(JAVA) Implement the View Exam Grades use case using the classes you determined. Each class must be implemented with the attributes and methods you defined. Assume that a file stores ten students' ID and password, and another file stores the students' ID, course number, and grade for both OOP and Software Engineering.

(IllegalArgumentException)Programming  defined the Triangle class with three sides. In the a triangle the sum of any two sides is greater then than the other side. Create IllegaTriangleException class, and modify the constructor of Triangle classto throw an IllegaTriangleException object if a triangle is created with sides that violate the rule, as follows: /** Construct a tringle the specified sides*/ public Triangle(double side1, double side2, double side3) throws IllegaTriangleException{ //Implement

(Polymorphic Banking Program Using Account Hierarchy) Develop a polymorphic banking program using the Account hierarchy created in Exercise 19.10. Create a vector of Accountpointers to SavingsAccount and CheckingAccount objects. For each Account in the vector, allowthe user to specify an amount of money to withdraw from the Account using member function debit and an amount of money to deposit into the Account using member function credit. As youprocess each Account, determine its type. If an Account is a SavingsAccount, calculate the amountof interest owed to the Account using member function calculateInterest, then add the interestto the account balance using member function credit. After processing an Account, print the updated account balance obtained by invoking base-class member function getBalance.

(in java) Add the following class methods to the program below  A method that asks for the username and password of the user. Note: Because we do not have any database, just assume all username/password combinations are valid, so set the isAuthenticated variable to true and print a login successful message inside this method with the value of isAuthenticated variable. A method that prints Top 5 Trending items in ascending order. (Use Arrays.sort() library method to quickly sort arrays). A method that prints logged in username, remaining balance and subscriber since information. A method (like updateContinueWatching(String strValue) which takes a String parameter and updates the Continue Watching array for the user. So in NetflixDemo class, take a movie or TV show name as input from the user and pass it to this updateContinueWatching(value) method. Print the final Continue Watching array. Note: New value should take first position in the Continue Watching array (index 0).…
