Using the following arrays:      
int []grades = {60, 72, 78, 95, 88, 82, 60, 97, 90, 85, 78, 75, 89, 53, 68, 83, 88, 75, 63, 94};
String []gender = {"M", "M", "F", "F", "M", "F", "F", "M", "M", "F", "F", "M", "F", "F", "M", "F", "F", "M", "M", "F"};
String []major = {"Math", "Math", "Physics", "Art", "Art", "Art", "Science", "Science", "Physics", "Art", "Math", "Math", "Math", "Science", "Science", "Physics", "Art", "Math", "Math", "Math"};
Store the three arrays in the main method. Write methods called method1, method2 and method3 to compute:
• Number of student’s in Math major.
• Total number of males in Math major.
• Total number of males in Math major who got a grade above 90 .
Return the values from the three methods back into the main methods and print from within.
