public static void main(String[] args) { Scanner numPlayers = new Scanner(System.in); ArrayList<Player> playerList = new ArrayList<>(); int input = numPlayers.nextInt(); for (int i = 0; i < input; i++){ System.out.println(“what is player ” + (i + 1) + ” name?”); String playerName = numPlayers.next(); playerList.add(new Player(playerName)); } } You should have declared scanner object outside … Read more
I suggest you a simple way cause you are new in android! add this function to your listView adapter: public void filterList(String searchText) { ArrayList<C_ChatListItem> temp = new ArrayList<>(); adapteritems = backupItems; // copy your Get response in backupItems for new searches in constructor // then in every new search retrieve adapterIems if(searchText != null … Read more
Your code was mostly correct: You had some typos that would prevent your code compiling successfully. You should consider using an IDE such as Eclipse, as it will highlight these kinds of issues for you as you type. You shouldn’t create a 2nd Scanner object, reuse the existing one Be sure to close your Scanner … Read more
if the project is maven please update the following dependency <dependency> <groupId>com.microsoft.sqlserver</groupId> <artifactId>mssql-jdbc</artifactId> <version>8.2.1.jre11</version> </dependency> 1 solved I have every problem like this. does anyone know how to fix it? thank you [closed]
This the Kotlin code which does what you want (it was easier for me to develop it this way): import java.util.* fun main(args: Array<String>) { val input = Scanner(System.`in`) print(“Please enter a number range: “) val numOfCols = input.nextInt() print(“Please enter a number of rows: “) val numOfRows = input.nextInt() for (i in 1..numOfRows) { … Read more
Use isRange(mMyLatitude, mMyLongitude, mPoi.getPoiLatitude(), mPoi.getPoiLongitude) instead of isRange(MyLatitude, MyLongitude, MpoiLatitude, MpoiLongitude) FYI, its better to use small letter for naming variable. 2 solved Cannot resolve symbol myLatitude
This is really confusing but you are missing something basic here. equals() is just a method, and you test its return value just like any other method. In this case, it returns a boolean, which is what the if statement wants, hence there is no need for testing == to some value. public class MyTest … Read more
The ratings json should be formatted as an array. In json, array of values would be declared like this: { “title”:”Numb”, “artist”:”Linkin Park”, “ratings”:[5,4,5,1,3], “youtubeID”:”kXYiU_JCYtU” } In your case, there was a confusion whether 4 was the next element of the ratings array or if it was the next element in json. And before parsing … Read more
No, it is not good. It is considered a good practice to have an adapter as a stand-alone class (not nested one) as it will give you the benefit of code reuse. Also, if you decide that you need a nested class anyway, make it private. I recommend a book from Head First series: Android … Read more
So this is my solution, there are better ways you can use backtracking to generate sudoku, like just calling fuelleArray(fieldIndex, numberInField). With that, backtracking would be more visible and clear in the code and you won’t have to deal, like I had, with the cases when its on the end of a row. public static … Read more
I would probably consider doing this another way… Have an empty hashmap<String sub, int multiplier> Read in the name Generate the subname Fetch from or create subname in hashmap If new, set multiplier to 1 If exists, increment multiplier Return String.format(“%s%3d”, subname, multiplier x 5).toUpperCase() I would give you code but writing the above was … Read more
It may be a problem with scope (what’s declared inside the brackets may not be available after the brackets close). Not sure what Java is doing. if (totalSeconds >= 60) { int intMinutesFromSeconds = (int) minutesFromSeconds; } int totalMinutes = intMinutesFromSeconds + … You can fix it with something like: int intMinutesFromSeconds = 0; if … Read more
Try this: Open CMD: 1. sqlplus / as sysdba; 2. create user test identified by 123; 3. grant all privileges to test; Here: test is the new user whose password is 123 Now when you need to login with this user Type in CMD: Sqlplus test/123 Correction: In URL: url=”jdbc:oracle:thin:@localhost:1523:system”; the last parameter should be … Read more
You should use == to copmare not use = and ; after if statment not correct. You can see the code after edit like this: import java.util.Scanner; class Test{ public static void main(String args[]){ Scanner sc=new Scanner(System.in); System.out.println(“Pick option:\n 1-Option one\n 2-Option two :”); int x= sc.nextInt(); if (x==1) { System.out.println(“You select option one”); } … Read more
Try this following code. for(int i=0;i<route.length();i++) { JSONObject routeObject = route.getJSONObject(i); TrainStatus trainStatus = new TrainStatus(); JSONObject jsonObject_station = routeObject.getJSONObject(“station”); String stationname = jsonObject_station.getString(“name”); String code = jsonObject_station.getString(“code”); Log.d(“checkvalue”, ” ” + stationname + ” ” + code); trainStatus.setSerialNo(routeObject.getInt(“no”)); trainStatus.setScheduleArrival(routeObject.getString(“scharr”)); trainStatus.setActualArrival(routeObject.getString(“actarr”)); trainStatus.setStatusOfArrival(routeObject.getString(“status”)); trainStatus.setHasArrived(routeObject.getBoolean(“has_arrived”)); trainStatus.setHasDeparted(routeObject.getBoolean(“has_departed”)); trainStatus.setLatemin(routeObject.getInt(“latemin”)); trainStatus.setActualArrivalDate(routeObject.getString(“actarr_date”)); trainStatus.setScheduleArrivalDate(routeObject.getString(“scharr_date”)); trainList.add(trainStatus); } 6 solved Parse JSON to fetch … Read more
