How to read a text file and only output every other line?

I am just writing a program that reads a file but outputs only every other line. Any ideas...please? thanks

I'd start with something like this and expand on it as you go:
File file = <whatever>;
BufferedReader in = null;
try {
    in = new BufferedReader(new FileReader(file));
    int i = -1;
    for (String line = null; (line = in.readLine()) != null; ) {
        if ((++i % 2) == 0) {
            System.out.println(line);
} catch (IOException e) {
    e.printStackTrace();
} finally {
    if (in != null) {
        try {
            in.close();
        } catch (IOException e) {
}Shaun

How to Read the "text file and csv file" through powershell Scripts

Hi All
i need to add a multiple users in a particular Group through powershell Script how to read the text and CSV files in powershell
am completly new to Powershell scripts any one pls respond ASAP.with step by step process pls
Regards:
Rajeshreddy.k

Hi Rajeshreddy.k,
To add multiple users to one group, I wouldn't use a .csv file since the only value you need from a list is the users to be added.
To start create a list of users that should be added to the group, import this list in a variable called $users, the group distinguishedName in a variable called $Group and simply call the ActiveDirectory cmdlet Add-GroupMember.
$Users = Get-Content -Path 'C:\ListOfUsernames.txt'
$Group = 'CN=MyGroup,OU=MyOrg,DC=domain,DC=lcl'
Add-ADGroupMember -Identity $Group -Members $Users

What I wanna do is to read all the data above and buffer them in a queue for each user( there are only 10 users in total).
I already created a class called Class packet:
public class packet {
    private int timestamp;
    private int user_id;
    private int packet_id;
    private int packet_seqno;
    private int packet_size;
    /** Creates a new instance of packet */
    public packet(int timestamp,int user_id, int packet_id,int packet_seqno, int packet_size)
        this.timestamp = timestamp;
        this.user_id=user_id;
        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.

How to read several text files at a time

Dear all
Read and write one text file is not a problem, but what confusies me is how to read several text files at one time, in the meanwhile,
is it possible to display the name of the text file?
For example, assuming I want to load file" cha 1, cha 2 , cha 3, " at one time and show their names, how to hadle with it
I have reviewed some files and it is not helpful

Either with a 'for' loop like in the lib you have attached, or like this attached VI
that's it

See in this case as you are dealing with Files and database. you need read the File by using the I/O Streams. if you have to select some particular values you can go Random access file.Once you have retrived values. You can go for the second part that is make a jdbc connection to database, and use simple SQL statements to populate those values into the table.
How this will give you a better picture

How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.
Regards,
I-Talk

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

Read multiple text files and sort them

I am trying to read multiple text files and store the data from the file in vector.
but for days. I am with no luck. anyone can help me out with it? any idea of how to sort them will be appreciated.
Below is part of the code I implemented.
public class packet {

        timestamp = timestamp0;
        user_id=user_id0;
        packet_id=packet_id0;
        packet_seqno=packet_seqno0;
        packet_size=packet_size0;
    public void setTime(int atimestamp)
        this.timestamp=atimestamp;

    public String toString()
        return timestamp+"\t"+user_id+"\t"+packet_id+"\t"+packet_seqno+"\t"+packet_size+"\t";

Issue : Read a text file and print the same

Hi, My requirement is to read a text file and print it the same way.
import java.io.BufferedReader;
import java.io.FileReader;
public class CatFile {
public static void main(String[] args) throws Exception
     FileReader file = new FileReader("D:/Test/Allfiles.txt");
     BufferedReader reader = new BufferedReader(file);
     String text = "";
     String line = reader.readLine();
     while (line != null)
          text += line;
          line = reader.readLine();
     System.out.println(text);
The text file i used contains
A
B
C
but my output is ABC.
What change should be made to print it the same way in the txt file ?

Hi EJP,
I modified the code based on your suggestion and now its working as expected. Thanks
Modified code :
import java.io.BufferedReader;
import java.io.FileReader;
public class CatFile {
public static void main(String[] args) throws Exception
     FileReader file = new FileReader("D:/Test/Allfiles.txt");
     BufferedReader reader = new BufferedReader(file);
     String text = "";
     String line = reader.readLine();
     while (line != null)
          System.out.println(line);
          line = reader.readLine();
          text += line;
}

How to read a text file through pl/sql

pl/sql runs inside the database. so your file also should be on the database server file system for you to be able to read.
check out UTL_FILE package. This is the database package to read/write files on the database server.

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...

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?

without what arguments?Without any arguments. If there are no arguments, there are no arguments of any kind. If you have a zoo with no animals in it, it's not meaningful to ask whether the animals which are not there are zebras or elephants.
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.

How to read two text files using the Read from spreadsheet.vi and then plot it

I need to read two text files using the read from spreadsheet function and then plot these files over time.
The file with the .res extention is the RMS values (dt and df) and the second file contains the amplitude of a frequency spectrum.
I really appreciate any help..thanks
