Bài 4: Toán tử và biểu thức, hàm toán học trong Java

[taitinhte]

chào mọi người, mình mới học java nên có 1 số thắc mắc:
về phần toán tử quan hệ, logic và toán tử trên bit thì làm sao để phân biệt khi sử dụng, (& -- &&, | -- ||, ! -- ^)

int a [/color][color=#007700]= [/color][color=#0000bb]6[/color][color=#007700];[/color][color=#0000bb]int b [/color][color=#007700]= [/color][color=#0000bb]9[/color][color=#007700];[/color][color=#0000bb]int c [/color][color=#007700]= [/color][color=#0000bb]a[/color][color=#007700]&&[/color][color=#0000bb]b[/color][color=#007700];[/color][color=#0000bb]int d [/color][color=#007700]= [/color][color=#0000bb]a[/color][color=#007700]&[/color][color=#0000bb]b[/color][color=#007700];[/color] 

thì c =? và d=?

bạn system.out.print. .. là biết liền ^^

bạn system.out.print. .. là biết liền ^^

nó báo lỗi chỗ

[color=#000000]
int c [/color][color=#007700]= [/color][color=#0000bb]a[/color][color=#007700]&&[/color][color=#0000bb]b[/color][color=#007700];[/color] 

á bạn ơi
cái && này nó bảo là phéo toán quan hệ, mình không hiểu lắm, hôm trước ông thầy có đưa ví dụ về cái này mà ko kịp chép, bữa sau học xong ổng mới cho slide, để bữa sau mình đưa đoạn chương trình đó lên nhờ bạn giúp :d

mình cũng thấy lạ, chưa thấy ai vết như vậy, vì đây là điều kiện logic với nhau mà!

mình cũng thấy lạ, chưa thấy ai vết như vậy, vì đây là điều kiện logic với nhau mà!

thứ 4 này học xong sẽ có slide, mình post cái đoạn code đó lên, bạn xem giúp mình nha :d
