Converting a byte[] to short[] in Java [duplicate]

Question

Possible Duplicate:
byte array to short array and back again in java

the encodeAudio() method in Xuggler has the following parameters:

int streamIndes

short[] samples

long timeStamp

TimeUnit unit

Using TargetDataLine from javax.sound.sampled I can read the data into a byte[] array

byte[] tempBuffer = new byte[10000];
fromMic.read(tempBuffer,0,tempBuffer.length);

But the problem is that the samples argument needs short[]

Answer 1

You are lucky enough that byte is "fully castable" to short, so:

// Grab size of the byte array, create an array of shorts of the same size
int size = byteArray.length;
short[] shortArray = new short[size];

for (int index = 0; index < size; index++)
    shortArray[index] = (short) byteArray[index];

And then use shortArray.

Note: as far as primitive type goes, Java always treats them in big endian order, so converting, say, byte ff will yield short 00ff.
