Use String#replace().
To replace them with spaces (as per your question title):
用空格替换它们（根据您的问题标题）：
System.out.println("I don't like these \"double\" quotes".replace("\"", " "));
The above can also be done with characters:
以上也可以用字符来完成：
System.out.println("I don't like these \"double\" quotes".replace('"', ' '));
To remove them (as per your example):
要删除它们（根据您的示例）：
System.out.println("I don't like these \"double\" quotes".replace("\"", ""));

You can do it like this:
你可以这样做：
string tmp = "Hello 'World'";
tmp.replace("'", "");
But that will just replace single quotes. To replace double quotes, you must first escape them, like so:
但这只会替换单引号。要替换双引号，您必须首先对它们进行转义，如下所示：
string tmp = "Hello, \"World\"";
tmp.replace("\"", "");
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.
您可以用空格替换它，也可以将其留空（我相信您希望将其留空，但您的问题标题暗示了其他情况。

You don't need regex for this. Just a character-by-character replace is sufficient. You can use String#replace()for this.
您不需要为此使用正则表达式。只需逐个字符替换就足够了。您可以String#replace()为此使用。
String replaced = original.replace("\"", " ");
Note that you can also use an empty string ""instead to replace with. Else the spaces would double up.
请注意，您也可以使用空字符串""来代替。否则空间会翻倍。
String replaced = original.replace("\"", "");

Strings are immutable, so you need to say
字符串是不可变的，所以你需要说
sInputString = sInputString("\"","");
not just the right side of the =
不只是右侧=
