هذا احد الاسئله
The University is planning to have an online exam. To be sure that the student has a strong code to
login they are planning to develop a set of rules to generate the code for the student.
The developer has designed a few rules for the code. Help him to write the Java program that can
generate the code.
1) The code must not exceed 6 characters. [2]
2) The first two characters of the code must be the first two characters of the student’s id.
[Hint: Read the student’s id first.] [3]
3) The next two characters must be any two digits. [2]
4) The last two characters must be any two special characters from the list (#, $, @). [2]
5) If any one of the rules is not satisfied, prompt the user to generate the code again. [2]
6) If all the rules are satisfied then display a “Code Generated” message. [1]
