+Create a class Student with attributes name(String) and registrationNo(int) and a method show to display the attributes of the Student. Write a menu driven program with 2 choices to take the input of the student attributes and display the attributes.
+
+Input Format

+Your program should take the 2 choice as input. • If the first input will be 1 then also ask to user to enter the details of the student. If the entered registrationNo is negative, do not accept the input and prompt again to take new input until user will not entered the positive registrationNo. • If the first input will be 2 then display the default values of Student attributes separated by comma in the same line. • If the first input will be any other int value, display the message “Wrong Choice”.
