如何从String中删除双引号字符？

Question

My server json result is "abcde" (it contains " ).

How to remove " ? This is not working.

 System.out.print(result.replaceAll("\"\",""));

Answer 1

不要使用replaceAll(String regex, String replacement)因为它接受正则表达式作为第一个参数（你不需要它），使用replace(CharSequence target, CharSequence replacement)代替：

System.out.print(result.replace("\"",""));

Answer 2

尝试使用：

System.out.println(result.replace("\"",""));

Answer 3

尝试这个：

System.out.print("abcde".replaceAll("\\"",""));

Answer 4

I am not sure why the other solutions do not work, but just for the sake of being thorough, can you check with replaceAll("\\\\\\"",""));

Since replaceAll method expects a regular expression!

Answer 5

Seeing that the other answers don't work for you, you could always remove the " manually. By removing the first character and the last one.

String str = "\"abdc\"";
str.substring(1, str.length()-1);

It a bit of a hack, not sure if has the same efficiency of replace.
