class ByteUShift {   static public void main(String args[]) {     char hex[] = {       '0', '1', '2', '3', '4', '5', '6', '7',       '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'     };     byte b = (byte) 0xf1;     byte c = (byte) (b >> 4);     byte d = (byte) (b >>> 4);     byte e = (byte) ((b & 0xff) >> 4);       System.out.println("              b = 0x"       + hex[(b >> 4) & 0x0f] + hex[b & 0x0f]);     System.out.println("         b >> 4 = 0x"       + hex[(c >> 4) & 0x0f] + hex[c & 0x0f]);     System.out.println("        b >>> 4 = 0x"       + hex[(d >> 4) & 0x0f] + hex[d & 0x0f]);     System.out.println("(b & 0xff) >> 4 = 0x"       + hex[(e >> 4) & 0x0f] + hex[e & 0x0f]);   } }

Output of Above Java Program

              b = 0xf1
         b >> 4 = 0xff
        b >>> 4 = 0xff
(b & 0xff) >> 4 = 0x0f
