java - Using a byte array as Map key -

Do you see any problems using a byte array as a map key? I can havehed by new string (byte []) and string but it is easier to use byte [] .

The problem is that byte [] is equivalent to Object identification uses and hashode , so that

  byte [] b1 = {1, 2, 3} byte [] B2 = {1, 2, 3}  

will not match in a hashm . I see three options:

1. Wrapping in a string , but then you have to be careful about encoding issues (you have to make sure that byte -> String -> Byte gives you the same bytes.
2. Use the list & lt; byte & gt; (can be expensive in memory).
< Li> hashode and equal .

to use the contents of the byte array
