How do you replace double quotes with a blank spac

问题:

For example:

"I don't like these "double" quotes"

and I want the output to be

I don't like these double quotes

回答1:

Use String#replace().

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

System.out.println("I don't like these \"double\" quotes".replace("\"", " "));

The above can also be done with characters:

System.out.println("I don't like these \"double\" quotes".replace('"', ' '));

To remove them (as per your example):

System.out.println("I don't like these \"double\" quotes".replace("\"", ""));

You don't need regex for this. Just a character-by-character replace is sufficient. You can use String#replace() for this.

String replaced = original.replace("\"", " ");

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

String replaced = original.replace("\"", "");

You can do it like this:

string tmp = "Hello 'World'";
tmp.replace("'", "");

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

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.

Strings are immutable, so you need to say

sInputString = sInputString("\"","");

not just the right side of the =
