Need to Find Number of DropDown Options which are not selected

Need to Find Number of DropDown Options which are not selected.

URL : http://output.jsbin.com/osebed/2

TASK:

1. Select Even Option available in fruits (Banana and Orange)
2. Find out number of option not selected (Apple and Grape)

I tried it and could able to print Selected options (Banana and Orange) but cannot able to print Not Selected options (Apple and Grape)

Code:

public class Ques12 {
    public static void main(String[] args) throws AWTException {
        ChromeOptions options = new
        ChromeOptions();
        options.addArguments("--remote-allow-origins=*");
        WebDriver driver = new ChromeDriver(options);
        driver.manage().window().maximize();
        Robot robot = new Robot();
        driver.get("http://output.jsbin.com/osebed/2");
        WebElement Fruits = driver.findElement(By.id("fruits"));
        Select select = new Select(Fruits);
        select.selectByIndex(0);
        select.selectByValue("orange");

        List < WebElement > list = select.getOptions();
        List < WebElement > selectedOptions = select.getAllSelectedOptions();

        for (WebElement i: selectedOptions) {
            for (WebElement j: list) {

                if ((j.getText()).equals(i.getText())) {
                    System.out.println("Selected option " + j.getText());
                } else {
                    System.out.println("Not selected option " + j.getText());
                }
            }
        }
    }
}

Output:

Selected option Banana
Not selected option Apple
Not selected option Orange
Not selected option Grape
==========================
Not selected option Banana
Not selected option Apple
Selected option Orange
Not selected option Grape

This logic below in your code is wrong

List<WebElement> list = select.getOptions();
        List<WebElement> selectedOptions = select.getAllSelectedOptions();

        for (WebElement i : selectedOptions) {
            for (WebElement j : list) {

Simply use isSelected()and go through complete list only once to check for isSelected and print accordingly

ChromeOptions options = new ChromeOptions();
        options.addArguments("--remote-allow-origins=*");
        WebDriver driver = new ChromeDriver(options);
        driver.manage().window().maximize();
        Robot robot = new Robot();
        driver.get("http://output.jsbin.com/osebed/2");
        WebElement Fruits = driver.findElement(By.id("fruits"));
        Select select = new Select(Fruits);
        select.selectByIndex(0);
        select.selectByValue("orange");

        List<WebElement> list = select.getOptions();
        for (WebElement j : list) {

            if (j.isSelected()) {
                System.out.println("Selected option " + j.getText());
            } else {
                System.out.println("Not selected option " + j.getText());
            }
        }
        driver.quit();

Should Print

Selected option Banana
Not selected option Apple
Selected option Orange
Not selected option Grape
