They did implement more reasonable
toStringmethods for arrays. They are located in thejava.util.Arraysclass.As for reasoning. I’m assuming by the overrides provided in the
Arraysclass, that trying to implement a generictoStringfor different types of arrays is either complex or impossible. ThetoStringmethod would have to know what type of array it was working on, and output the data approrpiately. For instance,Object[]must usetoStringon each element, whilechar[]must output the character, and the numeric datatypes must be converted to a numeric string.The methods in
Arraysget this for free, because the types are fixed due to the overrides.
