Here is the expression

int m = -3;
m = m >>> 32;

What will be the value of m and why... please explain your answer.
Thanks

Shashank D,
Welcome to Javaranch
We'd like you to read the Javaranch Naming Policy and change your publicly displayed name to comply with our unique rule. Thank you.

As for your question - do a search in this forum. This is a common topic of discussion so you'll find lots of threads that have examples of shift operators.

Hi Shashank!
Did you try to compile and run this piece of code?
If yes, what do you think?

The value of m should still be -3. Bit shifting an int by 32 to the right is the same as not doing anything to it at all.
The general rule is: bit shifting an int by x times is equivalent to bit shifting by x % 32 (modulo 32).
 
It is sorta covered in the JavaRanch Style Guide.
