Hi Friend,

Try the following code:

import java.util.*;

class Student {
public Student(String n, double s, int year, int month, int day){
name = n;
marks = s;
GregorianCalendar calendar = new GregorianCalendar(year, month - 1, day);
admissionDate = calendar.getTime();
}
public String getName(){
return name;
}
public double getMarks(){
return marks;
}
public Date getAdmissionDate(){
return admissionDate;
}
public void raiseMarks(double p){
double raise = marks * p / 100;
marks += raise;
}
private String name;
private double marks;
private Date admissionDate;
}
public class ArrayListExample{
public static void main(String[] args){
ArrayList<Student> student = new ArrayList<Student>();
student.add(new Student("A", 90, 2001, 10, 15));
student.add(new Student("B", 95, 2002, 7, 1));
student.add(new Student("C", 85, 2003, 4, 15));
student.add(new Student("D", 80, 2004, 8, 1));
for (Student s : student)
s.raiseMarks(5);
for (Student s : student)
System.out.println("Name=" + s.getName() + " Marks=" + s.getMarks() + " Admission Date="+ s.getAdmissionDate());
}
}

Hope that it will be helpful for you.
Thanks
