You can use String.valueOf(char[]):

您可以使用String.valueOf(char[])：

String.valueOf(c)

Under the hood, this calls the String(char[])constructor. I always prefer factory-esque methods to constructors, but you could have used new String(c)just as easily, as several other answers have suggested.

在幕后，这会调用String(char[])构造函数。与构造函数相比，我总是更喜欢工厂式的方法，但是您可以new String(c)像其他几个答案所建议的那样轻松地使用它。
