Java method that accepts Consumer as parameter - how to use it?

Question

Is there any chance and need to use something like below ?

Could you show examples how to use function thats accepts Consumer WebElement ?

private static void methodThatAcceptsConsumer (Consumer<WebElement> consumer) {
    //something here
}

Answer 1

Consumer is an interface. You can implement it as a real class, a named nested class or as lambda.

Explicit implementation as class

class MyWebElementConsumer implements Consumer<WebElement> {
  @Override
  public void accept(final WebElement element) {
    // do something with element
  }
}

methodThatAcceptsConsumer(new MyWebElementConsumer());

Pass a lambda

methodThatAcceptsConsumer(element -> {/* do something with element */});
