Java Basic

Java Basic- Overview - Tổng hợp bài tập ôn luyện java basic - Kiểm tra 60 phút

Bài 1: Tính tổng các số nguyên từ 0->N (N được nhập từ bàn phím)

Bài 2: Nhập vào mảng số nguyên gồm N phần tử (N được nhập từ bàn phím) -> In ra các số chia hết cho 2

Bài 3 : Tạo lớp đối tượng Book gồm các thuộc tính sau

- tên sách, tác giả, nhà sản xuất, năm sản xuất

-Viết getter/setter và 2 hàm tạo

- Viết hàm nhập/hàm hiển thị

- Tạo 2 đối tượng Book với 2 hàm tạo tương ứng trong phương thức main của lớp test. Nhập và hiển thị thông tin sách

Bài 4 :

Tạo lớp People gồm các thuộc tính : tên, địa chỉ

- tạo hàm nhập và hiển thị thông tin sinh viên

Tạo lớp Student kế thừa từ lớp People và có thêm các thuộc tính rollNo

- Ghi đè 2 phương thức nhập và hiển thị thông tin sinh viên

Tạo 2 đối tượng People và Student trong phương thức main của lớp Test. Thực hiện nhập và hiển thị thông tin của 2 đối tượng trên.

Bài 5:

Tạo lớp Vehicle gồm 3 phương thức abstract : running, input, display

Tạo lớp Car kế thừa từ lớp Vehicle có thuộc tính name, số bánh xe.

- Viết các hàm input và display và running (hàm running sẽ hiển thị dòng Car is running)

Tạo lớp BikeCycle kế thừa từ lớp Vehicle có thuộc tính name, số bánh xe

- Viết các hàm input và display và running (hàm running sẽ hiển thị dòng BikeCycle is running)
