let's build a class SinhVien with the attributes of students created by them come up with (must list at least 3 properties), in addition the class has 4 more properties about The scores are: theory score, practical score, midterm (exam) score and final (exam) score. Besides, when any student object has just been created, the initial value of the score columns are equal to 0. Then write a program that uses the above student class and has the functions data entry for students (enter values for attributes); calculate the average score of students members (20% theory + 20% practice + 20% midterm + 40% final) and information export of students on the screen. In addition, the program must have getter and setter methods to get and set the value for all object member properties in java

public class SinhVien {
    private String hoTen;
    private int tuoi;
    private float diemHoa;
    private float diemLy;
    private float diemToan;
    private float diemTB;
    private float diemTB2;

    public SinhVien(String hoTen, int tuoi, float diemHoa, float diemLy, float diemToan, float diemTB, float diemTB2) {
        this.hoTen = hoTen;
        this.tuoi = tuoi;
        this.diemHoa = diemHoa;
        this.diemLy = diemLy;
        this.diemToan = diemToan;
        this.diemTB = diemTB;
        this.diemTB2 = diemTB2;
    }

    public String getHoTen() {
        return hoTen;
    }

    public void setHoTen(String hoTen) {
        this.hoTen = hoTen;
    }
