<Cucumber-JVM> pass values between steps in cucumber - selenium

Question

How do I pass the values between two steps in cucumber JVM?
In the following scenario, I want to access username provided When step in Then step.
How do I pass the values between two steps in cucumber JVM? Currently I'm accessing those by saving that value into a public variable. Is the approach correct (or) any other way I can access those between the steps?
Scenario:
Given user is on login page
When user enters username as user1 and password as pass1
And clicked on login button
Then post login page is displayed
#When("^user enters username as ([^\"]*) and password as ([^\"]*)$")
public void enterLoginDetails(String username,String password){
driver.findElement(By.id("username")).sendKeys(username);
driver.findElement(By.id("password")).sendKeys(password);
}
In the following step definition, I want to access username from the previous step definition
#Then("^post login page is displayed$")
public void postLoginValidation(){
// i would like access username and verify username is displayed
}
Thanks in Advance

Answer 1

Best Solution :
If you are using scenario outline:
When user enters username as <username> and password as <password>
Then post login page is displayed with <username>
Examples:
| username|password|
|Kiran|1234|
Step Defination Code:
#When("user enters username as (.*) and password as (.*)")
public void enterLoginDetails(String userName,String password)
{
//You will get userName=Kiran and Password=1234
}
#Then("post login page is displayed with (.*)")
public void postLoginValidation(String userName)
{
//You will be access the same username which is you are passing while login
////You will get userName=Kiran
}

Answer 2

public your class {
private String usr;
#When("^user enters username as ([^\"]*) and password as ([^\"]*)$")
public void enterLoginDetails(String username,String password){
usr = username;
...
}
#Then("^post login page is displayed$")
public void postLoginValidation(){
//do something with usr
}
}

You could share state between steps using variables, as suggested by Bala.
Another solution in Java is to use dependency injection. Cucumber-JVM support many different dependency injection frameworks.
One of them is Spring. Dependencies can be made available where they are needed using annotations. Using Spring is a good option if your project is already using Spring. Otherwise it might be too big and cumbersome.
An easy to use alternative to Spring, is to use PicoContainer.
