1.Write a Java program to track how many times the program has been executed. You will store the number (integer) representing the count into a file (count.dat). If the count.dat doesnt exist (e.g., first time to run the program), store 1 in the newly created file. You will use binary IO (FileInputStream / FileOutputSteam) for your code. For this question, you will also need to declare the checked exceptions in the methods header to handle errors. Since the counter.dat file is a binary file (you cannot read it with your typical text editor(eg MS words), you can use your Hex viewer method program from the following question to open the file to examine the contents. If you are using notepad++, you can also download the HexEditor plugin to enable the Hex view

2.

Write a Hex Viewer method with the following header to read a binary file.

private static void viewHex(String filename)

This method reads bytes from the file (data.dat, and your counter.dat from the previous question) and displays them in hex representation. The output should be formatted as shown in the example below. Each line consists of 8 pairs of hex numbers, then |, then another 8 pairs. Use Integer.toHexString( ) to convert a byte into a string representing the equivalent hex. Use try statement to handle IOException and display a simple error message if an I/O exception occurs.
