Chỉnh sửa lần cuối bởi người điều hành:
cách setup và làm bài câu 2:
1. tạo sẵn 1 project = maven (ưu tiên dùng intellij vì nó gợi ý ngon) và cài sẵn dependency junit
2. Tạo 1 class mới copy toàn bộ code từ câu 2
3. Viết 1 class khác và copy code test mẫu đề cho (nếu không biết cách truyền input ntn thì code mẫu có chỉ cách truyền input)
4. Làm bài
dạ cho em hỏi mình code luôn bănq word sẽ có những rủi ro gì không ạ
Căng đấy =)) khảo thí ng ta paste vô ide của ng ta mà ko chạy là mất điểm
)) ta note y chang được cái ctrl c v vô thẳng bài làm =)))))) không thèm ghi ID Case luôn màDangQuangHuy
