I'd suggest to use ArrayList[^].

Java

class InputStudentInfo {
 
    //
    public void main (String[] args)
    {
        //declare ArrayList to store students list
        ArrayList<studentInfo> students = new ArrayList<studentInfo>;

        StudentInfo student = new StudentInfo();
        //1
        student.studentName = "Justin Lazaro";
        student.barrowedBooks = ("English, Math");
        //add to list
        students.Add(student);     
        //2	
        student = new StudentInfo();
        student.studentName = "Gian Acuna";
        student.barrowedBooks = "Math";
        students.Add(student);
        //etc.

        //further...
        // use for(...) loop
        // to iterate through the collection of student
    }
}

For further information, please see: The for-each loop[^]

By The Way: Why do you declare date as as a string?

Java

String date;
String expiredDate;

Java knows date data type[^].
