Java code:

Suppose we have a number of students and number of grades for each student

let the user enter how many students are there, then for each student let the user enter how many grades

then read all the grades of each student and fill them in the array

Then find the average of each student and print it and print if the student pass or fail

the student will pass if the average is 50 or more and all grades are 50 or more

the student fails if any of the grades less than 50
