This assignment has two parts:

Part 1:

1. Copy the two java files into a new Java project in your preferred IDE. Place the peopleFile.txt in the default location for your IDE (project directory NOT src for Eclipse)

2. Rename to be

3. In the main method, instead of writing the information out to a text file- open a DataOutputStream object to create a binary file named "people.dat" and use the methods of DataOutputStream to write the same information originally written in binary format to "people.dat"

4. Attach to this assignment box

Part 2:

1. Create a new class named ReadBinaryFile with a main method.

2. Use DataInputStream library class to open and read the people.dat file created in part 1.
