NullPointerException when adding elements into a List in Java/Selenium

RahulShettyAcademy

I want to add the elements(Veg/Fruit name) into a List and want to print the list by clicking on "Next" Button, but I am getting error as: java.lang.NullPointerException, at the line veggieList1.add(element);

CODE:

    public void seleniumStream1() {
    System.setProperty("webdriver.chrome.driver", "C:\\Drivers\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    driver.get("https://rahulshettyacademy.com/seleniumPractise/#/offers");
    WebDriverWait wait = new WebDriverWait(driver, 15);
    WebElement next1 = driver.findElement(By.cssSelector("[aria-label='Next']"));
    List<WebElement> veggieList1 = null;

    for (int i = 0; i < 4; i++) {

        List<WebElement> veggies1 = driver.findElements(By.xpath("//tbody/tr/td[1]"));

        for (WebElement element : veggies1) {
            veggieList1.add(element);
        }

        if (next1.getAttribute("aria-disabled").equalsIgnoreCase("false")) {
            next1.click();
        }
    }

    for (WebElement element1 : veggieList1) {
        System.out.println(element1.toString());
    }
    driver.close();
}

You are initializing the veggieList1 to null on line List<WebElement> veggieList1 = null;. You should use List<WebElement> veggieList1 = new ArrayList<>(); if you wish to initialize this variable with an empty list.
