How to submit a form in Selenium webdriver if submit button can't be identified?

Let us investigate the html code of element with in a form tag −

In the above example, we shall try to submit the form with the help of the Email or Password field and not by clicking on the Sign in button.

Syntax

driver.findElement(By.className("input__input")).sendKeys("96968547");
driver.findElement(By.className("session_password")).sendKeys("test123");
driver.findElement(By.className("session_password")).submit();

Example

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import java.util.concurrent.TimeUnit;
public class SubmitFrm{
   public static void main(String[] args) {
      System.setProperty("webdriver.gecko.driver",
         "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe");
      WebDriver driver = new FirefoxDriver();
      //implicit wait
      driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
      //URL launch
      driver.get("https://www.linkedin.com/");
      // identify element within form
      WebElement m=driver.findElement(By.id("session_key"));
      m.sendKeys("96968547");
      WebElement n=driver.findElement(By.id("session_password"));
      n.sendKeys("test12");
      //submit form
      n.submit();
      Thread.sleep(1000);
      System.out.println("Page title: " + driver.getTitle());
      driver.close();
   }
}
