If you want to get Studentlist without using second method (setStudent(ArrayList<StudentEntity> studentList)) you have to add your student to your arraylist in your first method like studentList.add(student); something like this;

public class Studentform {

private StudentEntity student;
private List<StudentEntity> studentList = new ArrayList();

public StudentEntity getStudent() {
    return student;
}
public void setStudent(StudentEntity student) {
    this.student = student;
    studentList.add(student);
}
//add your list getter method here
