1. Write a program to create a file named numbers.dat, overwriting the file if it does exist. Write between 100 to 200 random integers using Random.nextInt() (the number of integers determined randomly) to the file using binary I/O. Print the sum of the integers you've written to the screen.
2. Read back the contents of the numbers.dat file that you did in Question 1 and calculate the sum. Make sure the sum you get is the same as what you got for Question 1.
3. Store the ten int values 19, 18, 17, 11, 12, 4, 7, 5, 9, and 13 inside an array. Write that array, the double value 21.5, a Date object for the current time, and the string "Hello, JVM!" to a file using binary I/O. Read back that same file and show its contents to the screen.
