Thread thực hiện in ngẫu nhiên các số nguyên và ký tự BT1097

Tạo lớp Thread1 kế thừa Thread gồm các thuộc tính ArrayList<Integer> list1

- Thread này thực hiện sau 1s sinh ngẫu nhiên các số tự nhiêu chạy từ 0-100 -> lưu kết quả vào mảng list1

Tạo lớp Thread2 kế thừa Thread gồm các thuộc tính ArrayList<Char> list2

- Thread này thực hiện sau 2s thi sinh ngẫu nhiên các ký tự từ a-z và lưu vào mảng list2

Trong phương thức main của lớp Test tạo ra 2 thread t1 và t2 lần lượt từ Thread1 và Thread2

Khi t1 đã sinh 10 lần -> thực hiện dừng t1

Khi t2 đã sinh đc 10 ký tự thì stop t2

Sau khi 2 thread 1 và 2 kết thúc. Thực hiện in kết quả của các thread trên thread main
