You can do it using nested loop, as you said in the question: public String[] randomArrayString(int length, int numberOfChar) { Random random = new Random(); char[] chars = “abcdefghijklmnopqrstuvwxyz”.toCharArray(); String[] array = new String[length]; String str; for (int i = 0; i < length; i++) { str = “”; for (int j = 0; j … Read more
Welcome to SO. You are using a function, findObjectsInBackground, that takes a completion closure. The completion closure is another function inside your cellForRowAt function. That function holds onto (captures) the completion closure you pass in and doesn’t call it until the background call is complete. The block you pass in does not return a value. … Read more
Does the following help: var currentMode = 1; var discount = 0.20; var reverseDiscount = 1/(1-discount); function togglePrices() { var prices = document.getElementsByClassName(“price”); for (var i = 0; i < prices.length; i++) { var individualPrice = prices[i].innerHTML.substring(1); if(currentMode == 1) { individualPrice = parseFloat(individualPrice) * (1-discount); } else { individualPrice = parseFloat(individualPrice) * reverseDiscount; } … Read more
You would probably use cURL from php. cURL can do so many things, so you can probably google “php curl upload” or something the get more specific answers. But the key-word you are looking for is probably cURL. Please note that if you are going server-to-server, CORS will not make any difference — CORS only … Read more
This is my solution I state in the comment, as you can see is a nest of LinearLayouts <?xml version=”1.0″ encoding=”utf-8″?> <LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:tools=”http://schemas.android.com/tools” android:id=”@+id/activity_main” android:layout_width=”match_parent” android:layout_height=”match_parent” android:weightSum=”100″ android:paddingBottom=”@dimen/activity_vertical_margin” android:paddingLeft=”@dimen/activity_horizontal_margin” android:paddingRight=”@dimen/activity_horizontal_margin” android:paddingTop=”@dimen/activity_vertical_margin” android:orientation=”vertical” tools:context=”net.whatsgift.mitro.weightlayout.MainActivity”> <LinearLayout android:layout_width=”match_parent” android:layout_height=”match_parent” android:layout_weight=”50″ android:orientation=”horizontal” android:weightSum=”100″> <LinearLayout android:layout_width=”match_parent” android:layout_height=”match_parent” android:layout_weight=”50″ android:backgroundTint=”@color/colorAccent”></LinearLayout> <LinearLayout android:layout_width=”match_parent” android:layout_height=”match_parent” android:layout_weight=”50″ android:backgroundTint=”@color/colorPrimary”></LinearLayout> </LinearLayout> <LinearLayout android:layout_width=”match_parent” android:layout_height=”match_parent” android:layout_weight=”50″ … Read more
You can use the or operator to assign a “default value” to a variable. This works because a or b is equivalent to a if a else b. Thus you could write lista = GETLISTA() or some_default Notice, however, that this will also use some_default if GETLISTA() evaluates to an empty list [], or any … Read more
In C#, what does a call to Sort with two parameters in brackets mean? You have this line of code: nodes.Sort((x, y) => distances[x] – distances[y]); You are not passing two parameters to the sort method but you are passing one parameter which is a delegate that takes 2 parameters. You are essentially doing the … Read more
private ArrayList<Student> readFile() throws FileNotFoundException { String fName = “p02-students.txt”; Scanner scan = new Scanner(new File(fName)); ArrayList<Student> studentList = new ArrayList<Student>(); while (scan.hasNext()) { String studentType = scan.next(); if (studentType.equals(“C”)) { studentList.add(readOnCampusStudent(scan)); } else { studentList.add(readOnlineStudent(scan)); } scan.nextLine(); } scan.close(); return studentList; } I didn’t get the error you mentioned earlier, but I was getting … Read more
When I understood the problem right then you can hold the last start number in a local variable: private int lastStartNumber = 0; private int getNextStartNumber(){ lastStartNumber = lastStartNumber + 1; return lastStartNumber; } 0 solved Give every new object a new attribute value (participants and start numbers)
Try this: .input_with_icon { position: relative; } .input_with_icon .form-control { padding-left: 40px; height: 21px; } .input_with_icon img { position: absolute; top: 5px; bottom: 0; left: 10px; margin: auto; } <div class=”input_with_icon”> <input type=”text” class=”form-control” placeholder=”Search here…”> <img src=”https://stackoverflow.com/questions/59323509/images/search.png”> </div> solved Making an input icon (search icon) responsive [closed]
Since I cannot find any pattern on the given criteria for the value of b, I suggest addressing this problem using ranges (although it is tiring). The criteria, however, fail if a > 10,000. In order to address this, I’ve added a simple “catch” of alerting the user of incorrect input, and not to continue … Read more
First for future reference you should probably post that on code review, unless there is a specific problem then you should create a Minimal, Complete, and Verifiable post. There is nothing inherently wrong other than you do not check that N>0 which could lead to an infinite loop, j should be going to i not … Read more
This is one way (it does create two streams and does merge the two lines of code): Map<String, Long> map = Arrays.stream(“some text some spaces”.split(” “)) .collect(Collectors.groupingBy(Function.identity(), Collectors.counting())) .entrySet() .stream() .sorted(Map.Entry.<String, Long>comparingByValue().reversed()) .collect(Collectors.toMap(e -> e.getKey(), e -> e.getValue(), (v1, v2) -> v2, LinkedHashMap::new)); System.out.println(map); // This prints: {some=2, spaces=1, text=1} solved Word count in descending … Read more
It’s not so clear what you’re asking, but here are some options to get you started: Manual Min-max transform You could min-max transform so they are all in the range of [0,1], and then multiply by 255. Then, all your values are in the range of 0 to 255, proportional to your original array (i.e. … Read more
Like people have said there are many ways to do this. One way would be to use JavaScript event listeners. Here’s a quick little demo: let change = document.getElementById(“change”); let hover = document.getElementById(“hover”); hover.addEventListener(“mouseover”, changeColor); hover.addEventListener(“mouseout”, changeColor); function changeColor() { change.classList.toggle(“red”); } div { width: 100px; height: 100px; margin: 2rem; background-color: green; } .red { … Read more
