如何将char数组转换回字符串？

本文翻译自：How to convert a char array back to a string?

I have a char array: 我有一个char数组：

char[] a = {'h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'};

My current solution is to do 我目前的解决方案是做

String b = new String(a);

But surely there is a better way of doing this? 但肯定有更好的方法吗？

参考：

#2楼

This will convert char array back to string: 这会将char数组转换回字符串：

char[] charArray = {'a', 'b', 'c'};
String str = String.valueOf(charArray);

#3楼

另一种方法是：

String b = a + "";

You can also use StringBuilder class 您还可以使用StringBuilder类

String b = new StringBuilder(a).toString();

Use of String or StringBuilder varies with your method requirements. String或StringBuilder的使用因方法要求而异。

A String in java is merely an object around an array of chars. java中的String只是一个字符数组周围的对象。 Hence a 因此a

char[]

is identical to an unboxed String with the same characters. 与具有相同字符的未装箱字符串相同。 By creating a new String from your array of characters 通过从您的字符数组创建一个新的String

new String(char[])

you are essentially telling the compiler to autobox a String object around your array of characters. 你基本上是在告诉编译器在你的字符数组周围自动放置一个String对象。

Try this: 试试这个：

CharSequence[] charArray = {"a","b","c"};for (int i = 0; i < charArray.length; i++){String str = charArray.toString().join("", charArray[i]);System.out.print(str);
}
