How to implement Explicit Wait (WebDriverWait) in Selenium?

import org.openqa.selenium.support.ui.WebDriverWait;
import org.openqa.selenium.support.ui.ExpectedConditions;
import java.time.Duration;

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(15));

// Wait for element to be visible
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("result")));

// Wait for element to be clickable
WebElement btn = wait.until(ExpectedConditions.elementToBeClickable(By.id("submitBtn")));
btn.click();

// Wait for text to be present
wait.until(ExpectedConditions.textToBePresentInElementLocated(By.id("msg"), "Success"));

// Wait for element to disappear
wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("loader")));

// Wait for URL to contain a value
wait.until(ExpectedConditions.urlContains("/dashboard"));

// Custom wait with lambda
wait.until(d -> d.findElement(By.id("count")).getText().equals("10"));
