Find word in text file and count specific words

now I'll try to explain what I need to do. I have file.txt file, It looks like:
John //first line - name
One
Three
Four
Peter //first line - name
Two
Three
Elisa //first line - name
One
Three
Albert //first line - name
One
Three
Four
Nicole //first line - name
Two
FourSo I have program's code:
public class Testing {
        public static void main(String args[]) throws Exception {
            Scanner input = new Scanner(System.in);
            System.out.println("Select word from list:");
            System.out.println();
            try {
                FileReader fr = new FileReader("src/lt/kvk/i3_2/test/List.txt"); // this is list of words, everything all right here
                BufferedReader br = new BufferedReader(fr);
                String s;
                while((s = br.readLine()) != null) {
                    System.out.println(s);
                fr.close();
                String stilius = input.nextLine();   // eneter word which I want to count in File.txt
                BufferedReader bf = new BufferedReader(new FileReader("src/lt/kvk/i3_2/test/File.txt")); // from this file I need to count word which I entered before
                int counter = 0;               
                String line;
                System.out.println("Looking for information");
                while (( line = bf.readLine()) != null){
                    int indexfound = line.indexOf(stilius);
                    if (indexfound > -1) {
                         counter++;
                if (counter > 0) {
                    System.out.println("Word are repeated "+ counter + "times");}
                    else {
                    System.out.println("Error...");
                bf.close();
            catch (IOException e) {
                System.out.println("Error:" + e.toString());
        }This program counting specific word (entered by keyboard) in file.txt.
I need to make this program: for ex.: if I enter word: One It must show:
Word One repeated 3 times by John, Elisa, AlbertAll what I need to elect by who this word repeated. But I don't know really how to make It, maybe LinkedList or I dont know, someone could help me?
Thank you very much.

or I dont know, someone could help me?You need to introduce a variable to store the actual name which must be resetted if an empty line is found and then gets assigned the verry next word in the file.

  • Read Text file and count occurences of certain string

    Hello,
    I have a text file with lines of data in it. I would like to read this text file and count how many lines match a certain string of text. 
    For example my text file has this data in it.
    dog,blue,big
    dog,red,small
    dog,blue,big
    cat,blue,big
    If the certain string of text is "dog,blue,big" then the count would return "2".

    Unexpected Essbase error
    And also it will count the # of times the word error appear in a log file.
    You may use batch file or Perl script to complete this task.
    e.g. in the log file - It will flag yes that keyword "Unexpected Essbase error" found and word error occurs 9 times.
    Pls help me in know process to achieve above requirement.
    and pls let me know what is perl scripting ?
    Thanks in Advance
    Regards,

    Sorry but it sounds like you have been asked to do something and you have pasted the requirement on the forum, have you done any research to find out which scripting language you are going to use or any find examples, there are so many differents examples and help on the internet it just takes a little bit of time and investment.

  • Reading a text file and transferring values into array

    Hi,
    I have a problem. So what I am trying to do is that, I read a text file and insert specific values from the text file into an array for future needs.
    But I have to make sure that there is no duplicate entries. So thats what I have but, my method takes forever to finish...
    here is my code:
    String nomFichier = "Test_" + numTest + "_" + date + ".txt";
            String ligne = "";
            int z = 0;
            int j = 0;
            BufferedReader lecteurFichier = new BufferedReader(new FileReader(nomFichier));
            while ((ligne = lecteurFichier.readLine()) != null) {
                if (z > 3)
                    String valeur = "";
                    String dist = "";
                    boolean unique = true;
                    String [] chiffre = ligne.split(";");
                     if (intervalleAnalyser == 1)
                        valeur = chiffre[3];
                        dist = chiffre[4];
                    if (intervalleAnalyser == 2)
                        valeur = chiffre[2];
                        dist = chiffre[4];
                    if (intervalleAnalyser == 3)
                        valeur = chiffre[1];
                        dist = chiffre[4];
                    if (z == 4) {
                        intervalleDiagramme[j] = valeur;
                        j++;
                    if (z > 4) {
                        for (int i = 0; i < intervalleDiagramme.length; i++)
                             for (int x = 0; x < i; x++)
                                 if(intervalleDiagramme[i] == intervalleDiagramme[x])
                                    unique = false;
                        if (unique)
                            intervalleDiagramme[j] = valeur;
                        j++;
                z++;
            lecteurFichier.close(); // toujours fermer le fichier

