There are few places in code where manual while loop is used with Iterator to iterate over Collection. Instead of manual while cycles it's preferred to use enhanced-for cycle instead: it's less verbose, makes code easier to read and it's less error-prone. It doesn't have any performance impact: java compiler generates similar code when compiling enhanced-for cycle.
