Regular Expression for value of the money (Java)

Do you have to catch only the value of some value of money ?

Use this simple expression, just change the value R$ for the correct money that you need take out.

String preco = precoatual.getText();

String replace = “”;
Pattern pattern = Pattern.compile(“[^0-9&&[R$]]”);
Matcher matcher = pattern.matcher(preco);
preco = matcher.replaceAll(replace);

And if the value is: R$ 124,28 – The result will are: 124,28

Simple don’t ?

Do you need scroll the page ? (Selenium and javascript)

If you need scroll the page for example take a screenshot in a browser different of Firefox (Yes, the selenium have a problem to take a screenshot of the entire page when you are in a different browser like, IE)

So we have to create a function that take a screenshot of parts of the page, and this function helps you to scroll the page.

First you have to import the libraries:

import org.openqa.selenium.JavascriptExecutor;


After the code:

JavascriptExecutor js = (JavascriptExecutor) driver;
+ “document.body.scrollHeight,document.documentElement.clientHeight));”);


After this, the driver will scroll until the end of the current page.

I hope that I help you 🙂

Mark element in the page with red border (Javascript with Selenium)

Hello again, now I will give a tip of Selenium, for mark the element that you want and before this, you can take a screenshot for evidence.

First you have to import this libraries:

import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebElement;


After this, you have to call the javascript executor and give the id or other thing for find the element:

JavascriptExecutor js = (JavascriptExecutor) driver; // change the name of your WebDriver
WebElement element = driver.findElement(“element“)); // change the localizator 

js.executeScript(“arguments[0].style.border=’3px solid red'”, element); // change the name of your variable


This is very usefull for mark the element in the page.

So, just this ! Bye bye 🙂

What a constructor do ?

Hum.. I always forget the function of a constructor because I don’t have the custom to use.

For this reason, I will put here some tips:

A constructor  is a method with instructions that will execute ALWAYS  when will instantiated a object of this class.

Like this:

  • Class
 public class MyClass {

public MyClass() { //this is the constructor method
System.out.println(“Hello World !”);
}  }

In the constructor method will be wrrte “Hello World !”

So… when you call this class, the constructor will be execute.


  • Class
 public class Test {

public static void main(String args[]) {
MyClass Obj1 = new MyClass();

It’s simple no ? It is just a method that will be execute before others methods when you call this class.
Bye bye !

How can I call the drivers(browsers) in Selenium with java ?

It’s simple !

you have to call the import > import org.openqa.selenium.WebDriver; and others about the browsers, like: import org.openqa.selenium.firefox.FirefoxDriver; (calls Firefox)

After this, in the class Main, declare driver:

WebDriver driver;

and Quit:

Quit quit = new Quit();

So… you have now choose what is the browser and calls the profile and set the configs, like proxy (for this reason you have to create a profile)

public class Main {

public static void main(String[] args) throws Exception {

FirefoxProfile profile = new FirefoxProfile();   // create a profile of Firefox
profile.setPreference(“network.proxy.type”, 0);   // Don’t use proxy
driver = new FirefoxDriver(profile);       // calls the browser with the configs of the profile
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);     // config the timeouts for load a page
driver.get(site);     // change site for the url that your driver will open.

quit.tearDown(driver);     // quit the driver.



You have to create the class that close the driver in class Main.

public class Main {

public static class Quit {

public void tearDown(WebDriver driver) {


and finish !

This is the first step for create a automation with selenium. Create a driver and open the browser !

Good studies for all, bye !
