Java and assembly?

[Pojahn_M]

If I am not mistaken, these operators are only related to assembly: << >> >>> & | ^ etc...
Is this correct?

In order to become a good programmer, should I learn how to master these and/or learn assembly programming?

There is a code I found that look like this:

sb.append(Integer.toString((mdbytes[i] & 0xff) + 0x100, 16).substring(1));
(sb is a StringBuilder).
I mean, what are those? 0xff?

I'm not amazing when it comes to bit manipulation, but that's all those operators do. They shift bits, and you have anding bits, oring bits, and I believe xoring bits.While I doubt it is necessary to be a good programmer, it certainly wouldn't hurt. I'm sure Jos, or someone a bit more advanced than Iwill be able to explain the bit manipulation stuff a bit more.
