Answer to Question #292703 in Java | JSP | JSF for Yash

Question

Class Name : Worker

Name : To store the name of the worker

Basic : To store the basic pay in decimals

Worker (…) : Parametrized constructor to assign values to the instance variables

void display() : Display the workers details

Class Name : Wages

hrs : Stores the hours worked

rate : Stores rate per hour

wage : Stores the overall wage of the worker

Wages (…) : Parametrized constructor to assign values to the instance variables of both the classes

double overtime() : Calculates and returns the overtime amount as (hours*rate)

void display() : Calculates the wage using the formula wage = overtime amount + Basic pay and displays it along with the other details

Specify the class Worker giving details of the constructor () and void display ( ). Using the concept of inheritance, specify the class Wages giving details of constructor ( ), double overtime( ) and void display(). The main ( ) function must be written to perform the task.

Answer 1

	private int hrs;
	// rate : Stores rate per hour
