We need to write a Java program that allows us to calculate the average grade in a class The program will create Three Threads as follows: 1. Grades Thread: a thread that asks the user to enter the number of students. Then, it reads the grades of the students and stores them in an array and calculates the average grade. 2. CountCalculator Thread: The thread receives three parameters. The first parameter is a reference to an array of double values. The second parameter is a double value called "key". The third parameter is a Boolean called "countAbove". If countAbove is true, the thread will calculate the number of values in the array that are greater than key. Otherwise, the thread calculates the number of values that are below key. 3. Main thread: a. Creates starts and synchronizes the necessary threads. (Note that the Grade Thread

Otherwise, the thread calculates the number of values that are below key. 3. Main thread: a. Creates starts and synchronizes the necessary threads. (Note that the Grade Thread will ask the user to enter grades as described above) b. Displays the number of grades above the average and the number of grades below the average Notes: 1. You should use the join method to synchronize the threads. (Do not use semaphore) 2. It is your responsibility to know when to use the join method to get correct results in the fastest way. Sample Run: (The underlined values are entered by the user) Enter Number of Students: 5 Enter 5 grades: 80 90 70 60 80 Number of grades above average: 3 Number of grades below average: 2
