Chapter 18, Problem 7PC
Program Plan Intro
Generic class to find out largest, smallest, total and average of elements in an ArrayList
Program plan:
- Import the required package.
- Create the class “MyList” with a type parameter “T” that is constrained to an upper bound Number using the keyword extends,
- Create “ArrayList” as a field of class “MyList” with type parameter “T”.
- Define the constructor.
- Define the public method “add()” to accept the parameter of type “T”,
- Store the value in “ArrayList” using the reference variable “list”.
- Define the method “largest()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and compare each value using if statement to find the largest value in the “ArrayList”.
- Return the largest value using the keyword “return”.
- Define the method “smallest()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and compare each value using if statement to find the smallest value in the “ArrayList”.
- Return the smallest value using the keyword “return”.
- Define the method “Total()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and calculate the total value of elements in the “ArrayList”.
- Return the total value using the keyword “return”.
- Define the method “Avg()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and calculate the total value of elements in the “ArrayList”.
- Calculate and return the average value using the keyword “return”.
- Create the class “Main”,
- Define the method “main()”,
- Create the object of a class “MyList” as a type of “Integer”.
- Call the “add()” method to fill the values in the “ArrayList”.
- Call the method “largest()” to print the largest value of “ArrayList”.
- Call the method “smallest()” to print the smallest value of “ArrayList”.
- Call the method “Total()” to print the total value of elements in the “ArrayList”.
- Call the method “Avg()” to print the average value of elements in the “ArrayList”.

This is a cell that should alternate between being alive and dead with each generation. Add one or more of your AlternatingCells to your ConwayWorld. You can see how to add a cell in line 15 - 20 of Main.java. Give your AlternatingCell a unique display character when it is alive so that you can see it in your conway world. 2.

The team has already developed a class named NavigatorApp for storing and displaying the graph representing the road network. This class has a void displayShortestPath() function which takes the source and destination vertices of the trip and displays the shortest route between them. Using the strategy pattern, draw a class diagram of the system which will allow for the NavigatorApp to display the shortest driving, walking, or cycling route when the displayShortestPath() function is called. You can assume that another developer is in charge of making sure the appropriate strategy is correctly set and for calling the displayShortestPath() function Starter code /* Modify NavigatorApp (if necessary) */ class NavigatorApp { private: Graph map; public: void displayMap(Window * window); void displayShortestPath(Vertex source, Vertex destination, Window * window); /* write pseudo code for this function…arrow_forwardStockList Class • This class will contain the methods necessary to display various information about the stock data. • This class shall be a subclass of ArrayList. • This class shall not contain any data fields.
