Yes. Oh wait, I wasn't supposed to say that, right? ;-)

The other posters have seems to have missed the easy way:

FileInputStream fis=...;
ByteArrayOutputStream baos=new ByteArrayOutputStream();
int n;
byte buf[1024]; // Or whatever. Larger sizes are probably more efficient.

try {
    while ((n=fis.read(buf))>0)
        baos.write(buf, 0, n);
catch (IOException x) {
    ...
}
byte result[]=baos.toByteArray();

*OR*, if you have access to the File (which you should, as you have a
FileInputStream)

File f=...;
FileInputStream fis=new FileInputStream(f);
long len=fis.length();
byte result[]=new byte[len];
long i=0, n;

try {
    while (i<len) {
        n=fis.read(result, i, len-i);
        if (n<0) break;
        i+=n;
    }
} catch (Exception x) {...}

if (i<len) { ? }
