'id(java.lang.String)' in 'org.openqa.selenium.By' cannot be applied to '(org.openqa.selenium.By)'

Question

I am trying to use By in selenium as a String to get my element but it is giving me the error "'id(java.lang.String)' in 'org.openqa.selenium.By' cannot be applied to '(org.openqa.selenium.By)'"

Please assist me Here is my code:

package adta;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;

public class LoginPage extends BasePage {

    public LoginPage(WebDriver driver) {
       super(driver);
    }

    public By getUserNameLocator(){
        return By.id("user-name");

    }


    public void open(){
        driver.get("https://www.saucedemo.com/");

    }
    public boolean isLoaded(){

        return wait.until(ExpectedConditions.visibilityOfElementLocated(By.id(getUserNameLocator()))).isDisplayed();

    }


    public void login(String username, String password) {
        driver.findElement(By.id(getUserNameLocator())).sendKeys(username);
        driver.findElement(By.id("password")).sendKeys(password);
        driver.findElement(By.id("login-button")).click();
    }
}

I have tried to search for answers online but no luck

In what line, as your source code has multiple calls to By.id, some of them use output of another method as argument? — Christoph Dahlen

Since your getUserNameLocator() method returns a By type object and ExpectedConditions.visibilityOfElementLocated() method receives a By type value, you can use that inside isLoaded() method as following:

public boolean isLoaded(){

    return wait.until(ExpectedConditions.visibilityOfElementLocated(getUserNameLocator())).isDisplayed();

}
