File Read and Extract

Hi,
I have a script which runs and generates log files. Rather than manually read through these log files, I'd like to code a program which will take the file, read through it and extract the data I wish to extract.
For example, it may read:
bla bla bla
bla bla bla
23/03/05 - 151105 Files
bla bla bla
23/03/05 - Elapsed Time: 3m 50s
bla bla bla
24/03/05 - 51250981502 files
bla bla
24/03/05 - Elapsed Time: 59m 12s
bla bla
etc etc.
So I want to ignore the "bla bla bla", pick out my keywords, such as file, time and print out the number next to it, preferably to a nice little html file or something :)
I am able to read files and I think I can pick out keywords using string tokenizers, although this is more advanced than tokenizers I've used before. I used a buffer to split the file and read it line by line.
I'm pretty stumped, although this seemed like a straight forward thing to do at the time....
Any advice to get me going?
Thanks!

you could use a reg ex to match on xx/xx/xx and still read line by line.
or you could use Integer.parseInt and always parse the first two characters of a line, if they parse they are integers, but maybe blah has integers in the first two positions as well.

File reader and comparing words

hi, im currently trying to create a project and i need a little help to get it started!
What i need to do is create an application which can read a text file. I also need to have a list of words already in the application, and if a word in the list is also in the text file, id like this to be printed in the terminal.
can anybody help me out with how to start this? ive been looking for relevant posts, and there seems to be alot of things on file reading and comparing words, but they r pretty difficult to follow and not really the same as what im looking for.
thanks for your help!
Torre

You can place a for loop within a for loop to to compare every word in the temp array with every word in the other array.
try {
String[] array = new String[] {"wow", "cool"};
BufferedReader in = new BufferedReader(new FileReader("text.txt"));
String str;
while ((str = in.readLine()) != null) {
String [] temp = null;
temp = str.split(" ");
for (int i = 0 ; i < temp.length ; i++) {
for(int j = 0; j < array.length; j++) {
if (array[j].equals(temp)) {
System.out.println(temp);
} catch (IOException e) {
} finally {
//Always close your resources in your finally block... good coding practice.
in.close();

Problem With File Reading And Sorting

I'm having problems with a particular task. Here is what I have to do:
Write a program which reads 100 integers from a file. Store these integers
in an array in the order in whcih they are read. Print them to the screen.
Sort the integers in place using bubble sort. Print the sorted array to the
screen. Now implement the sieve of Eratosthenes to place all prime numbers
in an ArrayList. Print that list to the screen.
Here is the code I have so far:
import java.util.ArrayList;
import java.io.*;
public class Eratosthenes
    private ArrayList numbers;
    private String inputfile1 = "numbers.txt";
    public Eratosthenes()
        numbers = new ArrayList();
    public void readData()
        try {
            BufferedReader reader = new BufferedReader(new FileReader(inputfile1));
            for(int i = 1; i <= 100; i++) {
                String temp = reader.readLine();
                numbers.add();
        catch(Exception e)
This is the file reading part I have done but it doesn't recognise the line numbers.add() . It brings up the error - 'Cannot resolve symbol - method add(). Thats the first problem I have, can anyone see any way to fix it and to achieve the task. Also can someone help with the structure of a bubble sort method and a sieve of Eratosthenes method as I have no clue whatsoever. Any help will be greatly appreciated.

Ok, I've done that but I'm having another problem. When I'm printing an output to the screen, it prints 100 lines of integers and not 1 line of 100 integers. Can you see the problem in the code that is doing this?
import java.util.ArrayList;
import java.io.*;
public class Eratosthenes
    private ArrayList numbers;
    private String inputfile1 = "numbers.txt";
    public Eratosthenes()
        numbers = new ArrayList();
    public void readData()
        try {
            BufferedReader reader = new BufferedReader(new FileReader(inputfile1));
            for(int i = 1; i <= 100; i++) {
                String temp = reader.readLine();
                numbers.add(temp);
                System.out.println(numbers);
        catch(Exception e)
}

Large File Reading and Processing

Hi:
Suppose I have a file much larger than my computer's memory e.g. say on a Windows XP system, the memory is 256 MB RAM and the file size is 1 GB on disk. Now if I want to create a File object and read from this file, is this possible to do? If yes, how about the performance?
I understand that this is more of an Operating System question but nevertheless it affects the Java process.
Thanks!
Rahul.

