reate a class called “Student” with the following details:Name (should contain only alphabets –No numbers and special characters)Register Number in the format (two numbers three characters four numbers)Age (should be greater than 18 and less than 21)Phone number (10 numbers).Write appropriate Exception handling block (separate block for each type of user defined exception) to handle invalid data entry for all data items.  If the valid data is entered construct the email id and password of the student and display Email ID format:  first name four-digit year @ vitstudent.ac.in and password is “uppercase of first four characters of name + last four numbers of register number+@”

Assume that you are in the process of storing the student details of a University in a file. Code a Java application to handle the following members,Student Register Number - StringStudent Name - StringAge – IntegerGetstudents method to write details on the filePrintstudents method to display the details of the studentsIf the student age is less than 17, display a message that “Invalid Age”. Handle this exception in a proper way using one of the exception keyword.Consider storing three student details and display them.

Design a class named Person and its two subclasses named Student and Employee.  Make Faculty and Staff subclasses of Employee. A person has a name,  address, phone_number, and e-mail address. A student has a status (freshman, sophomore, junior, or senior).  An employee  has an office, salary. A faculty member has office_hours and a rank. A staff member has a title. Override the toString() method in each of these classes to display their details. Write a Java application and subsequent pseudocode to implement/simulate the same.Input :First line must read the Type of the Object(Person(P)/Employee(E)/Faculty(F)/Student(S)/Staff(T).Second line onwards read details such as name, address, phoneNo, Email and soonOutput :Print ClassName : Name, Address, PhonNo, Email, and rest of the datamembers of that class. For Example :if Type = P, then print Person : Name, Address, PhoneNo, Emailif Type = S, then print Student : Name, Address, PhoneNo, Email, Statusif Type = E, then print Employee : Name, Address, PhoneNo, Email, Office, Salaryif Type = T, then print Staff : Name, Address, PhoneNo, Email, Office, Salary, Titleif Type = F, then print Faculty : Name, Address, PhoneNo, Email, Office, Salary, Office_Hrs, RankNote :The Status for Student is freshman, sophomore, junior, or senior.Overide only toString() method in all the Classes.

Write a query to display the number of students having invalid email id.The valid email ids should have “@” anywhere after the first character and should end with “.com”. Give an alias name for the count as ‘student_count’.

In a College student needs to pay fee, create a class ‘Student’ and get the name, age, Department, Last date for fee payment, current date and Penalty-per-day information. For ‘age’ create user defined exception class and check if age is a negative number and print “Please enter correct age”. Calculate the total penalty as days* penalty-per-day. If the total number of days exceeded 5 handle the exception and print “Not Permitted”.If the name entered is not a string, then handle it using exception handling and print “Enter your Correct Name”. Input:Anne18CSE2022-10-05(last date)2022-10-12(current date)2000(penalty per day)OutputNot Permitted
