Sanity4J was created to simplify running multiple static code analysis tools on the Java projects. It provides a single entry point to run all the selected tools and produce a consolidated report, which presents all findings in an easily accessible manner.

The newest version!



DM_FP_NUMBER_CTOR

Bx: Method invokes inefficient floating-point Number constructor; use static valueOf instead (DM_FP_NUMBER_CTOR)

Using new Double(double) is guaranteed to always result in a new object whereas
Double.valueOf(double) allows caching of values to be done by the compiler, class library, or JVM.
Using of cached values avoids object allocation and the code will be faster.


Unless the class must be compatible with JVMs predating Java 1.5,
use either autoboxing or the valueOf() method when creating instances of Double and Float.
