Java Advanced
Synchronized 2 Thread - Bài tập mảng tên + địa chỉ - Java nâng cao
Bài 1.
Cho một danh sách là họ tên các sinh viên
Ví dụ: {“Nguyen Ngoc Lan”,”Duong Tien Nam”,”Ngo Anh Quan”,”Pham Van Duc”,”Tran Thi Ha”}
Một danh sách khác là quê tương ứng của các sinh viên trên:
Ví dụ:
{“Hải Phòng”,”Hà Nội”,”Thái Nguyên”,”Hà Tĩnh”,”Quảng Ninh”}
Viết 1 ứng dụng Java sử dụng Thread để thực hiện công việc:
- Thread thứ nhất sau mỗi giây sẽ hiển thị tên 1 người tương ứng trong danh sách tên
- Thread thứ hai ngay sau đó sẽ hiển thị quê tương ứng của người đó
- Hai Thread thực hiện mỗi thread 5 lần sẽ dừng lại
Phải đảm bảo rằng Thread1 luôn được chạy trước rồi mới đến Thread2
