I'm trying to read every file in a directory, clean up with java util.locale, then write to a new directory. The reading and writing methods work, the Locale.SPANISH might be the issue as I have read in other posts.
I iterated through the available languages in the java.util.locale, spanish was in there.
First, the array issue: the following extract of code below is the long way of entering the Locale.(LANGUAGE) into the array. This seems to work fine. However, I can't understand why the 'short' way doesn't seem to work.
String[] languageLocale = new String[fileArray.length];
languageLocale[0] = "Locale.ENGLISH";
languageLocale[1] = "Locale.FRENCH";
languageLocale[2] = "Locale.GERMAN";
languageLocale[3] = "Locale.ITALIAN";
languageLocale[4] = "Locale.SPANISH";
The short way:
String[] languageLocale = new String[("Locale.ENGLISH" , "Locale.FRENCH" , "Locale.GERMAN" , "Locale.ITALIAN" , "Locale.SPANISH")];
I need to input the Locale.(langauge) into a string so they can be called in the following:
File file = new File("\\LanguageGuessing5.0\\Learning\\");
File[] fileArray = file.listFiles();
ArrayList<String> words = new ArrayList<String>();
for (int i = 0; i < fileArray.length; i++) {
if (fileArray[i].isFile()) {
if (fileArray[i].isHidden()) {
continue;
} else {
String content = readUTF8File("\\LanguageGuessing5.0\\Learning\\"+fileArray[i].getName());
words = extractWords(content, languageLocale[i]);
outputWordsToUTF8File("\\LanguageGuessing5.0\\Model\\"+ fileArray[i].getName() + "out.txt", words);
}
} else if (fileArray[i].isDirectory()) {
System.out.println("Directory " + fileArray[i].getName());
}
}
The following method call:
words = extractWords(content, languageLocale[i]);
also presents the following error:
The method extractWords(String, Locale) in the type CleaningText(the class name) is not applicable for the arguments (String, String)
My understanding is that while the array argument is not a locale, the string holds the correct text to make it valid. I'm clearly incorrect, I'm hoping someone could explain how this works.
The input types of the methods are below for context:
public static String readUTF8File(String filePath)
public static ArrayList extractWords(String inputText, Locale currentLocale)
public static void outputWordsToUTF8File(String filePath, ArrayList wordList)
Many thanks in advance

Below is the concerned code. Basically what the code is supposed to do is output the URL, name and version of each GitHub release defined by GetUpdateInfo.getInfo().
GetUpdateInfo.getInfo (NOTE Strings login, oauth and password omitted for security reasons.):
import java.util.List;
import org.kohsuke.github.*;
import org.apache.commons.lang3.ArrayUtils;
public class GetUpdateInfo {
public static getInfo() {
String version = "";
String url = "";
String[] urls = {};
String[] names = {};
String[] versions = {};
String[] releases = {};
GitHub github = GitHubBuilder.fromEnvironment(login, password, oauth).build();
//Get the repo name from the organization
GHOrganization gho = github.getOrganization("NuovoLauncher-Mods");
PagedIterable<GHRepository> repos = gho.listRepositories();
List<GHRepository> repos_list = repos.asList();
for(int i=0; i < repos_list.size(); i++) {
GHRepository repo_test = repos_list.get(i);
GHRelease latest = repo_test.getLatestRelease();
ArrayUtils.add(releases, latest.toString());
ArrayUtils.add(names, latest.getName());
ui.setName(names);
ui.setRelease(releases);
List<GHAsset> assets = latest.getAssets();
for( int x = 0; x < assets.size(); x++ ) {
GHAsset asset = assets.get(x);
url = asset.getBrowserDownloadUrl();
version = url.split("/")[7];
System.out.format("URL: %s, Name: %s, Latest Release: %s. Version %s\n", url, latest.getName(), latest, version);
ArrayUtils.add(urls, url);
ArrayUtils.add(versions, version);
ui.setURL(urls);
ui.setVersion(versions);
}
}
return ui;
}
public static void main(String[] args) throws Exception {
GetUpdateInfo.getInfo();
}
}
DownloadUpdate.runner:
public static void runner() throws Exception {
String system_type = System.getProperty("os.name");
File fpath = new File("");
UpdateInfo ui = GetUpdateInfo.getInfo();
for(int i = 0; i < ui.getName().length; i++) {
System.out.format("URL: %s, Name %s, Version, %s", ui.getURL()[i], ui.getName()[i], ui.getVersion()[i]);
System.out.format("Downloading %s-%s", ui.getName()[i], ui.getVersion()[i]);
System.out.print("\n");
if(system_type.equals("Linux")) {
fpath = new File(System.getProperty("user.home") + "/.minecraft/mods/" + ui.getName()[i] + "-" + ui.getVersion()[i] + ".jar");
} else if(system_type.equals("Windows")) {
fpath = new File(System.getProperty("user.home") + "/AppData/Roaming/.minecraft/mods" + ui.getName()[i] + "-" + ui.getVersion()[i] + ".jar");
} else {
fpath = new File(System.getProperty("user.home") + "/.minecraft/mods/" + ui.getName()[i] + "-" + ui.getVersion()[i] + ".jar");
}
String url = ui.getURL()[i];
FileUtils.copyURLToFile(new URL(url), fpath);
}
}
public static void main(String[] args) throws Exception {
System.out.println("DEBUG START");
DownloadUpdate.runner();
}
}
Looking at the code, I cannot see a reason why the code is not outputting like expected; I am getting zero output on console, simply the line stating that the code is being executed. No exceptions either.
