有一个大写第一个单词字母的代码。但是，我找不到将char数组转换回String的方法：

There is a code which capitalize first word letter. However I wasn't able to find a method to convert char array back to String:

例如： hello world代码将其转换为 [ H， e， l， l， o，， W， o， r， l， d] 我想将其转换回 Hello World

For example: "hello world" code transforms it to ["H", "e", "l", "l", "o", " ", "W", "o", "r", "l", "d"] I want to transform it back to "Hello World"

public class Solution { public static void main(String[] args) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String s = reader.readLine(); char[] chars = s.toCharArray(); chars[0] = Character.toUpperCase(chars[0]); for (int i = 0; i < chars.length; i++){ if (chars[i] == ' '){ chars[i + 1] = Character.toUpperCase(chars[i + 1]); } } System.out.println(chars); } }

推荐答案

String str = String.valueOf( chars );

或

String str = new String( chars );
