将字节写入 OutputStream
一次一个字节地将字节写入 OutputStream
OutputStream stream = object.getOutputStream();
byte b = 0x00;
stream.write( b );
写一个字节数组
byte[] bytes = new byte[] { 0x00, 0x00 };
stream.write( bytes );
写一个字节数组的一部分
int offset = 1;
int length = 2;
byte[] bytes = new byte[] { 0xFF, 0x00, 0x00, 0xFF };
stream.write( bytes, offset, length );