EDIT: variable ui is not being returned properly. For example, ui.getName[0] throws an ArrayIndexOutOfBoundsException, due to the length being zero. Seeing this, I now understand why the for loop isn't behaving as expected. Is this a scope issue? What am I missing here?
An obvious problem of your code is the use of ArrayUtils.add: you have to reassign its result to the input array, as you cannot modify arrays like lists in Java.
Use it like this:
releases = ArrayUtils.add(releases, latest.toString());
names = ArrayUtils.add(names, latest.getName());
and later in the for-loop:
urls = ArrayUtils.add(urls, url);
versions = ArrayUtils.add(versions, version);
Also you don't need to set the elements in each loop cycle to the result:
ui.setURL(urls);
ui.setVersion(versions);
Those would be sufficient once the for-loop has completed.
An alternative would be to first use List<String> instead of the arrays. If you have control over the UpdateInfo class, change it there to be lists too, otherwise create an array from the lists before you set it in UpdateInfo.
As a general advice I would recommend that you get rid of your static methods. Create instances and use your credentials (login, password, oauth) as member fields OR pass in even the whole GitHub instance. This way you would have an easier time writing proper tests.
I want to send some survey in PDF from java, I tryed different methods. I use with StringBuffer and without, but always see text in PDF in one row.
public void writePdf(OutputStream outputStream) throws Exception {
Paragraph paragraph = new Paragraph();
Document document = new Document();
PdfWriter.getInstance(document, outputStream);
document.open();
document.addTitle("Survey PDF");
ArrayList nameArrays = new ArrayList();
StringBuffer sb = new StringBuffer();
int i = -1;
for (String properties : textService.getAnswer()) {
nameArrays.add(properties);
i++;
}
for (int a= 0; a<=i; a++){
System.out.println("nameArrays.get(a) -"+nameArrays.get(a));
sb.append(nameArrays.get(a));
}
paragraph.add(sb.toString());
document.add(paragraph);
document.close();
}
textService.getAnswer() this - ArrayList<String>
Could you please advise how to separate the text in order each new sentence will be starting from new row?
Now I see like this:
You forgot the newline character \n and your code seems a bit overcomplicated.
Try this:
StringBuffer sb = new StringBuffer();
for (String property : textService.getAnswer()) {
sb.append(property);
sb.append('\n');
}
What about:
nameArrays.add(properties+"\n");
You might be able to fix that by simply appending "\n" to the strings that you collecting in your list; but I think: that very much depends on the PDF library you are using.
You see, "newlines" or "paragraphs" are to a certain degree about formatting. It seems like a conceptual problem to add that "formatting" information to the data that you are processing.
Meaning: you might want to check if your library allows you to provide strings - and then have the library do the formatting for you!
In other words: instead of giving strings with newlines; you should check if you can keep using strings without newlines, but if there is way to have the PDF library add line breaks were appropriate.
Side note on code quality: you are using raw types:
ArrayList nameArrays = new ArrayList();
should better be
ArrayList<String> names = new ArrayList<>();
[ I also changed the name - there is no point in putting the type of a collection into the variable name! ]
This method is for save values in array list into a pdf document. In the mfilePath variable "/" in here you can give folder name. As a example "/example/".
and also for mFileName variable you can use name. I give the date and time that document will created. don't give static name other vice your values are overriding in same pdf.
private void savePDF()
{
com.itextpdf.text.Document mDoc = new com.itextpdf.text.Document();
String mFileName = new SimpleDateFormat("YYYY-MM-DD-HH-MM-SS", Locale.getDefault()).format(System.currentTimeMillis());
String mFilePath = Environment.getExternalStorageDirectory() + "/" + mFileName + ".pdf";
try
{
PdfWriter.getInstance(mDoc, new FileOutputStream(mFilePath));
mDoc.open();
for(int d = 0; d < g; d++)
{
String mtext = answers.get(d);
mDoc.add(new Paragraph(mtext));
}
mDoc.close();
}
catch (Exception e)
{
}
}

Hello everyone and thank you in advance for any help that you may be able to give me. I am trying to create a java program that will pull names from a CSV file and take those names to generate custom outputs for text files. I am having a hard time being able to set a variable that I can use to grab the names that are being printed and using them to generate a text file by setting the name variable.
I am also going to need some help in making sure that it creates the amount of scripts for the amount of names in the CSV file. Ex. 7 names in CSV makes 7 custom .txt files, each with its appropriate name.
Any help is greatly appreciated!
Edit: I have updated my code to match the correction that was needed to make the code work.
