Program 3.1 Requirements

Write/Read Test Program using RandomAccessFile and Objects

*Note you should be using methods for the code, everything should not just be dumped in the main method.

Create a new binary data file using RandomAccessFile populate it with integers from 0 to 100 Read the integer binary file and print it to the screen with 10 numbers on each line Update the integer binary file so that all of the even numbers are 2 Read the integer binary file and print it to the screen with 10 numbers on each line

Create a new binary data file using RandomAccessFile populate it with doubles from 0 to 100 Read the double binary file and print it to the screen with 10 numbers on each line Update the double binary file so that all of the odd numbers are 1 Read the double binary file and print it to the screen with 10 numbers on each line

Create a new binary data file using RandomAccessFile populate it with Strings "Hello", "Good Morning", "Good Afternoon", "Good Evening" Note: make all of the Strings the same size. Read the String binary file and print each String on it's own line Update the String binary file so that the last String says "Good Bye" Read the String binary file and print each String on it's own line

Create a new binary data file using ObjectOutputStream Use the Employee object from EmployeeManager Interface Part 1 to populate the file with the data below: 1, 100, "John", "Wayne", Employee.EmployeeType.CONTRACTOR) 2, 1000.0, "Selina", "Kyle", Employee.EmployeeType.CONTRACTOR

Create a new binary data file using RandomAccessFile Use the Employee object from EmployeeManager Interface Part 1 to populate the file with the data below: 1, 100, "John", "Wayne", Employee.EmployeeType.CONTRACTOR) 2, 1000.0, "Selina", "Kyle", Employee.EmployeeType.CONTRACTOR

Example output:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100,
