tmp.replace("'",+"");|code-block|syntax|javascript|1100431|但这只会取代单引号。要替换双引号，必须首先对它们进行转义，如下所示：|1100432|string+tmp+=+"Hello,+\"World\"";
tmp.replace("\"",+"");|1100433|您可以将其替换为空格，也可以将其留空(我相信您希望将其留空，但您的问题标题不是这样的。|1100434|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

You can do it like this:

<pre><code>string tmp = "Hello 'World'";
tmp.replace("'", "");
</code></pre>

But that will just replace single quotes. To replace double quotes, you must first escape them, like so:

<pre><code>string tmp = "Hello, \"World\"";
tmp.replace("\"", "");
</code></pre>

You can replace it with a space, or just leave it empty (I believe you wanted it to be left blank, but your question title implies otherwise.

blocks|key|1315416|text|为此，您不需要正则表达式。只需一个字符一个字符地替换就足够了。您可以使用String#replace()来实现这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1315417|String+replaced+=+original.replace("\"",+"+");|code-block|syntax|javascript|1315418|请注意，您也可以使用空字符串""替换为。否则空间就会翻倍。|1315419|String+replaced+=+original.replace("\"",+"");|1315420|entityMap|0|LINK|mutability|MUTABLE|url|http://java.sun.com/javase/6/docs/api/java/lang/String.html#replace%2528java.lang.CharSequence,%2520java.lang.CharSequence%2529^0|10|G|10|G|0|0|0|E|2|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@$9|Z|A|10|1|11]]|E|$]]|$1|F|3|G|5|H|7|12|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|13|8|@$9|14|A|15|B|C]]|D|@]|E|$]]|$1|M|3|N|5|H|7|16|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|17|8|@]|D|@]|E|$]]]|P|$Q|$5|R|S|T|E|$U|V]]]]

You don't need regex for this. Just a character-by-character replace is sufficient. You can use <a href="http://java.sun.com/javase/6/docs/api/java/lang/String.html#replace%28java.lang.CharSequence,%20java.lang.CharSequence%29" rel="noreferrer"><code>String#replace()</code></a> for this.

<pre><code>String replaced = original.replace("\"", " ");
</code></pre>

Note that you can also use an empty string <code>""</code> instead to replace with. Else the spaces would double up.

<pre><code>String replaced = original.replace("\"", "");
</code></pre>

Use <a href="http://java.sun.com/javase/6/docs/api/java/lang/String.html#replace(java.lang.CharSequence,%20java.lang.CharSequence)" rel="noreferrer"><code>String#replace()</code></a>.

To replace them with spaces (as per your question title):

<pre><code>System.out.println("I don't like these \"double\" quotes".replace("\"", " "));
</code></pre>

The above can also be done with characters:

<pre><code>System.out.println("I don't like these \"double\" quotes".replace('"', ' '));
</code></pre>

To remove them (as per your example):

<pre><code>System.out.println("I don't like these \"double\" quotes".replace("\"", ""));
</code></pre>

blocks|key|1315508|text|字符串是不可变的，所以您需要说明|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1315509|sInputString+=+sInputString("\"","");|code-block|syntax|javascript|1315510|不仅仅是=的右侧|offset|length|style|CODE|1315511|entityMap^0|0|0|4|1|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Strings are immutable, so you need to say

<pre><code>sInputString = sInputString("\"","");
</code></pre>

not just the right side of the <code>=</code>

For example:

<pre><code>"I don't like these "double" quotes"
</code></pre>

and I want the output to be 

<pre><code>I don't like these double quotes
</code></pre>

How do you replace double quotes with a blank space in Java?

例如："I don't like these "double" quotes"我希望输出结果是I don't like these double quotes
