how to make multiple line string to single line string?
I have below string
String str="select * from m_menus;
select * from m_roles";
I want above string in one line
like
String str="select * from m_menus;select * from m_roles";
I have tried
str1=str.replace("[rn]+", " ");
and also
str1=str.replace("n"," ");
Both are not working.

Stupid question.. but why don't you just do this in the first place?:String str="select * from m_menus;select * from m_roles";Is it really the string that's the problem or are you passing it to a SQL engine and getting results you're not happy with.

If you want to use regex, you should use the String.replaceAll() method.

No regular expressions and operating system independent:
str1.replaceAll(System.lineSeparator(), " ");
Windows uses rn as a line breaker, while *nix systems use only n.
