Answer to Question #281526 in Java | JSP | JSF for asmf

Question

You are required to write builds a record book for Projects being conducted at a department. A Project has an id, description, array list of members and start and end dates. In project class provide two abstracts methods: getTeamSize(): that finds and returns the size of the team working on this project c and calculateCost(): that finds cost of the project. Provide a class HourlyTeamProject that extends Project, Add an instance variable hourCost (double) that represents the utility bills cost charged per hour worked on this project by each team member. Provide a method getTotalHours() that returns the total number of hours worked by each member on this project. Override the calculateProjectCost method which calculates the total cost by following relation

     Total cost = total salary of all members + hoursCost * total hours on this project
