3. Write a class Student having attributes to store the following data: Name, fathers’ Name, department, degree, enrolment, seat number, marks of three subjects. Also write a class to test all methods of Student class.
Add the following methods in the above class.
• int getTotal() : This methods returns the total of marks
• void printTotal() Prints the total marks of Student
• float getPercentage() this method calculates the percentage of a student
• void printPercentatge() this method prints the percentage of student
• char getGrade() this method calculates and returns the grade.
• void printGrade() this method prints the grade of a student.
• void printInfo() This method prints all information of the
student.
private float c;
private void method2(double y) {
c = y;
}
in another class we created an object of the first class then within in it :
tester.method2 (10.0f);
are there any errors ? how many errors if there are any and with explanation please.
Create a class Rectangle. The class has attribute length and width, each of which defaults to 1. It has methods that calculate the perimeter and area of the rectangle. It has set and get methods for both length and width. The set method should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program to test class Rectangle

It has an extra day i.e. 366 instead of 365.ii. It occurs every 4 years e.g. 2008, 2012 are leap years.iii.
