Question

JAVA

Only need help with (D) if you can explain to me where this method needs to go? Should I place this method name ( SETNAME()) in the main method or in the gpa method ??

D) - Add one more method name it setName(), this method should read the name of student from input stream and return to main method.

Write a method to accept n integer number between 0 and 100 and return the average. B)-Write a method to convert an integer number between 0 and 100 to latter grade A to F and return. C)- Write a method to compute GPA for following letter grade and return the GPA value On Part III:     D) - Add one more method name it setName(), this method should read the name of student from input stream and return to main method.
