How to validate array item types with networknt/json-schema-validator?

its probably a very simple thing that Im missing, but my json-schema-validator (networknt/json-schema-validator) doesnt validate the type of my items inside an array.
This Java-snippet should yield errors:
var schema = "{\n" +
" \"$schema\": \"http://json-schema.org/draft/2020-12/schema#\",\n" +
" \"type\": \"array\",\n" +
" \"items\": [\n" +
" {\n" +
" \"type\": \"integer\"\n" +
" }\n" +
" ]\n" +
"}";
var input = "[true,false,{},\"foo\"]";
var factory = JsonSchemaFactory.getInstance(SpecVersion.VersionFlag.V202012);
var jSchema = factory.getSchema(schema);
var errors = jSchema.validate(new ObjectMapper().readTree(input));
System.out.println("Errors: '"+errors.stream().map(ValidationMessage::getMessage).collect(joining(", ")) +"'");
but 'errors is empty. Over on www.jsonschemavalidator.net this is invalid as expected.
What obvious am I overlooking here ?
Thanks!

avoid adding the same element if exist in the list instead just add the elements inside the existing list [duplicate]

This question already has an answer here:
Add item to arraylist if it does not already exist in list

for(int i = 0; i<myData.size();i++)
{
String type = "SIT";
FeaturedItems item = resultList.stream().filter(featureItem -> type != null && type.equals(featureItem.getType())).findFirst().orElse(null);
if (type != null) {
item = FeaturedItems.builder().type(type).items(new ArrayList<>()).build();
resultList.add(item);//if the item already exists in the list don't add the new item, instead just add the elements in the exisiting item.
//tried the below commented code to add the item if it doesn't contain in the list -- start
/*boolean flagFound = false;
for (FeaturedItems featureItem : resultList) {
if (featureItem.getType().equalsIgnoreCase(type)) {
flagFound = true;
break;
}
}
if(!flagFound) resultList.add(item);*/

for (int count = 0; count < features.size(); count++) {
String id = getFid(count);
MyDataBuild build = ....//logic to set values in the properties
item.getItems().add(build);
}
}
}
lookUpData.setFeatureGroups(resultList);
}
}
If the type value is already defined in the defined featureItems, then instead of creating the new object in the featureItems list, i need to add the unique items(desc,id) to the existing items element for the matching type. The code snippet mentioned above doesn't add the elements to the existing items if the type is matching in the featureItems list, instead it is creating the new element as shown in the output json sample.

Using a Map instead will make your live much easier. However your example is missing some data so it's a bit hard to understand what is actually happening in your code. So I can give you only a simple example for the usage.
Map<String, FeaturedItems> resultMap = new HashMap<>();
// Get the FeaturedItems for the given type. If none is present create a new one.
FeaturedItems items = resultMap.computeIfAbsent(type, k -> FeaturedItems.builder().type(k).items(new ArrayList<>()).build());
// Add your item to the list
Sale newItem // Obtain new item
items.getItems().add(newItem);

I don’t really understand how the Java Regex Pattern works. I tried to find this URL many times but I'm failed.
I would be grateful if someone will help with that or at least give me a link guide of java regex for a newbie. thx

It seems to me you are trying to extract URLs from JS code using java.
There are many regex playgrounds on the web you can try such as:
http://buildregex.com
https://regex101.com
and of course Google
Search.
For your specific case :
import java.util.*;
import java.util.regex.*;
import java.net.*;
public class HelloWorld{
public static void main(String []args){
System.out.println("Hello World");
String jsCode ="<script>function getcookie(Name){\n" +
" var search=Name+\"=\";\n" +
" if(document.cookie.length>0){\n" +
" offset=document.cookie.indexOf(search)\n" +
" if(offset!=-1){\n" +
" offset+=search.length\n" +
" end=document.cookie.indexOf(\";\",offset)\n" +
" if(end==-1){end=document.cookie.length}\n" +
" return unescape(document.cookie.substring(offset, en))\n" +
" }\n" +
" }\n" +
"}\n" +
" var player = new Playerjs({\n" +

" function PlayerjsEvents(event,id,data){\n" +
" if(event==\"start\"){\n" +
" var xhttp = new XMLHttpRequest();\n" +
" xhttp.open(\"GET\", \"stat.php?id=2147414277\", true);\n" +

List<String> urls = new ArrayList<String>();
String myUrlPattern = "((https?|file):((//)|(\\\\))+[\\w\\d:##%/;$()~_?\\+-=\\\\\\.&]*)";
Pattern p = Pattern.compile(myUrlPattern);
Matcher m = p.matcher(jsCode);
while (m.find()) {
urls.add(m.group());
}
for(String s: urls)
System.out.println(s);
}
}
Gives out:

How to drag & drop in specific position in selenium java?

