how to replace the \n in java?

Question

I have working in Facebook for my app in Android. I have to use the string to pass as a url. But my description value has a lot of spaces and line breaks. I have to rectify while passing that value as url without spaces. But it will poste on the facebook wall with the spaces. Is it possible? Any Idea.

Answer 1

生成URL参数时，请使用：

paramString = URLEncoder.encode(paramString, "utf-8");

Answer 2

I'm not sure if you're asking how to properly encode the URL so it has no whitespace, or if you want to remove line breaks from a string. If you want to remove line breaks from a string, do this:

yourString.replaceAll("\n", "");
