NEED IN JAVA ECLIPSE

For this lab, you will create a program that uses method overloading and a switch statement.

Requirements:

The Patapsco River Valley Running Festival needs a program that will allow them to calculate

the cost of the entry fee for each group of entrants. Once the cost is calculated, it is then

displayed to the user.

The program also totals up the total amount of money that will be collected and displays the total

at the very end when the user states that they have no more entries.

You will use the program you wrote in Lab 3 as the starting point for this lab. All of the data

entry for each program is exactly the same. However, the program now displays the cost of the

race entered and the total cost of all of the races.

CODE FROM LAB 3:

/**
*
*/
package volunteers;

/**
*
*
* This program will create a counter which will count the number of Howard County residents attending the event versues the number of
* non- Howard County residents. The program will also tally the number of runners in each of the race lengths. Finally, the program
* will collect the age of the runner.

This enhanced program will need to do the following calculations:

Race Event- 5K

Howard County Res Cost- $25

Non-Howard County Res Cost- $40

Race Event- 10K

Howard County Res Cost- $35

Non-Howard County Res Cost- $50

Race Event- Half Marathon

Howard County Res Cost- $65

Non-Howard County Res Cost- $85

Race Event- Full Marathon

Howard County Res Cost- $85

Non-Howard County Res Cost- $115

Race Event- Fun Run

Howard County Res Cost- $20

Non-Howard County Res Cost- $25

Non-Howard County residents who are 18 years of age or younger or 60 years of age or older get

a $5 discount on their entry fee. There are no discounts for county residents.

You should use a switch statement to implement the table, and you should not use the reserved

word "return" within the switch statement.

NOTE: There should be only ONE named method (an overloaded method is acceptable) to

determine and return the cost of the event for Howard County residents and non-Howard County

residents. Use the method parameters to distinguish between cases.

You should declare constant values for all of the costs listed in the table.

This code should all be contained within one class file.

OUTPUT SHOULD LOOK LIKE THIS:

Would you like to add a runner? Enter 'yes' or 'no'.
