How to replace WebDriverWait() with lambda expression?

Question

I want to know how to replace popular WebDriverWait with lambda.

It is used for explicitly wait some event.

Code snippet:

(new WebDriverWait(Driver.driver.get(), 10)).until(new ExpectedCondition<Boolean>() {
    public Boolean apply(WebDriver d) {
        return d.findElement(By.id("DataTables_Table_0_processing")).isDisplayed();
    }
});

Or:

(new WebDriverWait(Driver.driver.get(), 10))
        .until(ExpectedConditions
                .invisibilityOfElementLocated(By.id("DataTables_Table_0_processing")));

How to replace it with lambda expression?

If you're doing this in IDE, every decent modern IDE have a quick-fix or refactoring like "convert anonymous class to lambda expression". Just hit it, and you'll be fine. — Tagir Valeev

(new WebDriverWait(Driver.driver.get(), 10))
        .until(d -> d.findElement(By.id("DataTables_Table_0_processing")).isDisplayed());

I don't think the second case would be improved with a lambda since there's already a convenience method which provides sufficient clarity.

What should we use instead of WebDriverWait in Selenium 4.2 and above?
