Problem in Reading and writing to process stream

I have created a java IDE which supports IO on the same window.,One touch compilation and execution.Applet can also be executed.
Also it provides Templates of various types which can be extended.
It has some problem in Conveying user inputs to the process created (I Create process for compilation and execution using ProcessBuilder).Any one interested to help can ask me for source code.mail me @ [email protected]

Yeah, well... good luck with that... :S

Problem on reading and writing from from a *.txt file

I get Problem on reading and writing from from a *.txt file. The following is the read() method...
The software said the DataInputStream is depreciated. Can anyone help me please?
public void read()
    File file = new File("C://Documents and Settings//Charles//My Documents//Brunel//EE2065//Assignment and Lab//Assignment 4 and Lab 4//data.txt");
    FileInputStream in = null;
    String str = "";
    try
      in = new BufferedReader(file);
      //in = new FileInputStream(file);
      for(;;)
        str = new BufferedReader(in).readLine();
        //str = new DataInputStream(in).readLine();
        if(str == null)
          break;
        System.out.print(str);
    in.close();
    catch(IOException e)
        System.err.println("execution error: " +e);
}

Thank you for your reply. I have made some change. However, there is an incompetable type found error.
in = new BufferedReader(new InputStreamReader(in));The following are all of the code.
public void read()
    File file = new File("C://Documents and Settings//Charles//My Documents//Brunel//EE2065//Assignment and Lab//Assignment 4 and Lab 4//data.txt");
    FileInputStream in = null;

I was able to resolve the reading part but ...I am getting exception while writing ..
it says parameter type conflict..
This is the code

Reading and Writing large Excel file using JExcel API

hi,
I am using JExcelAPI for reading and writing excel file. My problem is when I read file with 10000 records and 95 columns (file size about 14MB), I got out of memory error and application is crashed. Can anyone tell me is there any way that I can read large file using JExcelAPI throug streams or in any other way. Jakarta POI is also showing this behaviour.
Thanks and advance

Sorry when out of memory error is occurred no stack trace is printed as application is crashed. But I will quote some lines taken from JProfiler where this problem is occurred:
          reader = new FileInputStream(new File(filePath));
          workbook = Workbook.getWorkbook(reader);
          *sheeet = workbook.getSheet(0);* // here out of memory error is occured
           JProfiler tree:
jxl.Workbook.getWorkBook
      jxl.read.biff.File
             jxl.read.biff.CompoundFile.getStream
                   jxl.read.biff.CompoundFile.getBigBlockStream Thanks

Switcher - Reading and Writing External IEEE HDD's

Greetings,
i'm trying to read and write with my external ieee drive on windows and the mac pro. it's format is ntfs, and is read only on the mac pro.
i am admin and can't seem to change the permissions to read / write.
the over all idea is i need to go back and forth between operating systems reading and writing from both sides of the house.
here's a snapshot.
http://briankross.com/images/500GBIEEEHDD.jpg
Mac Pro Mac OS X (10.4.8)

Unfortunately, no. In order to convert the drive to FAT32 it must be re-partitioned which is a destructive process.

ImageIo: reading and writing a jpeg corrupts the image

Sometimes, ImageIo manages to read an image wrong. If I simply read() and write() the
image without any transformations, the image writtten will have its colors all wrong. The
output image format here doesn't matter.
An example image is: http://bram.name/~brama/pics/test.jpg
And output after reading and writing it: http://bram.name/~brama/pics/test_output.jpg
Is the image io lib to blame, or is it a broken image? The image displays fine in other programs.
Message was edited by:

Use this code to load the image.
From my experience it is much more stable and also faster.
My guess is that the problem is related to the ICC profile embeded in the JPEG.
JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder(new URL("http://www.stack.nl/~brama/pics/imageio.jpg").openStream());
BufferedImage image = decoder.decodeAsBufferedImage();

Lightweight library for reading and writing mp3-tags

Hi,
I'm currently evaluating libraries for reading and writing mp3-tags. All the projects I found so far where not maintained for a couple of years.
My question:
Is there currently a library, which one could call standard for this purpose
Cheers
Jonny

All the projects I found so far where not maintained for a couple of years.It may either be dead, or it may be so finished and free of bugs that no maintenance is needed anymore.
If you're occurring problems with it and if it is open source you can always consider taking a fork for own development.

Very slow painting while reading and writing doubles into file

for 15MB length file i = 7662080
for 50MB length file i = 12414368
Part of Code for writing into file follows like this:
try{
fos = new FileOutputStream("Angel.txt");
File f = new File("Angel.txt");
     if(f.length() >=4)
     f.delete();
fos = new FileOutputStream("Angel.txt");
dos = new DataOutputStream(new BufferedOutputStream(fos,1000000));
int x=0;
double y_last, y_new;
for(int j=0 ;j<i ;j++)
if(some condition)
y_new = ....;
try{
//previously in vectors
y_last = y_new;
vect.add(new Line2D.Double(x, y_last, x, y_new)_;
dos.writeDouble(y_new);
     }catch(Exception e){System.out.println(e);}
dos.close();
fos.close();
x++;
}catch(Exception excp){System.out.println(excp);}
part of code for reading from file follows like this:
public void paint(Graphics g)
try{
     double y1, y2 =0;
     Line2D.Double doub;
     raf = new RandomAccessFile("Angel.txt","r");
     dis = new DataInputStream(new BufferedInputStream(new FileInputStream(raf.getFD(),1000000)));
     raf.seek((rect.x*8));
     for (int i = 0/any value; (i < value as per choice); i++)
          g2.setStroke(new BasicStroke(0)); //2
          y1 = y2;
     y2 =dis.readDouble();
          doub=new Line2D.Double(i,y1,i,y2);
          g2.draw(doub);
dis.close();
     raf.close();
}catch(Exception excp){System.out.println(excp);}
I tried using Object Streams but NotSerializable Exception is thrown as Line2D.Double objects
are not serialized.
Any idea to make reading and writing into file specially from MB files faster is appreciated.

