I want to replace /r/n in above string with empty string with following restrictions. 1. Don't not replace /r/n if its exists only once (Ex: /r/n) 2. Replace if multiple /r/n (Ex: /r/n/r/n/r/n/r/n then replace with empty string.
Example String "\r\n\r\n\r\n\r\nCovered. Coverage is limited to a\r\n one-time only 7095 for one outpatient\r\n\r\n\r\n";
Expected Output: Covered. Coverage is limited to a\r\n one-time only 7095 for one outpatient
I would write something like this:
my_str = my_str.replaceAll("(\r\n){2,}", "");
Hope that helps.
