  <button onclick="myFunction1()" id="alert">simpleAlert</button>

  <p>Click the button to display a confirm box.</p>

  <button onclick="myFunction2()" id="confirm">confirmBox</button>

  <p id="demo1"></p>

  <p>Click the button to demonstrate the prompt box.</p>

  <button onclick="myFunction3()" id="prompt">prompt</button>

  <p id="demo2"></p>

  <script>
    function myFunction1() {
      alert("I am a simple alert box!");
    }

    function myFunction2() {
      var x;
      if (confirm("Press a button!") == true) {
        x = "You pressed OK!";
      } else {
        x = "You pressed Cancel!";
      }
      document.getElementById("demo1").innerHTML = x;
    }

    function myFunction3() {
      var person = prompt("Please enter your name", "PTR Nayan");

      if (person != null) {
        document.getElementById("demo2").innerHTML = "Hello " + person
            + "! How are you?";
      }
    }
  </script>

</body>
</html>

Following application clicks on all alert boxes.

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class App {

  public static void main(String[] args) throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://localhost:8080/application/");

    WebElement alertEle = driver.findElement(By.id("alert"));
    WebElement confirmEle = driver.findElement(By.id("confirm"));
    WebElement promptEle = driver.findElement(By.id("prompt"));

    alertEle.click();
    Alert alert = driver.switchTo().alert();

    System.out.println(alert.getText());
    alert.accept();

    confirmEle.click();
    alert = driver.switchTo().alert();
    System.out.println(alert.getText());
    alert.accept();

    System.out.println(driver.findElement(By.id("demo1")).getText());

    promptEle.click();
    alert = driver.switchTo().alert();
    alert.sendKeys("Hari Krishna");
    alert.accept();
    System.out.println(driver.findElement(By.id("demo2")).getText());

    Thread.sleep(9000);
    driver.quit();