Why are you reading in the file in the paint method ?
Create your data once before painting.
I think you should explain what is your goal and what behavior you want.

Reading and writing a ByteArray

This question was posted in response to the following article: http://help.adobe.com/en_US/as3/dev/WS5b3ccc516d4fbf351e63e3d118666ade46-7d54.html

I believe that the example of Reading and Writing Objects needs a rewrite
First, the attempt to use comments to interleave a Flex-ified example with a Flash example of the uses of the ByteArray Class is a shortcut that ultimately fails. Take the time to create two, separately valid examples for the two different frameworks.
Second, the interlinea comments show a rather poor example of how to write clean code, and are entirely confusing to the person you you trying to help learn how to use your library. Look at the declaration of a variable called outFile:File, a comment about some function that is to be declared somewhere with the same name, outFile(), and indeed, if this code were to compile -- which I am sure it could not -- the compiler would see that you try to invoke an outFile() function. No one gets through an interview who writes code that way.
Third, I am not sure you understand how the readBytes and writeBytes methods work. In the upper example, where an order is being written to the file system, the writeBytes method uses data.length correctly. At the point in time that it is used, the XML object will have been written into the bytes:ByteArray, so it will have a proper length.
On the other hand, in the second half of the example, where the readBytes method similarly passes data.length, the reader has to be very lucky to note that at that point in time data.length will have a value of zero. The inBytes:ByteArray was only instantiated, not populated with anything, as, indeed it should not be, at that point in the logic flow. Most importantly, when the program does need to readBytes, there is no way for the program to know in advance what the length of the byte stream coming in from the file system will be. Your example would be more correct, and could make a useful point in showing that readBytes (data) is the correct way to pass the arguments because the default behavior will then be used and the default behavior will be to make data whatever length it needs to be in order to hold the content from the file system. The program can know the value of data.length after the read has taken place, but not before.

File importer detected an inconsistency in the file stucture of (file name). Reading and writing this file's metadata (XMP) has been disabled.

I have duplicated a project to work on another computer. The project opens fine but when I import new footage/audio files I get this message. "File importer detected an inconsistency in the file stucture of (file name). Reading and writing this file's metadata (XMP) has been disabled." Then I can't play my timeline and Premier Pro crashes. I have to force quit and restart my computer to continue working. What does this error really mean? How do you rectify?
Our workflow requires that we duplicate projects to make updates because we are frequently revising but need to keep original project unchanged and intact.

I have a similar issue and message , but occurs when I import AVI clips from OnLocation CS4 to Premier Pro CS4.

Quickest method for reading and writing files

Hi
I need help regarding file operations.(Reading and Writing). Currently I am using BufferedReader and BufferedWriter to read and write files. But the files (XML) are very huge files(from 30 -50 mb). This is slowing the application to a great extent. Is there any other approach to perform the above mentioned operations on XML files in a fast manner.
Thank You

Data reading and writing problem? how to set " Read from Measurment File express.vi" 's readout datasize?

Dear all,
I want to use Labview to process a data.
Now I have a array in a text file.
this array is very very big. which is at least row*col = 6 * 100000;
the column size always 6,
but the row size is ramdom, some times is very big, like bigger than 65535,
when I use "read from measurement file express.vi" to read this file, the array I could get always 6*5339, I don't know why. the column size is always 5339.
and then I delete the 1st row of the array and then write into a txt file via "write measurement file express. vi", it takes a very long time. almost computer has no response. after a while, no file was creat to record the data.
is there an efficient way to process such big data file and store the processed file into a new file
thank you very much
Jack

Hello,
There’s no real efficient way to read the file if you don’t
know exactly how many rows of data you have.
Your going to just have to read a row at a time and add the results to
the end of an array (granted for the clever programmers there are some more
efficient ways to do this than just with ‘build array’). I would start by asking you how much
information you know about the file and what the exact structure of it is (i.e.
is it a binary file, a tab delimited file, or a LVM file)? Could you provide a screenshot of the code
you are running? If you provide a little more information on the file structure
we might be able to contribute some additional information.
Look forward to hearing back from you-

Reading and writing to and from a file to a form

Hi there
I would like somebody to send me a code example,
showing me how to reading records from a file to a form,
and writing records to the same file from the same form.
I know that I have to use sycronize, but I just have not been
successful. I can constract forms, go from form to a form,
do buttons, do text fields. I can even read and write from and
to files. However I cannot do is write from a file to a form and
from a form to a file.
could somebody please explain how this done, and could you
please give me a code example. All the books seem to either
deal with forms or with files. None seem to combine both.
I am sure it is very ease to do if ONLY I knew how!!!
thank you very much in advance for you help.

I understand that code and I have used it before, however thanks for
trying to help me, it is really appreciated. However, that is not my
problem. I can read and write from a file to the console and vice versa.
what I cannot do, no matter how hard I try, is to write from a file, and
output it in.
I will tell you how far I have got.
