that position (tell me the value and the position) and tell me how many items the array can actually hold
• A method called DisplayValue
  • print out the current index and the current value of the element in the array being pointed at by the index
    • E.g. The first time this is called and if my array has {"green", "red", "blue"} we may see

index 0 = green

• advance the index by one
• if the index is out of range, loop it back to the beginning
  • if the array has 3 items, but index is 3 (integer = 3), we are now wanting to access the fourth item, which does not exist.
  • If this is the case, how do we get back to the first item?
• Show it working

In the main of the program

• instantiate your class using one data type
• Add some values to your array
• Run DisplayValue numerous times
• Instantiate another variable of the madLabClass using a different datatype
• Add some values
• Run DisplayValue more times than there are array elements (e.g. if my array can hold 21 items, run it 23 times)

Question 2

Add to your madLabClass a generic method called talkToMe

• Will have a type parameter list of 2 types
• Will have 3 method parameters, using a mix of the 2 types (mix it up)
  • E.g. 2 method parameters of type1 and 1 of type2, or ...
• Will print out the value of the 3 objects and the types of the variables
  • Remember to use the toString function (we don't know if they can be printed out unless we explicitly make them strings)
  • The GetType function will return the datatype of the variable
    • myVariable.GetType()
• Will be a static method
• Will not return anything

Invoke and execute a few different variations of talkToMe

Example output could be:

vari (System. String) = Hello Var2 (System . Int32 = 1 var3 (System.String) = bob Press any key to continue
