What is the way to get a list of options that can be selected from a dropdown using Selenium and Java?

I want to get a list of all the options that can be selected from a dropdown menu in selenium using java. How can I do that?

Use this method
getAllSelectedOptions()
Refer this site for more information
https://www.codota.com/code/java/methods/org.openqa.selenium.support.ui.Select/getAllSelectedOptions

There are multiple approaches to print the texts from the option elements of a drop-down-menu. Ideally while interacting with a html-selct you need to use the Select Class. Further to interact with all the <option> tags you need to use getOptions() method. As an example to print the texts from the Day, Month and Year option elements within facebook landing page https://www.facebook.com/ you you need to use WebDriverWait for the elementToBeClickable() and you can use the following Locator Strategies.
Options from Day Dropdown using id attribute:
WebElement dayElement = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.id("day")));
Select selectDay = new Select(dayElement);
List<WebElement> dayList = selectDay.getOptions();
for (int i=0; i<dayList.size(); i++)
System.out.println(dayList.get(i).getText());
Options from Month Dropdown using xpath and java-8 stream() and map():
Select selectMonth = new Select(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//select[#id='month']"))));
List<String> myMonths = selectMonth.getOptions().stream().map(element->element.getText()).collect(Collectors.toList());
System.out.println(myMonths);
Console Output:
[Month, Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sept, Oct, Nov, Dec]
Options from Month Dropdown using [tag:css_selectors] and java-8 stream() and map() in a single line of code:
System.out.println(new Select(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("select#year")))).getOptions().stream().map(element->element.getText()).collect(Collectors.toList()));
Console Output:
[Year, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, 2011, 2010, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997, 1996, 1995, 1994, 1993, 1992, 1991, 1990, 1989, 1988, 1987, 1986, 1985, 1984, 1983, 1982, 1981, 1980, 1979, 1978, 1977, 1976, 1975, 1974, 1973, 1972, 1971, 1970, 1969, 1968, 1967, 1966, 1965, 1964, 1963, 1962, 1961, 1960, 1959, 1958, 1957, 1956, 1955, 1954, 1953, 1952, 1951, 1950, 1949, 1948, 1947, 1946, 1945, 1944, 1943, 1942, 1941, 1940, 1939, 1938, 1937, 1936, 1935, 1934, 1933, 1932, 1931, 1930, 1929, 1928, 1927, 1926, 1925, 1924, 1923, 1922, 1921, 1920, 1919, 1918, 1917, 1916, 1915, 1914, 1913, 1912, 1911, 1910, 1909, 1908, 1907, 1906, 1905]

This approch might help you to get understand how to get all selectable options from dropdown
driver.navigate().to("https://the-internet.herokuapp.com/");
WebDriverWait wait = new WebDriverWait(driver,10,100);
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//a[#href='/dropdown']"))).click();
WebElement element = driver.findElement(By.xpath("//select[#id='dropdown']"));
Select select = new Select(element);
List<WebElement>allOptions = select.getOptions();
allOptions.forEach(value->{System.out.println(value.getText());});

Gregorian Calendar JavaFX

I am stuck trying to figure out this question. It is about JavaFX control choosing the name of the day for the month, number day and year when pressing enter.. I even tried using object oriented to solve the problem. The question is in a picture link. Here is the question in this link.
New EDIT and Code: I am off by one day for getting the day of the week for example January 1, 2012 should be day 1 as the answer in console: Day of Week: 1 not 2.
public class DayOfWeek extends Application {
private String[] months = { "JANUARY", "FEBRUARY", "MARCH", "APRIL", "MAY", "JUNE", "JULY", "AUGUST", "SEPTEMBER",
"OCTOBER", "NOVEMBER", "DECEMBER" };
private String[] days = { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16",
"17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31" };
String s1 = "";
int k = 0;
String s2 = "";
int x = 0;
#Override
public void start(Stage primaryStage) {
// add a gridpane
GridPane grid = new GridPane();
grid.setPadding(new Insets(10, 10, 10, 10));
// add a label for original message top left side
Label label1 = new Label("Month: ");
GridPane.setConstraints(label1, 0, 0);
ListView<String> lv = new ListView<>(FXCollections.observableArrayList(months));
lv.setPrefSize(100, 100);
lv.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
GridPane.setConstraints(lv, 1, 0);
Label label2 = new Label("Day: ");
GridPane.setConstraints(label2, 2, 0);
ListView<String> lvdays = new ListView<>(FXCollections.observableArrayList(days));
lvdays.setPrefWidth(50);
lvdays.setPrefHeight(75);
lv.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
GridPane.setConstraints(lvdays, 3, 0);
Label label3 = new Label("Year: ");
GridPane.setConstraints(label3, 4, 0);
TextField textfield3 = new TextField();
GridPane.setConstraints(textfield3, 5, 0);
lv.setOnMouseClicked(e -> {
s1 = lv.getSelectionModel().getSelectedItem();
k = lv.getSelectionModel().getSelectedIndex();
System.out.println(lv.getSelectionModel().getSelectedItem());
});
lvdays.setOnMouseClicked(e2 -> {
s2 = lvdays.getSelectionModel().getSelectedItem();
x = lvdays.getSelectionModel().getSelectedIndex();
System.out.println(lvdays.getSelectionModel().getSelectedItem());
});
textfield3.setOnKeyPressed(e3 -> {
if (e3.getCode() == KeyCode.ENTER) {
GregorianCalendar cal2 = new GregorianCalendar(textfield3.getLength(), k, x);
System.out.println("Day of Week: " + cal2.get(Calendar.DAY_OF_WEEK));
}
});
// add it to the parent
grid.getChildren().addAll(label1, lv, label2, lvdays, label3, textfield3);
// set a scene and place show it
Scene scene = new Scene(grid, 600, 200);
primaryStage.setTitle("Day of Week");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}

