What do symbol ^ and stand for in the following script?

Question

What do symbol *^* and *>>>* stand for in the following script?
Does *(int)* means that (temp ^ (temp >>> 32) return the int format?
long temp = Double.doubleToLongBits(salary);
result = PRIME * result + (int) (temp ^ (temp >>> 32));
return result;
Thank you very much

The previous reply will help you find all you need to know.
Does *(int)* means that (temp ^ (temp >>> 32) return the int format?"format" refers to how a value is converted to text. (Sometimes how it is to be parsed as well)
"(int)" casts the long value to an int value (signed 32-bit)
long temp = Double.doubleToLongBits(salary);
result = PRIME * result + (int) (temp ^ (temp >>> 32));This will treat -0.0 as being different to 0.0. If this is undesirable, you can do something like...
long temp = aDouble != +0.0d ? Double.doubleToLongBits(aDouble) : 0L;
result = PRIME * result + (int) (temp ^ (temp >>> 32));
