I'm trying to get Java certified and I'd like someone to explain to me why a programmer would use shifting operators?

<<, >>, >>>

I'm learning how they work but don't know why I would use them in the real world, unless it was for encrypting a number or something.

Thanks,

Harold

// for programming in game and a large task(scientific research), fast calculation is very important.
left shift << can give you the result of being multiplied by(2^n).
3<<1 give you a result of 6.
4>>1 give you a result of 2.
