Programming & Computer Science Answers

A member class has id, name and payment rate. In member class make 1 abstract method: calculateSalary(): that calculates Salary of each member in arraylist. Write another class ContractMember that extends Member

a. Provide a data member contractStart and contractEnd (LocalDateTime) 

b. Provide a static constant TAXRATE and initialize it to 0.07

c. Provide getters, setters and appropriate constructors

d. Override the method calculateSalary which calculates the salary by finding the number of days between the start and end of the contract and callculating the salary for these days @ of the rate defined earlier. The method then deducts tax from this amount @ the TAXRATE and returns the net payable amount as salary.

e. Override the toString to match the output 

You are required to write builds a record book for Projects being conducted at a department. A Project has an id, description, a list of members and start and end dates. In Project class make 2 abstract methods: getTeamSize(): that finds and returns the size of the team working on this project c and calculateCost(): that finds and returns the total cost of project. Provide the class MixedTeamProject which extends Project

a. This class represents a project that can have mixed types of members

b. Override the getTeamSize() appropriately so that it counts all members but makes sure that only active adhoc members are counted if there are any

c. Provide the implementation of calculateCost method so that the cost is calculated as under

i. Salaries are added for adhoc members

ii. Salaries of contract members are added but 11% tax is added for each contract member salary

iii. Salary of all hourly member is added and a flat amount of 1000 is added to cover additional cost.

Write a program to store following numbers in an array

3 10 -15 20 12 8 -3 7

then display all the numbers without showing negative numbers(i.e. -15 and -3)

Write a program to create an array in order to store 15 numbers then display only even numbers in one line and also display how many even numbers found.

1. The change in the heat capacity of a substance due to temperature is given in the table below. Calculate the heat required to raise the temperature of 1-mole of the substance from 300 K to 1000 K using (a) Trapezoidal rule and (b) Simpson’s rule.

(Hint: )

T (K) / C_p (Cal/mol.K)

300 19.65

400 26.74

500 32.80

600 37.74

700 41.75

800 45.6

900 47.83

1000 50.16

1. Integrate the function below between the limits 0 and 0.8 by (a) Trapezoidal rule and (b) Simpson’s rule.