I am trying to drag & drop 2 elements into my workspace but they are dropped over each other, how can i specify the position of dropping the elements?
I am using dragAndDrop() function
Actions act=new Actions(driver);
act.dragAndDrop(From, To).build().perform();
enter image description here

Using dragAndDrop() method you can perform drag and drop operations on only one location at a time. it is usually used to perform operations on web element which is capable of dropping. please find the reference http://demoqa.com/droppable/ for various types of dropable elements.
To implement drag and drop operation -
Example:
WebElement From=driver.findElement(By.xpath( <<source xpath>> ));
WebElement To=driver.findElement(By.xpath( <<destination xpath>> ));
Actions actions=new Actions(driver);
actions.dragAndDrop(From, To).build().perform();
to drag and drop another element, you need to perform above all steps again.
Hope this helps :)

Try Using below code :
public static void dragAndDropViaJQueryHelper(WebDriver driver, String dragSourceJQuerySelector, String dropTargetJQuerySelector) {
String jqueryScript = "(function( jquery ) {\r\n" +
" jquery.fn.simulateDragDrop = function(options) {\r\n" +
" return this.each(function() {\r\n" +
" new jquery.simulateDragDrop(this, options);\r\n" +
" });\r\n" +
" };\r\n" +
" jquery.simulateDragDrop = function(elem, options) {\r\n" +
" this.options = options;\r\n" +
" this.simulateEvent(elem, options);\r\n" +
" };\r\n" +
" jquery.extend(jquery.simulateDragDrop.prototype, {\r\n" +
" simulateEvent: function(elem, options) {\r\n" +
" /*Simulating drag start*/\r\n" +
" var type = 'dragstart';\r\n" +
" var event = this.createEvent(type);\r\n" +
" this.dispatchEvent(elem, type, event);\r\n" +
"\r\n" +
" /*Simulating drop*/\r\n" +
" type = 'drop';\r\n" +
" var dropEvent = this.createEvent(type, {});\r\n" +
" dropEvent.dataTransfer = event.dataTransfer;\r\n" +
" this.dispatchEvent(jquery(options.dropTarget)[0], type, dropEvent);\r\n" +
"\r\n" +
" /*Simulating drag end*/\r\n" +
" type = 'dragend';\r\n" +
" var dragEndEvent = this.createEvent(type, {});\r\n" +
" dragEndEvent.dataTransfer = event.dataTransfer;\r\n" +
" this.dispatchEvent(elem, type, dragEndEvent);\r\n" +
" },\r\n" +
" createEvent: function(type) {\r\n" +
" var event = document.createEvent(\"CustomEvent\");\r\n" +
" event.initCustomEvent(type, true, true, null);\r\n" +
" event.dataTransfer = {\r\n" +
" data: {\r\n" +
" },\r\n" +
" setData: function(type, val){\r\n" +
" this.data[type] = val;\r\n" +
" },\r\n" +
" getData: function(type){\r\n" +
" return this.data[type];\r\n" +
" }\r\n" +
" };\r\n" +
" return event;\r\n" +
" },\r\n" +
" dispatchEvent: function(elem, type, event) {\r\n" +
" if(elem.dispatchEvent) {\r\n" +
" elem.dispatchEvent(event);\r\n" +
" }else if( elem.fireEvent ) {\r\n" +
" elem.fireEvent(\"on\"+type, event);\r\n" +
" }\r\n" +
" }\r\n" +
" });\r\n" +
"})(jQuery);";
((JavascriptExecutor) driver).executeScript(jqueryScript);
String dragAndDropScript = "jQuery('" + dragSourceJQuerySelector + "').simulateDragDrop({ dropTarget: '" + dropTargetJQuerySelector + "'});";
((JavascriptExecutor) driver).executeScript(dragAndDropScript);
}
Just pass css or xpath selectors in parameters.
Hope that helps you.
If that does not help you I can help you out with some other solutions also.

sqlite JOIN query for multiple entries

My database has "diary" table and "food" table. In diary table I have following columns: date, food1,food2, ...food10. In food table I have: id, name, allergen1, allergen2, allergen3. So basically you log up to 10 foods a day to diary. Now I'm trying to build a query which would let me find last date that I've eaten food with allergen3. So that's the query I came up with, which you probably know is not working ;-)
Cursor findDateRes = db.rawQuery("SELECT date(" + DIARY_COL_DATE + ") FROM " + DIARY_TABLE
+ " INNER JOIN " + FOOD_TABLE + " food1 ON (food1." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F1 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food2 ON (food2." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F2 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food3 ON (food3." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F3 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food4 ON (food4." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F4 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food5 ON (food5." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F5 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food6 ON (food6." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F6 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food7 ON (food7." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F7 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food8 ON (food8." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F8 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food9 ON (food9." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F9 + ")"
+ " INNER JOIN " + FOOD_TABLE + " food10 ON (food10." + FOOD_COL_1 + " = " + DIARY_TABLE + "." + DIARY_COL_F10 +
") WHERE 1 NOT IN (food1." + FOOD_COL_5 +
",food2." + FOOD_COL_5 +
",food3." + FOOD_COL_5 +
",food4." + FOOD_COL_5 +
",food5." + FOOD_COL_5 +
",food6." + FOOD_COL_5 +
",food7." + FOOD_COL_5 +
",food8." + FOOD_COL_5 +
",food9." + FOOD_COL_5 +
",food10." + FOOD_COL_5 +
") ORDER BY date(" + DIARY_COL_DATE + ") ASC LIMIT 1", null);
"FOOD_COL_1" stands for id and "FOOD_COL_5" stands fro allergen3.
Thank you for looking. Any input will be appreciated.
