1. Can you use writeInt to write a number to a file and then read that number using readLong? Can you read that number using readDouble?

2. Write a complete Java program that asks the user for the name of a binary file and writes the first data item in that file to the screen. Assume that the first data item is a string that was written to the file with the method writeUTF.

3. Does the class FileInputStream have a method named readInt? Does it have one named readDouble? Does it have one named readUTF?

ObjectInputStream inputStream = new
