[ad_1] First of all please specify what do you use to draw. Do you use any API or Core-Graphics Framework for drawing. Here are some of the approaches from the link I found. Approach: on touchesEnded, save the image to app sandbox with a name like.. 1.png, 2.png etc. then put a count on “undo” … Read more
[ad_1] Many thanks for all. I used this code: count = 3 urls = {} def test(count): a = 1 while a <= count: urls[a] = ‘test’ a += 1 test(count) print(urls) [ad_2] solved Python3 – create global variable(list) from function
[ad_1] Assuming you have the corresponding getters and setters, you may try something like below: List<Person> unique = persons.stream() .collect(Collectors.groupingBy(Person::getCustomerNumber)) //returns a Map<String,List<Person>> with customerNumber as key .values() .stream() // stream and sort each list .map(e-> e.stream().sorted( Comparator.comparing(Person::getBirthday) .thenComparing(Person::getBirthTime)) .findFirst().get()) // map to first Person obj .collect(Collectors.toList()); unique.forEach(System.out::println); 1 [ad_2] solved Remove objects from list … Read more
[ad_1] pos += 1 will increment the variable pos by 1, and return it. pos = +1 is the same as saying pos = 1. The plus is redundant. See it in action with this simple script: pos1 = 10; pos2 = 10; pos1 += 1; pos2 =+ 1; console.log(‘pos1’, pos1); console.log(‘pos2’, pos2); 1 [ad_2] … Read more
[ad_1] String year1= String.valueOf (year); String month1= String.valueOf(month); String day1= String.valueOf(day); must be changed to String year1= String.valueOf (num1); String month1= String.valueOf(num2); String day1= String.valueOf(num3); because these 3 variables only hold the values entered by the user. Also, not sure why you need the hour, because you never get that as inout from the user. … Read more
[ad_1] It’s because of your “currentStateOpened”. If you addd your first Item it will be set to false and thus the second item will have as total price “0”. However, you probably should code the whole thing differently. I hope that is for training purposes to get started with JS and you don’t plan on … Read more
[ad_1] Even though this is a very specific problem, here’s a solution: var array1 = new[] { 2, 5, 7, 8, 9, 4 }; var array2 = new [] { 4, 8, 2, 1, 5, 8 }; array1 = array1.Select((i, index) => i % 2 == 1 ? array2[index] : i).ToArray(); //result: int[6] { 2, … Read more
[ad_1] You can do something like, NSString *str = @”any string”; NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding]; NSMutableData *mutableData = [data mutableCopy];; Hope this will help 🙂 0 [ad_2] solved Convert string to mutable data – objective c [duplicate]
[ad_1] Time Delay float delay = 1; // seconds Timer.schedule(new Task(){ @Override public void run() { // Do your work } }, delay); The above code helps you delay the execution, and after that delay you can perform the action you want. Here, Inside the run method you can switch to any screen and ofcourse … Read more
[ad_1] You are passing the arrays to sameNumberCheckOfTwoArrays as pointers. In this process, the “array-ness” is dropped. Your function only sees an int* and reports the size accordingly. 3 [ad_2] solved Something went wrong with passing pointer to a function
[ad_1] Try something along the lines of this… $(document).ready(function() { var url = window.location.href; var UrlofpageX = url.indexOf(‘theurlyouwanttolookfor’); if (UrlofpageX >= 0) { $(‘.yourlink’).append(‘<a href=”https://website-B”><li>Your different link</li></a>’); } else { $(‘.yourlink’).append(‘<a href=”https://website-A”><li>Your original link</li></a>’); } }); So what happens here is you get the URL of the page that you’re currently on. It gets stored … Read more
[ad_1] you forgot that counting starts at 0 so its 0-99 and not 1-100. The 100th element is at string.printable[99] EDIT: assuming you want to loop around, you should use the modulus operator % so to access the 100th item in a 100 item list you would do: string.printable[99%100] to get the 180th item in … Read more
[ad_1] Join var x = [1,2,3].join(“”); console.log(typeof x); console.log(x) Split var text = “1,2,3”; var array = text.split(“,”); console.log(array); [ad_2] solved How to convert an array into a string in javascript without the use of ‘string()’ function? [closed]
[ad_1] The conditional operator is intended to be used with assignments, not as a generalized replacement for the if/else statements. This is because it produces a result (it is an expression), and that result is then assigned to something else. For example, consider the following statement: var a = x != null ? x : … Read more
[ad_1] Try using this code instead of the way you are going : public String performPostCall(String requestURL, HashMap<String, String> postDataParams) { URL url; String response = “”; try { url = new URL(requestURL); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setReadTimeout(15000); conn.setConnectTimeout(15000); conn.setRequestMethod(“POST”); conn.setDoInput(true); conn.setDoOutput(true); OutputStream os = conn.getOutputStream(); BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, “UTF-8”)); writer.write(getPostDataString(postDataParams)); … Read more
