Question

Accepted Answer

Selenium questions covering list vs set, findelement vs findelements, Actions class, implicit wait, and explicit wait.

List vs Set: List allows duplicate elements and maintains insertion order, while Set does not allow duplicates.
findElement vs findElements: findElement returns the first matching element, findElements returns a list of all matching elements.
Actions class: Used for performing complex user interactions like drag-and-drop, mouse movements, etc.
Syntax for Actions class: Actions actions = new Actions(driver); actions.moveToElement(element).perform();
Implicit wait: Set globally for the driver to wait for a certain amount of time before throwing a NoSuchElementException.
Explicit wait: Used for specific elements to wait until a certain condition is met before proceeding.
