[ad_1] 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 [ad_2] solved Java: Delete a file starting with “.” [duplicate]
[ad_1] 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 [ad_2] solved Need java equivalent of this c# code [duplicate]
[ad_1] 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 … Read more
[ad_1] 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 [ad_2] solved Usage of Thread.currentThread().getContextClassLoader().getResourceAsStream(“system.properties”) [closed]
[ad_1] 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 [ad_2] solved Making filename remain from path in boost [closed]

[ad_1] 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 … Read more
[ad_1] 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: … Read more
[ad_1] 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 … Read more
[ad_1] 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 [ad_2] solved C# Readint a … Read more
[ad_1] 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]); … Read more
[ad_1] 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, … Read more
[ad_1] 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” … Read more
[ad_1] 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 … Read more
[ad_1] 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 more
