Sorry I couldn't think of a better example for the & operator. Basically, it is used to extract individual bits from a numeric type.

As for the shift operators, in other programming languages one use for them is fast multiplication and division by powers of 2. I am not sure if that particular optimization is necessary in Java, because I am not that familiar with Java.

I believe that bit patterns are also used in Computer Graphics, Animations.

Thanx Jagdeep, now i got an idea about the usage of these from your answer. I was looking forward for Cindy's answer as her answers make the situation crystal clear.
I agree. Here's the link:
