List<String>+elephantList+=+Arrays.asList(str.split(","));|code-block|syntax|javascript|569417|基本上，.split()方法将根据您传递的分隔符(在本例中)拆分字符串，并返回一个字符串数组。|offset|length|style|CODE|569418|但是，您需要的似乎是一个字符串列表而不是一个数组，因此必须使用Arrays.asList()实用程序将该数组转换为一个列表。就像FYI一样，你也可以这样做：|569419|String+str+=+"...";

You could do this:

<pre><code>String str = "...";
List&lt;String&gt; elephantList = Arrays.asList(str.split(","));
</code></pre>

Basically the <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#split%28java.lang.String%29" rel="noreferrer"><code>.split()</code></a> method will split the string according to (in this case) delimiter you are passing and will return an array of strings. 

However, you seem to be after a List of Strings rather than an array, so the array must be turned into a list by using the <a href="http://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html#asList%28T...%29" rel="noreferrer"><code>Arrays.asList()</code></a> utility. Just as an FYI you could also do something like so:

<pre><code>String str = "...";
ArrayList&lt;String&gt; elephantList = new ArrayList&lt;&gt;(Arrays.asList(str.split(","));
</code></pre>

But it is usually better practice to program to an interface rather than to an actual concrete implementation, so I would recommend the 1st option.

blocks|key|569484|text|一个小的改进:上面的解决方案不会删除实际字符串中的前导或尾随空格。在调用split之前，最好先调用trim。而不是这个，|type|unstyled|depth|inlineStyleRanges|entityRanges|data|569485|+String[]+animalsArray+=+animals.split("\\s*,\\s*");|code-block|syntax|javascript|569486|使用|569487|+String[]+animalsArray+=+animals.trim().split("\\s*,\\s*");|569488|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

A small improvement: above solutions will not remove leading or trailing spaces in the actual String. It's better to call trim before calling split.
Instead of this,

<pre><code> String[] animalsArray = animals.split("\\s*,\\s*");
</code></pre>

use

<pre><code> String[] animalsArray = animals.trim().split("\\s*,\\s*");
</code></pre>

blocks|key|353793|text|首先，你可以像这样拆分名字|type|unstyled|depth|inlineStyleRanges|entityRanges|data|353794|String+animals+=+"dog,+cat,+bear,+elephant,giraffe";

String+animals_list[]+=+animals.split(",");|code-block|syntax|javascript|353795|访问你的动物|353796|String+animal1+=+animals_list[0];
String+animal2+=+animals_list[1];
String+animal3+=+animals_list[2];
String+animal4+=+animals_list[3];|353797|此外，您还希望删除动物名称周围的空格和逗号|353798|String+animals_list[]+=+animals.split("\\s*,\\s*");|353799|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

First you can split names like this

<pre><code>String animals = "dog, cat, bear, elephant,giraffe";

String animals_list[] = animals.split(",");
</code></pre>

to Access your animals 

<pre><code>String animal1 = animals_list[0];
String animal2 = animals_list[1];
String animal3 = animals_list[2];
String animal4 = animals_list[3];
</code></pre>

And also you want to remove white spaces and comma around animal names

<pre><code>String animals_list[] = animals.split("\\s*,\\s*");
</code></pre>

blocks|key|353895|text|有一个名为replaceAll()的函数，可以通过将所有空格替换为您想要的任何内容来删除它们。举个例子|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|353896|String+str="++15.+9+4;16.0+1"
String+firstAndSecond[]=str.replaceAll("\\s","").split(";");
System.out.println("First:"%2BfirstAndSecond[0]%2B",+Second:"%2BfirstAndSecond[1]);|code-block|syntax|javascript|353897|将为您提供：|353898|First:15.94,+Second:16.01|353899|entityMap^0|5|C|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|P|$]]

There is a function called <code>replaceAll()</code> that can remove all whitespaces by replacing them with whatever you want. As an example

<pre><code>String str=" 15. 9 4;16.0 1"
String firstAndSecond[]=str.replaceAll("\\s","").split(";");
System.out.println("First:"+firstAndSecond[0]+", Second:"+firstAndSecond[1]);
</code></pre>

will give you:

<pre><code>First:15.94, Second:16.01
</code></pre>

blocks|key|353936|text|为了完整性，使用Guava库，您应该这样做：Splitter.on(",").split(“dog,cat,fox”)|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|353937|另一个例子：|353938|String+animals+=+"dog,cat,+bear,elephant+,+giraffe+,++zebra++,walrus";

}|353941|请注意trimResults()是如何处理您的所有裁剪需求的，而不必像String.split()那样使用tweak+regexes+for+corner+cases。|353942|如果您的项目已经使用了Guava，这应该是您首选的解决方案。有关更多配置选项，请参阅Guava+User+Guide或javadocs中的拆分器文档。|353943|entityMap|0|LINK|mutability|MUTABLE|url|https://code.google.com/p/guava-libraries/|1|https://stackoverflow.com/a/20518948/56285|2|https://code.google.com/p/guava-libraries/wiki/StringsExplained#Splitter|3|http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/base/Splitter.html^0|M|11|8|5|0|0|0|0|0|G|1C|K|0|0|3|D|Z|E|1H|U|1|0|16|G|2|1N|8|3|0^^$0|@$1|2|3|4|5|6|7|18|8|@$9|19|A|1A|B|C]]|D|@$9|1B|A|1C|1|1D]]|E|$]]|$1|F|3|G|5|6|7|1E|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|1F|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|1G|8|@$9|1H|A|1I|B|C]|$9|1J|A|1K|B|C]]|D|@]|E|$]]|$1|O|3|P|5|J|7|1L|8|@]|D|@]|E|$K|L]]|$1|Q|3|R|5|6|7|1M|8|@$9|1N|A|1O|B|C]|$9|1P|A|1Q|B|C]]|D|@$9|1R|A|1S|1|1T]]|E|$]]|$1|S|3|T|5|6|7|1U|8|@]|D|@$9|1V|A|1W|1|1X]|$9|1Y|A|1Z|1|20]]|E|$]]|$1|U|3|-4|5|6|7|21|8|@]|D|@]|E|$]]]|V|$W|$5|X|Y|Z|E|$10|11]]|12|$5|X|Y|Z|E|$10|13]]|14|$5|X|Y|Z|E|$10|15]]|16|$5|X|Y|Z|E|$10|17]]]]

For completeness, using the <a href="https://code.google.com/p/guava-libraries/" rel="nofollow noreferrer">Guava</a> library, you'd do: <code>Splitter.on(",").split(“dog,cat,fox”)</code>

Another example:

<pre><code>String animals = "dog,cat, bear,elephant , giraffe , zebra ,walrus";
List&lt;String&gt; l = Lists.newArrayList(Splitter.on(",").trimResults().split(animals));
// -&gt; [dog, cat, bear, elephant, giraffe, zebra, walrus]
</code></pre>

<code>Splitter.split()</code> returns an Iterable, so if you need a List, wrap it in <code>Lists.newArrayList()</code> as above. Otherwise just go with the Iterable, for example: 

<pre><code>for (String animal : Splitter.on(",").trimResults().split(animals)) {
 // ...
}
</code></pre>

Note how <code>trimResults()</code> handles all your trimming needs without having to <a href="https://stackoverflow.com/a/20518948/56285">tweak regexes for corner cases</a>, as with <code>String.split()</code>.

If your project uses Guava already, this should be your preferred solution. See Splitter documentation in <a href="https://code.google.com/p/guava-libraries/wiki/StringsExplained#Splitter" rel="nofollow noreferrer">Guava User Guide</a> or the <a href="http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/base/Splitter.html" rel="nofollow noreferrer">javadocs</a> for more configuration options.
