In the general case, this is impossible. A byte array can contain any amount of data, whereas a short contains exactly 16 bits.
What's in the byte array?
And do you mean a short array, rather than a short?

You will have to copy the content in to a short array by going through the elements of the byte array.

Hi,
Like Peter mentioned it could result in a possible loss of data depending on the size (no. of bits big) your data is. You can do it by iterating through the elements of the array and down-casting them.
Cheers,
Raj.

Down-casting? Isn't it the other way round; byte to short is a widening conversion?

Yes, but the original poster said he wanted to convert a "byte array" to a "short", not to a "short array".
If converting to a short array, there is no risk of data loss, as you say.

He did, but I am presuming (as you did) he meant short[]. And Raj Kamal did say iterate before downcasting so it would be byte->short.
