Exception: An exception is a problem that creates during the execution of a program; it offers a method to transfer control from one part to another part of a program. An exception handling is created by using the following three keywords such as try, catch and throw. The “try” block have the program for the basic algorithm that says the computer what to do when all goes well. The “throw” keyword throws an error statement to the “catch” block. The “catch” block will catch the exception or handling the exception. Generally, the compiler executes “try” block. In the “try” block, if the statements cause an exception, it throws an error statement to the “catch” block using the keyword “throw”. The “catch” block then handles the error based upon the type of exception.

The program should place the code into a try-catch block with multiple catches to check for the validity of various attributes based on the following criteria. a. Student ID must start with a letter and should be followed by four digits. b. The default number of courses must be at least 3. -Print suitable error matches within the catch block. If any of the criteria mentioned above is not fulfilled, the program should loop back and let the user enter new data. -Add methods for the number of courses registered and withdrawn. Create your own exception class which will check inside the method for the courses registered so that after the registration, the maximum number of registered courses should not be more than 6.
