if you want values in a new array, then int[] array ={1,2,3,4,5}; int arrayLength = array.size(); int[] array2 = new int[arrayLength]; for(int i=0; i<arrayLength; i++) { array2[i] = array[i]*2; } If you want values doubles in the same array, then int[] array ={1,2,3,4,5}; for(int i=0; i<array.size(); i++) { array[i]*=2; } 0 solved If I have … Read more
Arrays are not pointers, and pointers are not arrays. The first parameter type says that list is a pointer to an array of char.cArray isn’t; it’s a pointer to char*. The second says that list is a pointer to an array of char*, which is even further from cArray. You need to pass the correct … Read more
You need to actually initialize syncModelRecord. Try this: let syncModelRecord = SyncModelRecord(date: String(Int64(syncTimestamp!)), shakeState: 0) dummySyncModelRecordArray.append(syncModelRecord!) Another tip maybe worth exploring, you can directly decode a date and specify the decoder’s strategy for it (in your case secondsSince1970) solved How to make an array using dummy values from Struct Modal class in Swift iOS

ArrayMap keeps its mappings in an array data structure — an integer array of hash codes for each item, and an Object array of the key -> value pairs. Where ArrayList is a List. Resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. FYI ArrayMap is a … Read more
The error message tells you exactly what’s wrong. There is no declared variable by the name of array. public class ArrayObjects<E> implements SomeImp<E> { int maxCapacity, actualSize; E[] array; // <- The missing declaration @SuppressWarnings(“unchecked”) // <- Suppress the “unchecked cast” warning public ArrayObjects() { maxCapacity = 10; array = (E[]) new Object[maxCapacity]; } } … Read more

Change the increment amount as you please… var arr = []; var i = 1; var incrementAmt = 2000; for(var j = 0; j < 1000; j++) { var num = i + incrementAmt; arr.push(num); i = num; i++; incrementAmt = incrementAmt / 2; // cause incrementer to decrease each iteration } console.log(arr) 1 solved … Read more
Based on Nacho’s idea, this is my solution (not ideal, but I’ll take it for now): [TestCase(new int[] { 0, 1, 2, 3 }, true)] [TestCase(new int[] { 0, 3, 4 }, false)] [TestCase(new int[] { 4, 4, 4 }, true)] [TestCase(new int[] { 6, 6, 8, 8 }, true)] [TestCase(new int[] { 5, 4, … Read more
The comparison function allows you to create custom logic to determine whether the two entries are the same or not. The keys in these two arrays look totally different, because they are in different languages. $data1 = [ ‘red’ => true, ‘yellow’ => true, ‘green’ => true, ‘blue’ => true, ‘black’ => true, ]; $data2 … Read more
In ECMAScript 6 Map type is an ordered list of key-value pairs, where both the key and the value can have any type. A Map object iterates its elements in insertion order. The forEach method executes a provided function once per each key/value pair in the Map object, in insertion order. var a = new … Read more
The function for onClick attribute in XML has to be something like, public void yourFunction (View view) { //Your code } Since you didn’t add View as the argument of your function, your layout is never going to get to it, hence when you click on your button, the app crashes. You also need to … Read more
Finally I solved this problem with the MySQL. created a column with all code. and then call the script every-time when user press button. In the script first I fetch first raw and print that value, and then, delete that raw. so every-time user will get unique value from the list of code And it … Read more
