- Help of what these errors mean. In C# • Create a Class, named Student, to hold properties of Student Last Name, Student First Name, Student ID (9 digits), Course Prefix and Number, and the tests (Test 1, Test 2, Test 3, Test 4). Create appropriate setter and getter accessors, and constructors. Use access modifiers. Example: First Name : Pat Last Name : Smythe Student ID : ABC111333 Course Prefix : CIST Course Name : 2431 Test 1 : 100 Test 2 : 90 Test 3 : 80 Test 4 : 88 • Prompt the user for the Student Last and First Name, Student ID, Course Prefix and Number and the tests. • Include at least one exception handling function. • Use an array to store the 4 test grades. • Use a looping structure to populate the array. • Calculate the numeric average based upon the 4 equally-weighted numeric grades. • Display all the data for each of student using a looping structure. • Display the numeric average for each student. • Create a function that will convert the numeric average to a…It is required to develop an application in Java to perform some operations to store information about items in a store.
