Answer to Question #202392 in Java | JSP | JSF for Shema Derrick

Question

Using java, define a class student with the following specification Private members of class student: admno integer sname string eng, math, science of type float total of type float ctotal() //a function to calculate eng + math + science with float return type. Public member function of class student: Takedata() //Function to accept values for admno, sname, eng, science and invoke ctotal() to calculate total. Showdata() //Function to display all the data members on the screen.

Answer 1
