Develop a GPA calculator in which the user enters the number of courses then for each course he enters the course code, grade, and hours. Use the following formula to compute the GPA where n is the number of courses. X=1 points; * hours GPA = =1 hoursi Your program should contain the following methods: /** Compute the points for a given letter grade */ public static double[] getPoints(String[] grade) /** Compute the mean of an array of double values */ public static double getGPA( double[] points, int[] hours) Here is sample run: Enter numbers of courses: 2 Enter code, grade, and hours: ICS104 A 3 MATH101 C+ 4 GPA Calculations Course Grade ICS104 A MATH101 B+ Points 3.75 3.5 Hours 3 4 The GPA is 3.61
