1 : 0);. It is also presumably safe to use a subtraction– on 32-bit architecture at least, it's impossible to have Java Strings long enough to overflow when doing the subtraction! If you enjoy this Java programming article, please share with friends and colleagues. Follow the author on...
1. When to Use Comparator Interface JavaComparatorinterface imposes atotal orderingon the objects which may not have a desired natural ordering. For example, for aListofEmployeeobjects, the natural order may be ordered by employee’s id. But in real-life applications, we may want to sort the...