First, don’t fill strings into your list views. Fill the month list view from Month.values() and the days of the month with Integer objects. This will be more convenient when taking the selected item out and will save you of declaring the arrays at the top of the class.
In the following I am assuming that instead of s1 you have a variable named m of type Month for the month and s2 has type Integer (you should find a better name).
String yearText = textfield3.getText();
try {
int year = Integer.parseInt(yearText);
LocalDate date = LocalDate.of(year, m, s2);
System.out.println("Day of Week: " + date.getDayOfWeek());
} catch (NullPointerException | NumberFormatException | DateTimeException e) {
System.out.format("Not a valid date: %s %s %d", yearText, m, s2);
}
Avoid using GregorianCalendar. That class was poorly designed and is fortunately long outdated. Instead use LocalDate from java.time, the modern Java date and time API.
Opposite the GregorianCalendar constructor the LocalDate.of method will throw an exception if you pass invalid values to it, such as for example 29 of February 2019. This will help you report the invalid date to the user as required.
What went wrong in your code?
You were using textfield3.getLength() for the year. Assuming a four digit year was entered this would give you year 4 (that’s a couple of millennia ago now).
When you used lvdays.getSelectionModel().getSelectedIndex() for the day of month, you got the 0-based index in the list in the list view. So when the user picked 1 you were getting 0, etc.
Other tip: Learn to invent good variable names. It really makes the difference between valuable and worthless code. Also when asking a question on Stack Overflow, people will be more likely to help you if they can read your code easily, which they cannot with the variable names s1, s2, k and x.

I have crawled 500K webpages and stored them in a Json file. Now, I am trying to read it. The whole file is 2GB, so I am unable to share the whole file.
I understand Json parser is getting some unexpected character (s) in the file but I am unable to find which line in the json file is erroneous. Is there any way I can find out the faulty line in the json file?
Edit
Main code in processing webpage contents is as follows.
for (Element element : elements) {
String tagName = element.tagName();
if (Util.isValidTag(tagName)) {
String textValue = Util.removeNonPrintableChars(element.ownText()).trim().replace("\"", "\'");
if (!textValue.isEmpty()) {
if (tagTextMap.containsKey(tagName)) {
tagTextMap.get(tagName).add(textValue);
} else {
ArrayList<String> arr = new ArrayList<>();
arr.add(textValue);
tagTextMap.put(tagName, arr);
}
}
}
}
I just removed non-printable characters and also replace double quotes by single quote, that's it.
Update
I found the problematic section in the json file.
{
"url": "http://www.kudzu.com/",
"title": "Atlanta roofers, hvac, plumbers, electricians and other businesses - reviews, coupons and cost estimates from your neighbors.",
"content": {
"h2": ["From Our Experts", "Recent Projects", "Recent Articles", "What It Costs", "Review a Business", "What It Costs", "Other Markets"],
"body": ["\"],
"span": ["Area", "Area", "Cost"]
}
}
This part - "body": ["\"], is the source of problem. I can understand now why its causing the problem.

It seems you are having trouble with escaping special characters. See this list of special characters used in JSON :
\b Backspace (ascii code 08)
\f Form feed (ascii code 0C)
\n New line
\r Carriage return
\t Tab
\" Double quote
\ Backslash character
So, while dumping json you need to escape this special characters. Fortunately every json library's has way to do this job. As it seems you have used JSON.simple toolkit, you can use JSONObject.escape() method to escape the special characters.

