I need the code below edit to meet the requirements below:

NOTE: Most of the steps are finished just need to be edited to meet requirements.

NOTE: I marked in the code where the major error is occurring. The error is incompatible types Char cannot be converted into String.

Test 1 (10 pts):

Within the EventManager class:

? Define variables to hold an amount type and an amount value.

? Using the already defined File and Scanner variables from the template,

add code to instantiate a File object and a Scanner object that can be used to read the file whose

name was input by the user.

? Read data from the first line of the file only.

? After reading the line, display a message containing the data from the line read, with the amount

formatted to 2 decimal places, as follows:

Line read: T 111.11

? Close the file.

Test 2 (15 pts):

Within the EventManager class:

? Add loop around the code that reads the data from the file and displays what was read, so that it

reads and displays all lines in the data file (should work no matter how many lines are in the file).

? After all data has been read and displayed, use the constant to display a message including the

filename, as follows:

Done reading file event1.txt

Test 3 (10 pts):

Within the Event class:

? Add a addAmount() method that:

o Has 2 parameters: an amount type letter and an amount value

o Increments the total for the amount type specified by the first parameter by the amount

specified in the second parameter

Test 4 (15 pts):

Within the Event class:

? Add a displayTotals() method that will:

o Display one blank line

o Display the data fields, as follows (with decimals aligned and final digit in column 30):

Within the EventManager class:

? Above the file reading loop,

create an Event object.

? Within the loop, as each line of data is read,

use the Event object to call the addAmount() method,

with the data read from the file line as the arguments.

? After reading all data in the file,

add code to use the Event object to call the displayTotals() method.

Total ticket sales: 2000.00

Total donations: 500.00

Total expenses: 133.33

Test 5 (10 pts):

Within the Event class:

? Add a calcEventProfit() method that:

o Will alculate and return the event profit (tickets + donations expenses)

(NOTE: The profit will be negative, if the event lost money)

Tests 6 & 7 (10 pts each):

Within the EventManager class:

? Display a blank line.

? Use the Event object to call the calcEventProfit() method

? If the returned event profit is positive (including 0), display

Event generated a profit of $ 111.11

Otherwise display

Event generated a loss of $ -111.11

Test 8 (10 pts):

Within the EventManager class:

? Remove the following clause from the main method header.

throws IOException

? Implement file exception handling:

o Add a try block to catch any errors when opening the data file.

o Add a catch block to display the following message that includes the filename:

Could not open input file data.txt. Program exiting.
