How to remove " " from java string
提问by Greg
I have a java string with " "from a text file the program accesses with a Buffered Reader object. I have tried string.replaceAll(" ","")and it doesn't seem to work.
我有一个 java 字符串，其中" "包含程序使用缓冲读取器对象访问的文本文件。我已经尝试过了string.replaceAll(" ","")，但似乎不起作用。
Any ideas?
有任何想法吗？
cleaned = cleaned.replace(" "," ");

The same way you mentioned:
与您提到的方式相同：
String cleaned = s.replace(" "," ");
It works for me.
这个对我有用。

Strings are immutable so You need to do
字符串是不可变的，所以你需要做
string = string.replaceAll(" ","")

String.replace(char, char)takes charinputs (or CharSequenceinputs)
String.replace(char, char)接受char输入（或CharSequence输入）
String.replaceAll(String, String)takes Stringinputs and matches by regular expression.
String.replaceAll(String, String)String通过正则表达式获取输入和匹配。
For example:
例如：
String origStr = "bat";
String newStr = str.replace('a', 'i');
// Now:
// origStr = "bat"
// newStr = "bit"The key point is that the return value contains the new edited String. The original Stringvariable that invokes replace()/replaceAll()doesn't have its contents changed.
关键是返回值包含新编辑的String. String调用replace()/的原始变量replaceAll()的内容没有改变。
For example:
例如：
String origStr = "how are you?";
String newStr = origStr.replaceAll(" "," ");
String anotherStr = origStr.replaceAll(" ","");
// origStr = "how are you?"
// newStr = "how are you?"
// anotherStr = howareyou?"

Strings in Java are immutable. You have to do:
StringJava 中的 s 是不可变的。你必须要做：
String newStr = cleaned.replaceAll(" ", "");

This is a two step process:
这是一个两步过程：
strLineApp = strLineApp.replaceAll("&"+"nbsp;", " ");
strLineApp = strLineApp.replaceAll(String.valueOf((char) 160), " ");
This worked for me. Hope it helps you too!
这对我有用。希望对你也有帮助！

回答by Stroev
I encountered the same problem: The inner HTML of the element I needed had " " and my assertion failed. Since the question has not accepted any answer,yet I would suggest the following, which worked for me
我遇到了同样的问题：我需要的元素的内部 HTML 有“ ”并且我的断言失败。由于该问题尚未接受任何答案，但我会建议以下内容，这对我有用
String string = stringwithNbsp.replaceAll("\n", "");
P.S : Happy testing :)
PS：快乐测试:)
