blocks|key|2739275|text|不，这个解决方案是绝对正确的，而且非常简单。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2739276|但是请注意，这是一种非常不寻常的情况:因为String是在Java语言中专门处理的，所以即使是"foo"实际上也是一个String。因此，在普通代码中，不需要将字符串拆分成单独的char，然后再将它们连接起来。|offset|length|style|CODE|2739277|与C/C%2B%2B相比，在C/C%2B%2B中，"foo"的一侧是一堆以零字节结尾的char，另一侧是string，它们之间的许多转换都是使用遗留方法完成的。|2739278|entityMap^0|0|L|6|1B|5|1N|6|2H|4|0|H|5|Z|4|18|6|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]|$D|R|E|S|F|G]|$D|T|E|U|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|V|8|@$D|W|E|X|F|G]|$D|Y|E|Z|F|G]|$D|10|E|11|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|K|$]]

No, that solution is absolutely correct and very minimal. 

Note however, that this is a very unusual situation: Because <code>String</code> is handled specially in Java, even <code>"foo"</code> is actually a <code>String</code>. So the need for splitting a String into individual <code>char</code>s and join them back is not required in normal code.

Compare this to C/C++ where <code>"foo"</code> you have a bundle of <code>char</code>s terminated by a zero byte on one side and <code>string</code> on the other side and many conversions between them due do legacy methods.

<code>String text = String.copyValueOf(data);</code> 

or

A String in java is merely an object around an array of chars. Hence a

<pre><code>char[]
</code></pre>

is identical to an unboxed String with the same characters. By creating a new String from your array of characters

<pre><code>new String(char[])
</code></pre>

you are essentially telling the compiler to autobox a String object around your array of characters.

<pre><code>char[] a = {'h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'};
String b = String.valueOf(a);
System.out.println("Char Array back to String is: " + b);

<pre class="lang-java prettyprint-override"><code>String str = "wwwwww3333dfevvv";
char[] c = str.toCharArray();
</code></pre>

Now to convert character array into String , there are two ways.

<pre class="lang-java prettyprint-override"><code>Arrays.toString(c);
</code></pre>

Returns the string <code>[w, w, w, w, w, w, 3, 3, 3, 3, d, f, e, v, v, v]</code>.

And:

<pre class="lang-java prettyprint-override"><code>String.valueOf(c)
</code></pre>

Returns the string <code>wwwwww3333dfevvv</code>.

In Summary: pay attention to <code>Arrays.toString(c)</code>, because you'll get <code>"[w, w, w, w, w, w, 3, 3, 3, 3, d, f, e, v, v, v]"</code> instead of <code>"wwwwww3333dfevvv"</code>.
