Use the nio package instead : import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; Path p = Paths.get(“/tmp/.minecraft”); if(!Files.exists(p)){ Files.createFile(p); } if(Files.exists(p)){ Files.delete(p); } 10 solved Java: Delete a file starting with “.” [duplicate]
You can do the same with Streams: Map<String, String> dic = Files.lines(Paths.get(AlphabetFile)) .map(l -> l.split(“=”)) .collect(Collectors.toMap(s -> s[0].trim(), s -> s[1].trim())); 1 solved Need java equivalent of this c# code [duplicate]
Does any other language support this? C++ supports it. You can seek and you can write. But the fact that this is a very uncommon scenario to replace the same exact byte length and the fact that replacing a bunch of bytes with another bunch of bytes that has a different length is horribly inefficient … Read more
It simply means: Return the property file as InputStream from the ClassLoader the current thread of my application is running from (in loose english). 4 solved Usage of Thread.currentThread().getContextClassLoader().getResourceAsStream(“system.properties”) [closed]
You don’t need Boost: std::string str = “data/lib/blahblah.lua”; std::string filename(str, str.find_last_of(“https://stackoverflow.com/”)+1); 0 solved Making filename remain from path in boost [closed]

Can be extracted with a simple regular expression, as long as the text file is in the same format as the Python log output you posted (Returns all of them): import re file=””.join([i for i in open(“yourfileinthesamefolder.txt”)]) serials=re.findall(“u’serial_number’: u'(.+)'”,file) print(serials) I suggest reading up on how to use regular expressions in Python: Regular Expression HOWTO … Read more
I would reccomend using with (docs) whenever you do file I/O in python. Also, iterate over each line instead of using inFile.read(). If you have a large file, your machines memory will thank you. def stats(inF): num_lines = 0 num_words = 0 num_chars = 0 with open(inF, ‘r’) as input_file: for line in input_file: num_lines … Read more
Try read.csv() dat <- read.csv(text = “Control,3 Test,3 Control,3 Control,3 Test,1 Control,3 Control,1”, header = FALSE) > dat V1 V2 1 Control 3 2 Test 3 3 Control 3 4 Control 3 5 Test 1 6 Control 3 7 Control 1 However, you’ll need read.csv(file = “foo.csv”, header = FALSE) and replace foo.csv with the … Read more
To acomplish your goal you need to do two steps: Read the entire file. Transform to appropiate structure. Thanks to LINQ you can accomplish quickly: var cells = (from l in System.IO.File.ReadAllLines(“myfile.txt”) select l.Split(” “.ToArray(), StringSplitOptions.RemoveEmptyEntries)).ToArray(); Now you can access the cells like this: var value = cells[1][2]; 3 solved C# Readint a txt file … Read more
The array is better declared and allocated like this: char **lineArray;. lineArray = (char **)malloc(sizeof(char *) * (lineCount-1)); strtok take a string as second argument. Replace const char j=’ ‘; by const char *j=” “; Get rid of the first strtok: lineArray[p]=malloc(strlen(line));//1st bunch of memory allocated strcpy(lineArray[p],line); printf(“%s\n”,lineArray[p]); //token = strtok(lineArray[p],j); //printf(“%s\n”,token); //serialno[p]=atoi(token); //printf(“%d\n”,serialno[p]); x=1; … Read more
In general you don’t want to modify the contents of files directly (in-place) unless the data is formatted in fixed structures. The most common approach would be to rename the existing file, opening it to read, and opening a new file by the same name for write access. Then stream through the input data, performing … Read more
It doesn’t make any sense to generate text files and then folders to move the files to. Create the folders first place and create the files into the folders. Using a (code block) only one for loop is needed. @echo off setlocal for /f “tokens=*” %%a in (comps.txt) do ( if not exist “%%a” mkdir … Read more
StreamReader smsmessage = new StreamReader(filePath); try { FileInfo filenameinfo = new FileInfo(filePath); …. smsmessage = filenameinfo.OpenText(); … You are initializing smsmessage twice, but only disposing one of those instances. The first line constructs a StreamReader, and then you overwrite your reference to that instance with the instance created by filenameinfo.OpenText(). That leaves you with an … Read more
Using feof() is a bad idea as it can return zero, and then the next line of input can encounter end of the file – which can give unexpected errors Also fgets() returns NULL if an error occurs, including encountering end of file. Imagine your loop has been going along happily, and has just read … Read more
