看看这段代码会报错吗?

Question

public class test {
public static void main(String[] args)
{
char c = '';
char d = 12;
byte[] b = new byte[]{(byte) (c&0xff),(byte) (c>>8&0xff)};
System.out.println(Integer.toHexString(b[1])+":"+Integer.toHexString(b[0]));
System.out.println("");
System.out.println(d);
System.out.println(d);
}
}