It looks like you have some scoping issues. Whenever you declare a variable, it only exists within the boundaries of its closest set of braces. By declaring strar in your main method, the only place you can explicitly use it is within your main method. Your Printer() method doesn't have any previous mention of strar, and the only way it can know about it is by passing it as an argument to the function.
i.e.
Printer(String[] args)
Or, better yet:
Printer(String arg)
and then call it in your while loop with
Printer(strar[0]);
Also, your Printer method begins with a "for each" loop called on strar[0], which is not a valid target for a foreach loop anyway, because if I recall correctly, String isn't an Iterable object. If you implemented the Printer function in the way I recommended, you won't need a for each loop anyway, as there will only be one name passed at a time.
I have a problem. I wrote this code that reads a string from a txt file and I exported with the first method a int while the second one particular string. This method is already running but I have used the apache library, now I wanted to rewrite it in Java standard libraries. I have tried this, but I have had problems. Could someone help me? Thank you very much.
package ausiliare;
import java.io.File;

public class Read {
public static int getInt() throws IOException {
String content = null;
File folder = new File("C:\\Solution.txt");
content = FileUtils.readFileToString(folder) + "\n";
int outside = Integer.parseInt(content.substring(0,
content.indexOf("[")).trim());
return outside;
}
public static String getString() throws IOException {
String content = null;
File folder = new File("C:\\Solution.txt");
content = FileUtils.readFileToString(folder) + "\n";

// System.out.println(remainingString);
return remainingString;
}
public static String[] arg() throws IOException {
String[] strArray = getString().split(" ");
// System.out.println(Arrays.toString(strArray));
return strArray;
}
}
Ps: The input file is txt (for example):
50 [8,24,-22] [-8,34,12] [19,14,47] [-49,32,44] [-41,16,-6] [-49,-11,43]
Where the first method extracts the int 50 and the second extraction method extracts the remaining
content = new String(Files.readAllBytes(folder.toPath()),
StandardCharsets.UTF_8);
The missing part is the knowledge of the Files class.
There is a List<String> readAllLines too.
The character set parameter is optional and defaults to the current operating system's encoding - not very portable to other computers.
I'm trying to tokenize a large amount of text in Java. When I say large, I mean entire chapters of books at a time. I wrote the first draft of my code by using a single page from a book and everything worked fine. Now that I'm trying to process entire chapters things aren't working. It processes part of the chapter correctly and then it just stops.
Below is all of the relevant code
File folder = new File(Constants.rawFilePath("eng"));
FileHelper fileHelper = new FileHelper();
BPage firstChapter = new BPage();
BPage firstChapterSpanish = new BPage();
File[] allFiles = folder.listFiles();
//read the files into memory
ArrayList<ArrayList<String>> allPages = new ArrayList<ArrayList<String>>();
//for the english
for(int i=0;i<allFiles.length;i++)
{
String filePath = Constants.rawFilePath("/eng/metamorph_eng_"+String.valueOf(i)+".txt");
ArrayList<String> pageToAdd = fileHelper.readFileToMemory(filePath);
allPages.add(pageToAdd);
}
String allPagesAsString = "";
for(int i=0;i<allPages.size();i++)
{
allPagesAsString = allPagesAsString+fileHelper.turnListToString(allPages.get(i));
}
firstChapter.setUnTokenizedPage(allPagesAsString);
firstChapter.tokenize(Languages.ENGLISH);
folder = new File(Constants.rawFilePath("spa"));
allFiles = folder.listFiles();
//for the spanish
for(int i=0;i<allFiles.length;i++)
{
String filePath = Constants.rawFilePath("/eng/metamorph_eng_"+String.valueOf(i)+".txt");
ArrayList<String> pageToAdd = fileHelper.readFileToMemory(filePath);
allPages.add(pageToAdd);
}
allPagesAsString = "";
for(int i=0;i<allPages.size();i++)
{
allPagesAsString = allPagesAsString+fileHelper.turnListToString(allPages.get(i));
}
firstChapterSpanish.setUnTokenizedPage(allPagesAsString);
firstChapterSpanish.tokenize(Languages.SPANISH);
fileHelper.writeFile(firstChapter.getTokenizedPage(), Constants.partiallyprocessedFilePath("eng_ch_1.txt"));
fileHelper.writeFile(firstChapterSpanish.getTokenizedPage(), Constants.partiallyprocessedFilePath("spa_ch_1.txt"));
}
even though I'm reading all of the files in the directory where I expect my text to be, only the first coups of files are being added to the string that I'm processing. It seems like after a while the code will still run but it only adds characters to my string up to a certain point.
What do I have to change so that I can process all of my files at once?
This part
String allPagesAsString = "";
for(int i=0;i<allPages.size();i++)
{
allPagesAsString = allPagesAsString+
fileHelper.turnListToString(allPages.get(i));
}
will be really slow if your copying larger strings.
Using a StringBuilder will speed things up a bit:
int expectedBookSize = 10000;
StringBuilder allPagesAsString = new StringBuilder(expectedBookSize);
for(int i=0;i<allPages.size();i++)
{
allPagesAsString.append(fileHelper.turnListToString(allPages.get(i)));
}
Can't you process one page at a time? That would be the best solution.
