Break long page classes in many smaller classes

So you have big page classes in your project, like this one:

public class CheckOutPage {

   private static final String URL = "https://www.sell.com/checkout";

   //shipping info locators

   private static final By ADDRESS_ID = By.id("address");
   private static final By CITY_ID = By.id("city");
   private static final By PROVINCE_ID = By.id("province");
   private static final By POSTAL_CODE_ID = By.id("postalcode");

   //contact info locators

   private static final By FIRST_NAME_ID = By.id("firstname");
   private static final By LAST_NAME_ID = By.id("lastname");
   private static final By PHONE_ID = By.id("phone");
   private static final By EMAIL_ID = By.id("email");

   //order summary locators

   private static final By SUB_TOTAL_ID = By.id("subtotal");
   private static final By ORDER_DISCOUNT_ID = By.id("orderdiscount");
   private static final By ESTIMATED_SHIPPING_ID = By.id("estimatedshipping");
   private static final By ESTIMATED_TAX_ID = By.id("estimatedtax");
   private static final By ESTIMATED_TOTAL_ID = By.id("estimatedtotal");

   //continue locator

   private static final By CONTINUE_ID = By.id("continue");

   private WebDriver driver;

   public CheckOutPage(WebDriver driver) {
      this.driver = driver;
   }

   //shipping info methods

   public void typeAddress(String address) {
      WebElement field = driver.findElement(ADDRESS_ID);
      field.sendKeys(address);
   }

   public void typeCity(String city) {
      WebElement field = driver.findElement(CITY_ID);
      field.sendKeys(city);
   }
 
   public void typePostalCode(String postalCode) {
      WebElement field = driver.findElement(POSTAL_CODE_ID);
      field.sendKeys(postalCode);
   }

   public void selectProvince(String province) {
      WebElement field = driver.findElement(PROVINCE_ID);
      Select listbox = new Select(field);
      listbox.selectByValue(province);
   }

   //contact info methods

   public void typeFirstName(String name) {
      WebElement field = driver.findElement(FIRST_NAME_ID);
      field.sendKeys(name);
   }

   public void typeLastName(String name) {
      WebElement field = driver.findElement(LAST_NAME_ID);
      field.sendKeys(name);
   }

   public void typePhone(String phone) {
      WebElement field = driver.findElement(PHONE_ID);
      field.sendKeys(phone);
   }

   public void typeEmail(String email) {
      WebElement field = driver.findElement(EMAIL_ID);
      field.sendKeys(email);
   }

   //order summary methods

   public double getProductSubTotal() {
      WebElement field = driver.findElement(SUB_TOTAL_ID);
      return Double.parseDouble(field.getText());
   }

   public double getOrderDiscount() {
      WebElement field = driver.findElement(ORDER_DISCOUNT_ID);
      return Double.parseDouble(field.getText());
   }

   public double getEstimatedShippingPrice() {
      WebElement field = driver.findElement(ESTIMATED_SHIPPING_ID);
      return Double.parseDouble(field.getText());
   }

   public double getEstimatedTax() {
      WebElement field = driver.findElement(ESTIMATED_TAX_ID);
      return Double.parseDouble(field.getText());
   }

   public double getEstimatedTotal() {
      WebElement field = driver.findElement(ESTIMATED_TOTAL_ID);
      return Double.parseDouble(field.getText());
   }

   //place order methods

   public void placeOrder() {
      WebElement button = driver.findElement(CONTINUE_ID);
      button.click();
   }

   public boolean isDisplayed() {
      String url = getUrl();
      return url.contains(URL);
   }

   private String getUrl() {
      return driver.getCurrentUrl();
   }

}

Long class, isn’t it? 113 lines of code.

How can we make it smaller?
