Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method replaceAll(String, String) in the type String is not applicable for the arguments (char, char)






will be thrown because in replaceAll(‘j’,’k’) : j & k are in single quote which defines as character not as string. For correct output first replace single quote with double quotes and second write s = s.replaceAll(“j”, “k”);

Define locale.
