…() method. 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. http://findbugs.sourceforge.net/bugDescriptions.html#DM_FP_NUMBER_CTOR
