How to append a Word after a certain word in java

I have got this key value pairs under my properties file 

mailsubject = REDEX Application --- Credentials
mailtext = Dear User,\n \
          Following Are the credentials for REDEX Mapping Application  -- pwd
setFrom = [email protected]

This is where i am using them in my java file for sending email through java 

try {
        Message message = new MimeMessage(session);
        message.setSubject(props_load.getProperty("mailsubject"));
        message.setText(props_load.getProperty("mailtext") + "  " +generatedpwd);
        Transport.send(message);
        result = "success";
    } catch (MessagingException e) {
        result = "fail";
        logger.error("Exception Occured"+ "sendemalto" +sendemalto , e);
    }

My question is ,

Is it possible to insert User name after the word , so that it looks like

Dear User Kiran , Following Are the credentials for REDEX Mapping Application

    MessageFormat form = new MessageFormat("Dear {0}, following...");

    String userName = "Kiran";
    Object[] testArgs = {userName};

    System.out.println( form.format(testArgs) );

Output: "Dear Kiran, following..."

Use either String.replace(), String.replaceFirst() or String.replaceAll(), depending on what you want to do.

String.replace() replaces a given text with another one. So you can just do this:

"Dear User, Following are...".replace("User","User "+username);

Or if you need more control use String.replaceFirst() or String.replaceAll() together with a regex. replaceFirst() only replaces the first occurrence, whereas replaceAll() replaces all occurrences:

"Dear User, Following are...".replaceFirst("^Dear User"), "Dear User "+username);

Regex gives you much more control but is quite a bit more complex, so you'd need to read up on it to use it properly.

How about defining a placeholder and replacing it with your username:

props_load.getProperty("mailtext").replace("{{username}}", username)

With your template being like this:

mailtext = Dear User {{username}},\n ...
