Problem 1: Write a program named GradeDistribution. java, that accepts a number N from the command argument list, Use the number N to initialize an int array with the size of N, then assign a random grades to each elements of the grades array. Calculate and display the average grades.

Problem 2:
Write a program named TossingCoiSimulation. java, that accepts a number N from the Cmd argument list. Your program will generate N random numbers: either 0 or 1, then count and display the number of 0s and 1s.

Problem 3:
Write a program named CountChar. java, implement a method specified below:

public static int countChar(char c, String str)

This method counts the number of occurrence of the character c in the String str.

Then test your method as follows:

1. Pass a character and a string as arguments to the main method
2. Call countChar method
3. Print how many times the character appears in the String

For example, if you pass the argument o "Introduction to Java Program", your program should display:

The character "o" appears in the String 4 times.
