replace character '@' in java android

Question

i want to replace character '@' and '.' to '_' from my string . I can replace char '.' to '_' but cant replace char '@' .

public String getemailparsing(String email){
        String result="";
        char keong = 64;
        for(int i=0; i<email.length();i++){
            if(email.charAt(i) == '@' ){
                result = email.replace('@', '_'); //this is NOT working
            }else if(email.charAt(i) == '.'){
                result = email.replace('.', '_'); //this one is working
            }
        }
        return result;
    }

any idea to replace char '@' ...

why you directly not replace both character instead of char loop ? when you directly replace this both character is replace if match found other noting will be replace — Haresh Chhelana, Nov 29 '14 at 05:22

Apply the little change as shown in below code. And you will get your desired output.

public String getemailparsing(String email) {
        String result = email;

        if (email.contains("@")) {
            result = result.replace('@', '_'); 
        }
        if (email.contains(".")) {
            result = result.replace('.', '_'); 
        }
        return result;
    }
