What is the difference between Actions and Action?

• Action is an interface in Selenium.
  It represents a single user interaction such as a mouse click, key press, or drag-and-drop operation.

• Actions is a class in Selenium that is used to build and perform complex user interactions (a chain of actions).
  It provides methods like click(), doubleClick(), moveToElement(), keyDown(), etc., which can be chained together to create a sequence of actions.

Actions usage:

WebElement element = driver.findElement(By.id(“menu”));

// Create an instance of Actions class
Actions actions = new Actions(driver);

// Build and perform a chain of actions
actions.moveToElement(element)
.click()
.doubleClick()
.contextClick()
.perform(); // Executes the built chain directly

Action usage:

// Create an instance of Actions class
Actions actions = new Actions(driver);

// Build a chain of actions and store it as an Action object
Action hoverAndClick = actions.moveToElement(element)
.click()
.build(); // returns an Action object

// Perform the built action
hoverAndClick.perform();