I also faced same issue
Unexpected character (s) at position 226025.
While reading json file using code, which is mention below :
JSONParser jsonparser = new JSONParser();
try {
JSONObject jsonObj = (JSONObject)jsonparser.parse("filepath");
System.out.println((String) jsonObj.get("id"));
}
catch(Exception e) {
e.printStackTrace();
}
Then I simply updated my code using fileReader Object in my code, it worked:
JSONParser jsonparser = new JSONParser();
try {
JSONObject jsonObj = (JSONObject)jsonparser.parse(new FileReader("filepath"));
System.out.println((String) jsonObj.get("id"));
}
catch(Exception e) {
e.printStackTrace();
}

Swagger API Annotation for Java using Enum as options which break request

I have a class defined called Website Locale which lits all supported locales for my site
public enum WebsiteLocale {
AU ("au", 5, "en", "AUD"), // Australia
CA ("ca", 6, "en", "CAD"), // Canada
DE ("de", 1, "de", "EUR"), // Germany
ES ("es", 1, "es", "EUR"), // Spain
ES_US ("es-us", 2, "es", "USD"), // USA, Spanish language
EU ("eu", 4, "en", "EUR"), // Europe: English and Euros
FR ("fr", 1, "fr", "EUR"), // France
FR_US ("fr-us", 2, "fr", "USD"), // USA, French language
IT ("it", 1, "it", "EUR"), // Italy
NL ("nl", 3, "en", "EUR"), // Netherlands
UK ("uk", 1, "en", "GBP"), // UK
US ("us", 2, "en", "USD"); // USA
... getters / setters... }
In my API resource I have the following annotation
#GET
#Path("/countries")
#ApiOperation("Get countries")
#CacheControl(maxAge = 1, maxAgeUnit = TimeUnit.HOURS)
#Override
public List<CountryDto> getCountries(
#QueryParam("websiteLocale") #ApiParam(required = true, defaultValue = "uk") final WebsiteLocale websiteLocale) {
return delegate.getCountries(websiteLocale);
In the Swagger API test page for that endpoint it gives the accepted values as the Enum literals themselves
e.g. AU, CA, DE, ES, ES_US, EU, FR, FR_US
This breaks the controller (404 not found response) because it is looking for the associated string key for that enum
i.e. au, ca, de, es, es-us, eu, fr, fr-us
I had a look through swagger but could not see any specific annotation to look for a part of the enum properties.
Any ideas?
Thanks

java creating blank spaces with printf

When I run my program, I get this:
run:
Heat Index: Key West, Florida
Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
____________________________________________________________________________________________________________________________________
Temperature: 70.3 70.8 73.8 77.0 80.7 83.4 84.5 84.4 83.4 80.2 76.3 72.0
Humidity: 69.0 67.0 66.0 64.0 66.0 69.0 67.0 67.0 70.0 69.0 69.0 70.0BUILD SUCCESSFUL (total time: 0 seconds)
I want to display this so that the months align with each column of numbers, like Jan aligns with the first column of numbers and so on. I know that there are 7 blank spaces between each column of number if the months are aligned. The thing is, I don't know how to create blank spaces, like blank spaces so the months won't show up on top of the Temperature: heading, with printf. Any help will be greatly appreciated.

You need to use System.out.printf() and passing the appropriate flags for the width, see here for the syntax for formatting.
String[] months =
{"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug",
"Sep", "Oct", "Nov", "Dec"};
Double[] temper =
{70.3, 70.8, 73.8, 77.0, 80.7, 83.4, 84.5, 84.4, 83.4, 80.2, 76.3, 72.0};
Double[] humid =
{69.0, 67.0, 66.0, 64.0, 66.0, 69.0, 67.0, 67.0, 70.0, 69.0, 69.0, 70.0};
System.out.printf(" %7s%7s%7s%7s%7s%7s%7s%7s%7s%7s%7s%7s\n",
(Object[])months);
System.out.printf("________________________________________"
+ "________________________________________________________\n");
System.out.printf("Temperature:%7.1f%7.1f%7.1f%7.1f%7.1f"
+ "%7.1f%7.1f%7.1f%7.1f%7.1f%7.1f%7.1f\n",
(Object[])temper);
System.out.printf(" Humidity:%7.1f%7.1f%7.1f%7.1f%7.1f"
+ "%7.1f%7.1f%7.1f%7.1f%7.1f%7.1f%7.1f\n",
(Object[])humid);

try this.. you can specify spaces between each print..
String[] day = {"Sun", "Mon", "Tues", "Friday","Saturday"};
for(String s :day){
System.out.printf("%15s", s);
}

This will print exactly four spaces plus the three taken up by the month. Also, if you just want to print Strings you don't really need printf. Below are two options.
System.out.printf(" %s", month);
or
System.out.print(" " + month);
I would also recommend coming up with a way to do this without hard coding the spaces. Maybe set up a loop to print spaces which can change the width.

try this
System.out.println("\n");
