replace special characters in string in java

Question

I want to know how to replace the string in Java.

E.g.

String a = \"adf�sdf\";

How can I replace and avoid special characters?

Answer 1

Assuming, that you want to remove all special characters, you can use the character class \p{Cntrl} Then you only need to use the following code:

stringWithSpecialCharcters.replaceAll("\\p{Cntrl}", replacement);
