Examplei

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;

public class webdriverdemo {
   public static void main(String[] args) throws InterruptedException {
   
      WebDriver driver = new FirefoxDriver();
      
      //Puts a Implicit wait, Will wait for 10 seconds before throwing exception
      driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
      
      //Launch website
      driver.navigate().to("http://www.calculator.net/interest-calculator.html");
      driver.manage().window().maximize();
      
      //Selecting an item from Drop Down list Box
      Select dropdown = new Select(driver.findElement(By.id("ccompound")));
      dropdown.selectByVisibleText("continuously");
      
      //you can also use dropdown.selectByIndex(1) to select second element as
      //index starts with 0.
      //You can also use dropdown.selectByValue("annually");
      
      System.out.println("The Output of the IsSelected " +
         driver.findElement(By.id("ccompound")).isSelected());
      System.out.println("The Output of the IsEnabled " +
         driver.findElement(By.id("ccompound")).isEnabled());
      System.out.println("The Output of the IsDisplayed " +
         driver.findElement(By.id("ccompound")).isDisplayed());
      
      driver.close();
   }
