String name= "12E463~1.jpg";
String newName = name.replaceAll("[a-zA-Z1-90_\\- \\.]*","_");
String name has some value which contains some special characters. I want all characters apart from
A-Z
a-z
0-9
. (dot)
_ (underscore)
- (hyphen)
to be replaced with an _ (underscore)
So I should get
12E463_1.jpg in newName
But using the above regex the opposite happens. All characters apart from the special character (~ in this case) gets replaced. Please tell me how to do the opposite of the above regex.
This does not work
String newName = name.replaceAll("[^a-zA-Z1-90_\\- \\.]*","_");
