How to return an int in java

[newcoder1010]

    public class a() extends b{}
    //Caller
    Registration1.enterPhoneExt(10);
    }
    
    
    public class b() extends c{
    
         public void enterPhoneExt(int ext) {
            int randomNumber = c.GenerateRandomNumber(ext);
            driver.findElement(PhoneExtField).sendKeys(randomNumber);

     }
    
    }
    
    public class c(int Max){
    
        Random rand = new Random();
        int  n = rand.nextInt(Max) + 1;
        return n;
    }

Hello,  
    
    I am getting error in class b on line:
    

     driver.findElement(PhoneExtField).sendKeys(randomNumber);

     
     It is asking me to change the  data type of randomNumber in class b to charsequence. After I change the data type, I get another error. 
     
     Please advise on how I can return int to caller by keeping the 3 classes?

If sendKeys expects a charsequence, why are you passing an int to it?  Shouldn't you do something with that random number, like converting it to a character, before passing it to sendKeys?

So how can I convert to charsequence?

 public void enterPhoneExt(int ext) {

		int randomNumber = SuperClass.GenerateRandomNumber(ext);
		driver.findElement(PhoneExtField).clear();
		char randomNumber1 = (char) randomNumber;
		driver.findElement(PhoneExtField).sendKeys(randomNumber1);
		WaitInSeconds(1000);
}

This code makes no sense. Is this supposed to be Selenium/WebDriver stuff?

[newcoder1010]

yes

[davej]

What are you actually trying to do?

[newcoder1010]

my code has details. Simply trying to generate a random number and then enter it as phone extension. 

[davej]

Do you really need to use multiple classes and inheritance?

[newcoder1010]

Any solution will help.

Let's start with example code and then modify it. The following is from the seleniumhq.org example

public class Selenium2Example  {
    public static void main(String[] args) {
        // Create a new instance of the Firefox driver
        // Notice that the remainder of the code relies on the interface, 
        // not the implementation.
        WebDriver driver = new FirefoxDriver();

        // And now use this to visit Google
        driver.get("http://www.google.com");
        // Alternatively the same thing can be done like this
        // driver.navigate().to("http://www.google.com");

        // Find the text input element by its name
        WebElement element = driver.findElement(By.name("q"));

        // Enter something to search for
        element.sendKeys("Cheese!");

        // Now submit the form. WebDriver will find the form for us from the element
        element.submit();

        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());
        
        // Google's search is rendered dynamically with JavaScript.
        // Wait for the page to load, timeout after 10 seconds
        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.getTitle().toLowerCase().startsWith("cheese!");
            }
        });

        // Should see: "cheese! - Google Search"
        System.out.println("Page title is: " + driver.getTitle());
        
        //Close the browser
        driver.quit();
    }
}

I asked how to generate a random number and then enter it. Your example is not relevant.

This code demonstrates the use of methods, similar to what you seemed to be attempting to do. Obviously sendKeys() requires a string rather than an integer.

 

public class Newcoder0001 {
    
    public static void main(String[] args) {
        // Create a new instance of the Firefox driver
        // Notice that the remainder of the code relies on the interface, 
        // not the implementation.
        WebDriver driver = new FirefoxDriver();

        // And now use this to visit myPage
        driver.get("http://www.myPage.com");
        // Alternatively the same thing can be done like this
        // driver.navigate().to("http://www.myPage.com");

      
        enterPhoneExt(driver, 999);
     
/*
        // Now submit the form. WebDriver will find the form for us from the element
        element.submit();

        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());
        
        // Google's search is rendered dynamically with JavaScript.
        // Wait for the page to load, timeout after 10 seconds
        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.getTitle().toLowerCase().startsWith("cheese!");
            }
        });

        // Should see: "cheese! - Google Search"
        System.out.println("Page title is: " + driver.getTitle());
        
        //Close the browser
        driver.quit();
*/
    }// end of main
    
    static void enterPhoneExt(WebDriver driver, int max){
    
        WebElement element = driver.findElement(By.name("PhoneExtField")); // select element
        element.clear();
        int n = generateRandomNumber(max);
        element.sendKeys( String.valueOf(n) ); // insert int as a string
        
    }// end of method
    
    static int generateRandomNumber(int max){
    
        Random rand = new Random();
        int  n = rand.nextInt(max-1) + 1;
        return n;
        
    }// end of method
    
}// end of class
