Change the constructor as parametrized . change student object in the main
class. Please check the code below. Let me know
If you need more help.
public class Student {
private int studentId;
private static int studentCount;
*public Student(int studentId)
{
this.studentId = studentId+1;
// this.setStudentId(studentId);
}*
public int getStudentId()
{
return studentId;
}
public void setStudentId(int Id)
{
this.studentId = Id;
}
private StudentRecord studentRecord;
public static int getStudentCount()
{
return studentCount;
}
public static void increaseStudentCount()
{
studentCount++;
}
public void setStudentName(Student s,String name)
{
studentRecord = new StudentRecord();
s.studentRecord.setName(name);
}
public String getStudentName()
{
return this.studentRecord.getName();
}
}
===========================================
public class StudentRecordExample {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
* int studId =0;
Student s1 = new Student(studId);*
s1.setStudentName(s1,"prathi");
Student.increaseStudentCount();
* Student s2 = new Student(s1.getStudentId());*
s2.setStudentName(s2,"Manu");
Student.increaseStudentCount();
*Student s3 = new Student(s2.getStudentId());*
s3.setStudentName(s3,"Shubha");
Student.increaseStudentCount();
System.out.println("The following is the list of students and their
respective details");
System.out.println("Student Name = " +s1.getStudentName());
System.out.println("Student Id = " +s1.getStudentId());
System.out.println("Student Name = " +s2.getStudentName());
System.out.println("Student Id = " +s2.getStudentId());
System.out.println("Student Name = " +s3.getStudentName());
System.out.println("Student Id = " +s3.getStudentId());
System.out.println("Total Number of Students = " +
Student.getStudentCount());
}
}
