How to convert byte[] c# to java byte[]

Question

I have this code in C#

byte[] t = {6, 250, 215}.

But in Java is

byte[] t = {6, -6, -41}.

How to solve this problem?

c# byte and java byte are not equivalent. Java's bytes are signed. — bradimus

So if I use md5 encryption in C # I will never be able to convert in java? — Roberto Pegoraro

Both arrays are { 0b00000110, 0b11111010, 0b1101011 }. They have different interpretations. — bradimus

How to solve this problem

the 1st is read about how java represents data types..:

byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large arrays, where the memory savings actually matters. They can also be used in place of int where their limits help to clarify your code; the fact that a variable's range is limited can serve as a form of documentation.

as @bradimus statements, java's byte is an 8-bits 2 complement signed int but in C# you will never see a negative byte value

Hint:

if you consider to make a conversion...

-6 in java can be 256+(-6) = 250 in C#

and carefully consider the max and min in a java-byte if you need to convert from C# to java....