    Hi,
    Thanks for your reply,
    1) Yeah I have a method that asks the question and assigns it to a variable.
    2) Well the z will stop once there is no lines to read no?
    for the set.add(), I am not that familar...
    I changed bit a code and I have this now:
    if (z > 4) {
                        for (int i = 0; i < intervalleDiagramme.length; i++)
                            System.out.println(intervalleDiagramme);
    if(intervalleDiagramme[i].equals(valeur))
    System.out.println(intervalleDiagramme[i] + " " + valeur);
    unique = false;
    if (unique)
    intervalleDiagramme[j] = valeur;
    EDIT:
    I figured a way to assign " " to all the values in my array. But I get this error:
    Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 380
    at TP3.lireFichier(TP3.java:305)
    And my line 305 is: intervalleDiagramme[j] = valeur;
    EDIT2:
    So ok I found my mistake and corrected it. But I want to know is there a way of doing this without setting the size of the array? because sometimes there needs to be 21 values sometimes 19 and sometimes 20....
    If I take out: = new String [21] out I get a NullPointer error...

    Sorry I'm just beginning coding and I'm still a noob. Any help is appreciated. Thank you!

    Ok, so if I'm following this correctly you should be able to just loop through all of the files in that folder whose file name matches the pattern and then read the first 22 lines, recording only the first and the last.
    Exactly how you store the animal data probably depends on how you are going to display it and what else you are going to do with it.  Is there anything other than name and cage number that should be associated with each animal?
    You might want to make a dataset with a datatable to describe the animal, or you might write a class, or you might just use something generic like a Tuple.  Here's a simple class example:
    Public Class Animal
    Public Property Name As String
    Public Property Cage As String
    Public Overrides Function ToString() As String
    Return String.Format("{0} - {1}", Name, Cage)
    End Function
    End Class
    With that you can use a routine like the following to loop through all of the files and read each one:
    Dim animals As New List(Of Animal)
    Dim folderPath As String = "E:\Furry Friends Animal Shelter Solution\Furry Friends Animal Shelter\"
    For Each filePath As String In System.IO.Directory.GetFiles(folderPath, "Report Q?.txt")
    Using reader As New System.IO.StreamReader(filePath)
    Dim lineIndex As Integer = 0
    Dim currentAnimal As New Animal
    While Not reader.EndOfStream
    Dim line As String = reader.ReadLine
    If lineIndex = 0 Then
    currentAnimal.Name = line
    ElseIf lineIndex = 22 Then
    currentAnimal.Cage = line
    Exit While
    End If
    lineIndex += 1
    End While
    animals.Add(currentAnimal)
    End Using
    Next
    'do something to display the animals list
    Then you might bind the animals list to a ListBox, or loop through the list and populate a ListView.  If you decided to fill a datatable instead of making Animal instances, then you might bind the resulting table to a DataGridView.
    There are lots of options depending on what you want and what all you need to do.

    First of all, when posting code, put it between two tags.
    Second of all, the pipe is a special character in regex, so you need to escape it as
    .split("\ \|");
    Erh. So 2 backslashes before the pipe character. Stupid forum won't post it.

            this.packet_id=packet_id;
            this.packet_seqno=packet_seqno;
            this.packet_size=packet_size;
    }then I wanna to create another Class called Class user which I can create a queue for each user (10 users in total) to store type packet information. the queue for each user will be in the order by timestamp.
    any idea and sample code will be appreciated.

    Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
    Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

  • Take an existing text file and modify values

    I’m looking to take an existing text file and modify certain values inside of it. Then save it to a new file, with all the same formatting as the original. The file format is not uniform and can change.
    Basically the file is:
    Random numbers and letters of unknown length for an unknown number of lines.
    Label="Test_#"
    Description
    String
    X=123
    Y=456
    Z=-789
    20 lines of strings with numbers in them
    Label="Test_#2"
    Description
    String
    X=-1232
    Y=4562
    Z=7892
    Then it repeats a set number of times.
    I want to modify the X Y and Z = values for each Test_#.
    I’ve managed to import the important values into a numeric array and I have a different array with values that will replace the existing ones. I’m having troubles replacing the existing ones. There are no zeros before or after the existing numbers so they are all different lengths.
    If anyone has any sample code that does anything similar please post it. I’m sure someone has done something like this in the past. 
    Solved!

    I just thought I would throw this out there.  Can you make the .txt file tokenized?  This would make searching for specific parameters much easier.

  • Where does this java program read a text file and how does it output the re

    someone sent this to me. its a generic translator where it reads a hashmap text file which has the replacement vocabulary etc... and then reads another text file that has what you want translated and then outputs translation. what i don't understand is where i need to plugin the name of the text files and what is the very first line of code?

    does it prompt me to give it a text file name?Apparently.
    when i run it this is all i get:
    usage: Translate wordmapfile textfile
    Press any key to continue...Right. And "wordmapfile" is almost certainly supposed to be a file that holds the word map, and "textfile" is almost certainly the file of text that it's going to translate.

    Reader doesn’t create pdf files. You can use Acrobat (ask in that forum) to create pdfs. You can subscribe to the Adobe PDF Pack which has a create pdf functionality (please ask in that forum), or you can use a third party utility such as ghostscript, cutepdf, or Microsoft’s own PDF creation capability. For third party pdf creation you will need to ask in a forum dedicated to that software as fellow users of Reader are unlikely to have the knowledge to help.

    I haven't looked closely, but my spidey sense tingles at this:
    new FileOutputStream(MPath)This will clobber (erase) the previous contents of the file. Open in append mode:
    new FileOutputStream(MPath, true)Of course, if the file exists before you run this code, you will end up append to the original contents. If that is not wanted, consider using File's delete method first.

  • VB Script to find the last modified file and time in a directory

    Hi,
    I am new to VB script i need a script to find the latest modifed file and last modifed time in a directory(Contains  folders and sub folders inside it). it has to go through all the folders and get the latest file and last modifed time.

    Thanks it worked for me Get-ChildItem C:\Users\sujith.reddy.komma\Desktop\Suj1\* -recurse |?{-not $_.PsIsContainer} |Sort LastWriteTime -desc | select -first 1 now in my script i have hard coded the directory i need to run this script in different

  • Reading from a text file and displaying the contents with in a frame

    Hi All,
    I am trying to read some data from a text file and display it on a AWT Frame. The contents of the text file are as follows:
    pcode1,pname1,price1,sname1,
    pcode2,pname2,price2,sname1,
    I am writing a method to read the contents from a text file and store them into a string by using FileInputStream and InputStreamReader.
    Now I am dividing the string(which has the contents of the text file) into tokens using the StringTokenizer class. The method is as show below
    void ReadTextFile()
                        FileInputStream fis=new FileInputStream(new File("nieman.txt"));
                         InputStreamReader isr=new InputStreamReader(fis);
                         char[] buf=new char[1024];
                         isr.read(buf,0,1024);
                         fstr=new String(buf);
                         String Tokenizer st=new StringTokenizer(fstr,",");
                         while(st.hasMoreTokens())
                                          pcode1=st.nextToken();
                               pname1=st.nextToken();
              price1=st.nextToken();
                              sname1=st.nextToken();
         } //close of while loop
                    } //close of methodHere goes my problem: I am unable to display the values of pcode1,pname1,price1,sname1 when I am trying to access them from outside the ReadTextFile method as they are storing "null" values . I want to create a persistent string variable so that I can access the contents of the string variable from anywhere with in the java file. Please provide your comments for this problem as early as possible.
    Thanks in advance.

    If pcode1,pname1,price1,sname1 are global variables, which I assume they are, then simply put the word static in front of them. That way, any class in your file can access those values by simply using this notation:
    MyClassName.pcode1;
    MyClassName.pname1;
    MyClassName.price1;
    MyClassName.sname1
