How to use jUnit's TemporaryFolder in scala's specs2 tests?

I'm writing a test with Playframework, and I need to create a temporary file. @RunWith(classOf[JUnitRunner]) class DiagnosticSpec extends Specification { @Rule val temporaryFolder: TemporaryFolder = new TemporaryFolder() "my test" should { "run with temporary file" in { val file = temporaryFolder.newFile() // line.35 // go on with the file } } } But when I run this test, it always throw exception: [error] IllegalStateException: the temporary folder has not yet been created (MyTest.scala:35) Is it possible to use it in specs2? If not, how can I create a temporary file in specs2, and delete it

How to read a specific line in a text file in C (integers)

I'm having a problem with a program (part of a program). To proceed any further I need to somehow read a line of a file but that must be a specific line. I'm really new to C and files... What I'm trying to do, is to ask the user to enter the specific line they want to read and then display it to them. At the moment, when I try to print the text from the line it gives me text from line 1 only. Please note that by text I mean integers since the file consists of 55 integers in one column. So it looks like this: 12 18 54 16 21 64 ..... Is there any way to achieve what I need? #include <stdio.h>

Scanner Class hasNextLine infinite loop

why does this piece of code go into an infinite loop when I try to give it a basic text file? import java.io.File; import java.io.FileWriter; import java.io.IOException; import java.util.*; public class TestFile { public static void main(String args[]) throws IOException { // Read in input file File input = new File(args[0]); Scanner freader = new Scanner(input); while (freader.hasNextLine()) { System.out.println("hi"); } freader.close(); } } The print line just keeps going.

Does file() lock the file when reading?

I'm using file() to read through a file like an array with tabs. I want to lock the file but I cannot seem to get flock() working on the file. Is it possible to do this? If so, how? If not, does the file() lock the file from the start and alleviate any potential sharing problems?

Reading formatted file into char array in C

I have a very simple problem. I need to read in the contents of a file into a char array in C. The file will always be formatted as two columns of letters, e.g.: A B B C E X C D Each letter represents a vertex on a graph, which I'll be dealing with later. I've learned programming using C++ and Java, but I'm not extraordinarily familiar with C specifically. What's causing the problem that I can't figure out is the fact that the file is multiple lines long. I need each letter to occupy a slot in the array, so in this case it'd be: array[0] = 'A', array[1] = 'B', array[2] = 'B', array[3] = 'C'

Laravel file download - php_fileinfo extension not enabled

I'm using Laravel 5.4.13 with PHP 7.1 and I migrated to a shared hosting. I'm trying to make the website work, but I'm unable because of a missing extension: php_fileinfo This is the code where the website crashes: $file = base_path() .
