We can extract the attribute value of an element in Selenium with the help of getAttribute() method. Once we locate the element, this method is used to get the attribute value of the element and assigned to a variable.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.List; public class AttributeType { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://www.tutorialspoint.com/index.htm"; driver.get(url); driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS); //Using id tagname attribute combination ...

Selenium gives Enum Key macros to perform the enter action.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.List; public class PressEnter { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = " https://www.tutorialspoint.com/index.htm"; driver.get(url); driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS); // Keys.ENTER passed through sendKeys() method driver.findElement(By.className("gsc-input")).sendKeys("Keys.ENTER"); driver.close(); } }Read More
The differences between get() and navigate() methods are listed below.sl.no.get()navigate()1It is responsible for loading the page and waits until the page has finished loading.It is only responsible for redirecting the page and then returning immediately.2It cannot track the history of the browser.It tracks the browser history and can perform back and forth in the browser.ExampleWith get().import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.List; public class LaunchBrw { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://www.tutorialspoint.com/index.htm"; ...

There are various navigate() methods to perform navigations in Selenium. They are as the listed below −navigate().to(url)This is used to launch a new browser and open a particular URL as in the parameter.navigate().refresh()This is used to reload a page.navigate().back()This is used to jump to the previous page as per browser history context.navigate().forward()This is used to jump to the next page as per browser history context.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.List; public class BrowserNavigation { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = ...

findElement() and findElements() method tries to search an element in DOM.The differences between them are listed below −sl.no.findElement()findElements()1It returns the first web element which matches with the locator.It returns all the web elements which match with the locator.2Syntax − WebElement button = webdriver.findElement(By.name(""));Syntax − List buttons = webdriver.findElements(By.name(""));3NoSuchElementException is thrown if there are no matching web elementsEmpty list is returned if there are no matching elements.ExampleUsing findElements ().import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class RowFindElements { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver ...

Xpath is one of the most important locators used in Selenium for identifying web elements. It works in the following ways −It navigates through the Document Object Model (DOM) with the help of elements and their attributes for identification.Although it helps to locate the elements uniquely, it is slower in terms of speed from the other locators.An xpath is represented by two ways namely ‘/ ‘and ‘// ‘. A forward single slash means absolute path. Here xpath traverses direct from parent to child in DOM. Thus in absolute xpath we have to travel from the root node to the target.Syntax ... Read More
Suppose we have a Binary Search Tree, we have to convert it into a Greater Tree such that every key of the original BST is changed to the original key + sum of all keys greater than the original key in BST.So, if the input is likethen the output will beTo solve this, we will follow these steps −Define a function revInorder(), this will take tree root and s, if root is null, then −returnrevInorder(right of root, s)s := s + val of rootval of root := srevInorder(left of root, s)From the main method, do the following −if root is ...

The different methods of creating a css expression are listed below −Using a class as css selectorThis will select all the web elements of that particular class. (Represented by (.) for example - .classname)Using an id as css selector.This will select the web element of that particular id. (Represented by (#) for example - #ID)Using a tagname and attribute value as selector.This will select the web element of that particular attribute value combination. (Represented by tagname [attribute=’value’])Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class CssExpression { public static void main(String[] args) { ...

We can identify the nth sub element using xpath in the following ways −By adding square brackets with index.By using position () method in xpath.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class SubElement { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://www.tutorialspoint.com/index.htm"; driver.get(url); driver.manage().window().maximize(); driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); // xpath using position() targeting the first element with type text driver.findElement(By.xpath("//input[@type='text'][position()=1]")) ...

Suppose we have an array and an integer k, we have to find the number of unique k-diff pairs in the array. Here the k-diff pair is like (i, j), where i and j are both are present in the array and their absolute difference is k.So, if the input is like [3, 1, 4, 1, 5], k = 2, then the output will be 2, as there are two 2-diff pairs in the array-like (1, 3) and (3, 5).To solve this, we will follow these steps −Define maps called seen and doneDefine one set sif k < 0, then ...
