While printing xy coordinates of webelement using Selenium web-driver getting java.lang.NumberFormatException

Question

Below is my sample code that take from this Stackoverflow question Not able to drag element using Actions

Sample code that used to find the webelement XY cordinates. By getting error "org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died."

Or in the error printed on the eclipse console getting "Caused by: java.lang.NumberFormatException: For input string: "617.7"

    WebDriver browser = new ChromeDriver();
browser.get("http://www.seleniumeasy.com/test/drag-and-drop-demo.html");

// Robot class uses Screen Coordinates, therefore, we need the fullscreen browser 
// instead of maximised. so that the webpage coordinates are mapped to screen
// coordinates.
browser.manage().window().fullscreen();

WebElement itemToBeDragged = browser
            .findElement(By.xpath(" (//h3[contains(.,'Items to Drag')]//following-sibling::span)[1]"));
WebElement whereToBeDragged = browser.findElement(By.xpath("//div[@id='mydropzone']"));

// robot class object to perform actual mouse events.
// import java.awt.Robot and java.awt.event.InputEvent
Robot robot = new Robot();

try {
         robot.mouseMove(itemToBeDragged.getLocation().x+(int)itemToBeDragged.getSize().width/2, itemToBeDragged.getLocation().y+(int)itemToBeDragged.getSize().getHeight()/2);
          Thread.sleep(1000);
          robot.mousePress(InputEvent.BUTTON1_DOWN_MASK);
          robot.mouseMove(itemToBeDragged.getLocation().x+(int)itemToBeDragged.getSize().width/3, itemToBeDragged.getLocation().y+(int)itemToBeDragged.getSize().getHeight()/3);
          Thread.sleep(1000);


          Thread.sleep(1000);
          robot.mouseMove(whereToBeDragged.getLocation().x+(int)whereToBeDragged.getSize().width/3, whereToBeDragged.getLocation().y+(int)whereToBeDragged.getSize().getHeight()/3);

          Thread.sleep(1000);
          robot.mouseMove(whereToBeDragged.getLocation().x+(int)whereToBeDragged.getSize().width/2, whereToBeDragged.getLocation().y+(int)whereToBeDragged.getSize().getHeight()/2);


        Thread.sleep(1000);
        robot.mouseRelease(InputEvent.BUTTON1_MASK);

        Thread.sleep(1000);
    } catch (Exception e) {
        e.printStackTrace();
    }

Below is my Error what i get in Eclipse Console.

mouseMove() method takes integer as the variable, however you are using the division method on the dimensions which would be returning a double/float value due to which you are getting NumberFormatException.
To resolve the issue, you need to typecast those values to int.

You can do it like:

robot.mouseMove(robot.mouseMove(itemToBeDragged.getLocation().x+(int)itemToBeDragged.getSize().width/2), itemToBeDragged.getLocation().y+(int)itemToBeDragged.getSize().getHeight()/2));

You need to append (int) before every value in which you are using a division method.
