Write a program that will process an arbitrary number of grades each time the program is run. (Hints: sentinel-controlled iteration.)

Please answer 6 and 7 as they are associated altogether. 6. The FixProgram.java below has some errors.a. Fix the errors so that the program successfully compiles and runs. class FixProgram{ public static void main(String[] args) { System.out.println('Hello World!') }}  7. Change the SampleProgram.java program below.a. So that it displays Programming is fun! Instead of Hello World! class SampleProgram{ public static void main(String[] args) { System.out.println("Hello World!"); }}

Exercise 3: Write a program to simulate an experiment rolling two six sided "fair" dice. Allow the user to enter the number of rolls of the dice to simulate. What percentage of the time does the sum of the dots of the dice equal eight in the ● simulation?

Objective: Write a Java program that gives the statistics of a die being rolled some number of times! Task: . Allow the user to enter the number of times a die is rolled. Make sure to check for valid inputs, so no negative numbers. . Use a random number generator that picks only the number 1 through 6 and keep tally on each of those. Give the statistics at the end (see sample output)
