Note: According to the question, please write source code in java only using the array method. Sample Run (output) should be the same as displayed in the question below. Make sure the source code is working properly and no errors.

Exercise #1 : Design and implement a program (name it AssignGrades) that stores and processes numeric scores for a class. The program prompts the users to enter the class size (number of students) to create a single-dimensional array of that size to store the scores. The program prompts the user to enter a valid integer score (between 0 and 100) for each student. The program validates entered scores, rejects invalid scores, and stores only valid scores in the he program defines method printcrades() that takes a signal-dimensional array of integer scores as a parameter and processes the scores to print letter grades based on the following scale Grade is A if score > 90 and score 80 and score 70 and score = 60 and score