If you mean, you plan to read the whole file into memory, then:
Theoretically possible, sure. The process would be much bigger (in terms of memory used) than the amount of memory available, which means that it would start swapping out to disk, and that would reduce performance, although to what extent depends on XP's virtual memory implementation, which I know nothing about.
But if all you mean is that you want to create a File object and read bits of the file, it won't make any difference. File represents a name or description of a file, not the file itself (you can create File objects for files that don't exist). So it doesn't need to read the whole into memory just to create a File object. You can easily create a File object for the huge file, and then read it in line by line, throwing away old lines as you go, and you won't use up very much memory at all. (Unless, of course, there's some horrible weird artifact of XP that I'm not aware of.)

How to modify a datafile using file read and file write

I have a datalog file containing port and DMM setup information. I want to read this file into an aray, update or modify it, and write it to a file. I can read the file in, but I am at a loss on how to modify it since it is stored in an indicator. Any suggestions?

The simplest thing is to replace your indicator by a control, and to use a local variable to write your data into the control.

Csv file reading and voltage and current plotting with respect to time samples XY plotting

Hallo,
I've been struggling with reading a comma separated value (csv) file from another instrument (attached). I need to plot this data for analysis. I have 5 column of data with numbers of rows, the first three row is the information of the measurement. I want to read 4th row as string and rest of the row as numbers. I want to plot 2nd column (i1) with respect to TIMESTAMP; 4th column(u2) wrt TIMESTAMP. And finally plotting i1 (x-axis) vs.. u2 (y-axis) in labview. Could anyone help me.
In excel its so easy to plot but I don't know how its done in labview.

Start by opening the file. Then use the Read Text File function. You can right-click on it and configure it to read lines. First make it read 3 lines (this is your extra header data). Then make it read a single line. That will give you your channel names. Then read the rest of the file (disable the read by line and wire a -1 into the number of bytes to read). Then use the Spreadsheet String to Array function to give you your data.
I would recommend going through the LabVIEW tutorials if you are really new at this.

How do I protect File (read and copy only)

I have created a photo file that I want my kids to be able to see and copy( make an imovie or slideshow with)but not write onto. This way as I update the file with more pictures I can copy the new items over easily without creating copies of pictures. The file size is currently 250GB and to re-write the entire folder each time takes 8 hours and it might only take minutes if it only has to write the new pics. My hope is to be able to drag the file onto their drive and then for the system to ask if I want to replace or ignore existing files and just write the new ones. I want to be the only one that has the capability to do this. Help

If you control their Apple menu -> System Preferences -> Accounts to have parental controls, you can keep that file inside a read only folder that you create for them to access. That's true for nearly every version of Mac OS X.
If you are able to boot into Mac OS 9 on any of your machines, you will have to setup those accounts to boot via Apple -> Control Panels -> Users and Groups to have read only folders.
Secure your account with a password that no one can guess. Birthdays, names, foreign language words are not good passwords. A mixture of consonants, numbers, and symbols are best, and at a minimum 8 characters.

Text file reading and writing problem

Hello ! i am working on an electronic diary project and i am using Netbeans for that... i have finished all the rest but i am stuck into the saving of the appointments which i have been making.. i am using text files to save the entries ...what i am doing currently is that i am creating a file of every date which a user selects in the combobox.but if i want to add more appointment on the same date , then it overwries the previous one. i need to write something which can store multiple appointments in the same file.
the writing code is:
try {
String aa = jTextField1.getText();
String ab = jTextField2.getText();
String ac =(String)jComboBox2.getSelectedItem();
String ad =(String)jComboBox3.getSelectedItem();
String ae = jTextField5.getText();
String af =(String)jComboBox1.getSelectedItem();
String ag = jTextArea1.getText();
String outputFileName = ab+ac+ad+".txt";
FileWriter outputFileReader = new FileWriter(outputFileName);
PrintWriter outputStream = new PrintWriter(outputFileReader);
PrintWriter outputStream1 = new PrintWriter(outputFileReader);
PrintWriter outputStream2 = new PrintWriter(outputFileReader);
PrintWriter outputStream22 = new PrintWriter(outputFileReader);
PrintWriter outputStream3 = new PrintWriter(outputFileReader);
outputStream.write(aa);
outputStream1.write(ae);
outputStream2.write(af);
outputStream3.write(ag);
outputStream.close();
} catch (IOException e) {
System.out.println("IOException:");
e.printStackTrace();
when i read the code , it doesnot reads the one which i store the text in new line...
thanks

Hi Dear
Actually apending in your file is False so that it is overwriting this. do one thing open append option then it will add your data. for this just user true as the parameter with file name as i write in the below line. bedefault overwriting is false. you have to make this true.
BufferedWriter out = new BufferedWriter(new FileWriter("Out.csv",true));
try this your problem will solve.
