The database $($represented by $6-$array data structure$)$ consists of a set of records for the students in that class. Each student record contains the student id $($number$),$ the n $,$ the marks c$01$Tesponding to each course in that class, and a grade$$ C$-$

D$,$E$,$F$)$ that is based on the average mark being higher than $90,\text{'}\text{'}60,$ N$,$ or lower than $50,$ respectively. The number of courses is fixed $($assumed to be $3),$ while the

number of students can vary. Write ajava program to implement the following tasks:

$$ Add a full student record $($including the id$,$ name, and marks, then the average grade

should be calculated$).$

$$ Remove a full student record based on its ID$.$ This is only available after the courses

are defined; otherwise, an error message will display.

$$ Display a full student record based on student ID$.$ This task is only available after the courses are defined; otherwise, it displays a message about this exception.

$$ Find the student success rate. In case a total of $5$ marks is added, what would the

updated success rate be
