Java replace method, replacing with empty character [duplicate]

Answer 1

If you just exchange single for double quotes, this will work because an empty string is a legal value, as opposed to an "empty character", and there's an overload replace(CharSequence, CharSequence). Keep in mind that CharSequence is the supertype of String.

Answer 2

try :

string.replace(".", "");

Other way is to use replaceAll :

string.replaceAll("\\.","");
