Iam new to selenium and trying to switch to new amazon tab which I opened and print the title
But when Sending control and Tab nothing happens how to achieve it can anyone help here :)
WebDriverManager.chromedriver().setup();
WebDriver driver = new ChromeDriver();
driver.get("https://www.amazon.com");
//Thread.sleep(6000);
Actions a = new Actions(driver);
List<WebElement> el= driver.findElements(By.xpath("(//div[#class='navFooterColHead'])[1]/../ul/li/a"));
for(int i=0;i<el.size();++i)

How to maximize selenium screen

Would anyone know how to maximize the selenium webdriver window with java and google chrome.
I already tried some commands like maximize () window () and did not work.

This is how I did it.
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(chromeOptions);

Try with this:
String chromeDriver = "/PathTo/chromedriver";
System.setProperty("webdriver.chrome.driver", chromeDriver);
ChromeDriver driver = new ChromeDriver();
//set your max dimension
java.awt.Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension dim= new Dimension((int)screenSize.getWidth(),(int)screenSize.getHeight());
driver.manage().window().setSize(dim);

//Maximizing Chrome Window.
int x=1280; //according to your screen resolution
int y=860; //according to your screen resolution
JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript("window.resizeTo(x, y);");

You can try too sending keystrokes:
SendKeys(Keys.ALT, " "); // Space, open window menu
SendKeys("x"); // Maximize
Include a pause between keystrokes, although it could work for you without it.

If you're using a Mac you'll need to use the following
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--start-fullscreen");
WebDriver driver = new ChromeDriver(chromeOptions);

You can do this using the WebDriver API, and this will work with other browsers and RemoteWebDriver:
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
https://stackoverflow.com/a/26998387/5603509

Try following code:
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized"); //This maximizes the window
options.setExperimentalOption("prefs", chromePrefs);
WebDriver driver = new ChromeDriver(options);

Exception when using headless Chrome to take screenshot of a video

I'm trying to take screenshots of a video using Selenium and Java. It works fine when I use headed Chrome, but when I want to make it headless a "java.awt.image.RasterFormatException: (y + height) is outside of Raster" is thrown in
getSubimage(point.getX(), point.getY(), eleWidth, eleHeight);
Here's the code:
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(chromeOptions);
// Get URL and find image
driver.get("https://www.webcamtaxi.com/en/netherlands/north-holland/purmerend-traffic-cam.html");
Thread.sleep(5000);
while (true) {
WebElement ele = driver.findElement(By.id("insideCam"));
// Get entire page screenshot
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
BufferedImage fullImg = ImageIO.read(screenshot);
// Get the location of element on the page
Point point = ele.getLocation();
// Get width and height of the element
int eleWidth = ele.getSize().getWidth();
int eleHeight = ele.getSize().getHeight();
// Crop the entire page screenshot to get only element screenshot
BufferedImage eleScreenshot = fullImg.getSubimage(point.getX(), point.getY(), eleWidth, eleHeight);
ImageIO.write(eleScreenshot, "png", screenshot);
}
Does someone know how to fix this?

Selenium does not recognize a new opened window

Hi all IM having troubles. My test click an hyperlynk and a new window is displayed. the problem is that when I implement windows handlers selenium only identify one window instead of 2 window and when I try to find the element of the window, well I cant cause for selenium the window never exist :(
driver.switchTo().frame(CQLo.getMframe());
WebElement Rad_CIT = (new WebDriverWait(driver,10)).until(ExpectedConditions.elementToBeClickable(CQLo.getRadCIT()));
Rad_CIT.click();
WebElement Text_CIT = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(CQLo.getTextCIT()));
Text_CIT.clear();
Text_CIT.sendKeys(citbox);
setLog("CITBox: " +citbox);
//WebElement Link_WFM =
Actions act = new Actions(driver);
WebElement onElement = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(CQLo.getLink_WFM_Admin()));
act.contextClick(onElement).perform();
act.sendKeys("o").perform();
Set <String> wind_ows = driver.getWindowHandles();
for(String sw : wind_ows)
{ System.out.println(""+sw.toString());}
setLog("Open log on " +citbox);
Thread.sleep(2000);
WebElement Text_UserN = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(Elog.getUserName()));
Text_UserN.sendKeys(MSR_name);
WebElement Text_UserP = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(Elog.getUserPassword()));
Text_UserP.sendKeys(MSR_pass);
WebElement B_logon = (new WebDriverWait(driver, 10)).until(ExpectedConditions.elementToBeClickable(Elog.getB_logon()));
B_logon.click();
after printing the SET with the windows I only receive one window

Wait some time before you get window handles after performing click on element. I think by the time you read driver window handles, new window might not be opened.

How to perform Control + Save operation with Selenium webdriver?

Am trying to save .html page into my desktop using selenium .
Can anyone pls help?

You can use the Advanced User Interactions API:
new Actions(driver)
.sendKeys(Keys.chord(Keys.CONTROL, "s"))
.perform();
This will open the Save As dialog in which you then need to navigate manually / using the Java's Robot class:
Robot robot = new Robot();
// press Ctrl+S the Robot's way
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_S);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyRelease(KeyEvent.VK_S);
// press Enter
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
Presses Ctrl+S, Enter. Beware that will not work on every system and/or browser.

JavascriptExecutor js = (JavascriptExecutor) driver;
String base64string = (String) js.executeScript("var c = document.createElement('canvas');"
+ " var ctx = c.getContext('2d');"
+ "var img = document.getElementsByTagName('img')[0];"
+ "c.height=img.naturalHeight;"
+ "c.width=img.naturalWidth;"
+ "ctx.drawImage(img, 0, 0,img.naturalWidth, img.naturalHeight);"
+ "var base64String = c.toDataURL();"
+ "return base64String;");
String[] base64Array = base64string.split(",");
String base64 = base64Array[base64Array.length - 1];
byte[] data = Base64.decode(base64);
ByteArrayInputStream memstream = new ByteArrayInputStream(data);
BufferedImage saveImage = ImageIO.read(memstream);
ImageIO.write(saveImage, "png", new File("path"));
