Binary IO java help thanks

[10 marks] Write a Java program to track how many times the program has been executed. You can store an int representing the count in a file, e.g., count.dat. Each time your program is executed, read the count, increment it by 1, and then store it back to the file. If count.dat doesn't exist (e.g., first time to run the program), store 1 in the file. Use binary IO for your code. For this question, just write your code in the main method and declare the checked exceptions in the method's header [10 marks] Write a Hex Viewer method with the following header: private static void viewHex (String filename) The method reads bytes from filename and displays them in hex representation. The output should be formatted as in the example below, i.e., 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 a try statement to handle IOException and display a simple error message if an I/O exception occurs.
