Question 1

1. Question 1 • What can happen if you don’t close a File Stream when you are done with it? • Nothing will happen since it will always close on its own • The file won’t be readable because the file will never be closed • The file may have corrupt data inside the file. • The file will never save what was written to it.

2. Question 2 • Which of the following is true? • The order of data written in a DataOutputStream and read in a DataInputStreamto the file isnt important; The program will know where to get the data we wrote. • The Order only matters as long as we use the correct variable types. • There is no reason to use FileInputStreams or FileOutputStreams except to attach higher level streams to them. • Our program needs the right order to retrieve the correct variables.

3. Question 3 • Which is the correct way to initialize the objects to use a DataInputStream? A) Create the DataInput Stream object, then attach it to a new FileInputStream object, then finally create a File object and connect them together. B)Create a File Object, then Create a DataInputStream Object and connect it directly to the File Object. C) Create a FileInputStream object, then create a DataInputStream object to connect to the FileInputStream object. We don’t need a File object because the FileInputStream object can write directly to a file. D) Create a File object. Then create FileInputStream object with the File object. After that create a DataInputStream object using the FileInputStream object.

4. Question 4 • What is a correct difference between a text and binary file type? A)You can’t store text inside a binary file. B)Binary files can’t be used on windows. C)Text file is more efficient to use than a Binary file D) Binary objects can sometimes depend on the machine (operating system, program)

5. Question 5 • Which of the following is not a valid way to take input from a file? • Use a BufferedReader • Use a Scanner • Use a DataInputStream • Use a BinaryInputStream • Use a FileInputStream
