CREATING AND
USING STUDENT OBJECT
AIM: To write a program
in Java to create and use objects of type Student to store the
details like Register Number, Name and Marks in Three Subjects and to
find the Total of Marks for 5 different students.
ALGORITHM:
Declare a Class named Student
that define the student object with three data members namely RegNo,
Name, and Marks. RegNo is of type int,
Name is of type String and Marks is an array of int.
Define methods setRegNo()
and getRegNo() for storing and retrieving data from RegNo
Define methods setName()
and getName() for storing and retrieving data from Name
Define methods setMarks()
and getMarks() for storing and retrieving data from Marks
array
Declare 5 objects namely stud1,
stud2, stud3, stud4 and stud5 of type Student in
method main()
Call the set methods and get
methods for each and every object for storing and retrieving data
from all five objects
