-Informs you when bitwise operations can be replaced with the Long.hashCode() or Double.hashCode() method.
- It detects instances of the pattern (int)(x ^ (x >>> 32)) where x is a variable of type long or
- the result of the previous Double.doubleToLongBits() call. This replacement shortens the code improves its readability.

- Example: -
+Reports bitwise operations that can be replaced with a call to theLong.hashCode() or Double.hashCode() methods.
+It detects the construct (int)(x ^ (x >>> 32)) where x is a variable of type long or
+the result of a previous Double.doubleToLongBits() call. The replacement shortens the code, improving its readability.
+Example:
-int result = (int)(var ^ (var >>> 32));
+ int result = (int)(var ^ (var >>> 32));
After applying the quick-fix:
-int result = Long.hashCode(var);
+ int result = Long.hashCode(var);
