How to use a return string of another class using Java?

Question

I'm using the follow code to generate random e-mails on the dataMap class:

public static String generateRandomEmail(int length) {

            String allowedChars = "abcdefghijklmnopqrstuvwxyz" + "_-.";
            String email = "";
            String temp = RandomStringUtils.random(length, allowedChars);
            email = temp.substring(0, temp.length() - 1)+"@mailinator.com";
            System.out.println(email);
            return email;    
        }

On my steps class, I need to use this email value, but I'm calling the method again, so it's generate another "email".

@Dado("que realizo a chamada no (.*) da (.*) informando (.*) e um email e (.*) novos")
        public void verificarAmbiente(String srtAmbiente, String srtAPI, String srtToken, String srtSenha) {
            System.out.println(srtAmbiente+srtAPI);
            dataMap data = new dataMap();
            int length = 15;
            data.generateRandomEmail(length);
            Map<String, String> emailContent = new HashMap<String,String>();
            emailContent.put("email", data.generateRandomEmail(length));
            Map<String, Object> postContent = new HashMap<String,Object>();
            postContent.put("customer", emailContent);
            postContent.put("password", srtSenha);
            given().contentType(ContentType.JSON)
                .header("Authorization", "Bearer "+srtToken)
                .with().body(postContent)
                .when().post(srtAmbiente+srtAPI).prettyPeek()
                .then().statusCode(200);

        }

I wanna transform the "return email" in a variable and call it in another class without execute the method again and change the value. Can you help me? Thanks!

Instead of just having data.generateRandomEmail(length); do String email = data.generateRandomEmail(length); and then use email the second time around. — Federico klez Culloca

If you want random email each time, you will have to execute the same block of code again and again. — Aniket Sahrawat

The first call to generateRandomEmail is not needed at all, as it doesn't change any state. It just generates the email, returns it, but the return value is thrown away — igorepst

You need to store the generated email in a variable:

String email = data.generateRandomEmail(length);

And then you can just use the email variable later when you need the same email address.
