Creating a file from a Java Program

Hi all,
if I want to store a byte array to a file somewhere in the middle of my program... is it possible to create the file inside my Java program, i.e. the file will be created during the execution of my program, and then write this byte array into it? The name of the file to be created is predefined by me, and not thru user input.
If so, does anyone have a sample source code to show me? or redirect me to somewhere ?
Thanks in advance!
Joe

You can take a look at the File, FileOutputStream, FileInputStream classes. A simple one will be like:
byte[] ar = {12,13,14};
File file = new File("wee.dat");
if (!file.exists())
try
FileOutputStream fos = new FileOutputStream(file);
fos.write(ar);
}catch (IOException io){}
else
...

  • How to compile and run a .java file from another java program

    hello,
    can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?

    Well a smarter way of implementing this is by using a solution provided by Java Itself.
    If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)
    http://java.sun.com/javase/6/docs/api/javax/tools/package-summary.html
    How do i do that ??
    Check out the below articles which would help you of how to do that
    http://www.ibm.com/developerworks/java/library/j-jcomp/index.html
    http://www.javabeat.net/javabeat/java6/articles/java_6_0_compiler_api_1.php

    Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.
    Hope that might help :)

  • How can I execute a batch file from my java program

    Hi,
    Can someone help me or direct me to a link,
    How can I execute a DOS batch file from my java program?
    Thanks

    You will need to grab a handle to the process's
    outputstream so u can see its output.The OP didn't mention any output from any batch file;
    nor any input for that
    matter,so lets not complicate matters here for now
    ok?Actually I think this is essential to see whether it works or not. It's either that or do some manual check to see whether it ran, which is not exactly elegant, and in some cases this may not be easier than simply writing the output stream code, or in fact it may be impossible to check manually.
    I'm sure it wasn't intentional that your post appeared to be bristling with attitude.

  • How to invoke the .bat(batch file ) from the java program

    i want to run some commands when i run one java program.
    I wrote those dos commands on the batch file and i want to include the bat file in the java program so that i can execute the bat file when i run the java program.
    tell me the way that i can run my bat file inside the java program.

    i tried this :
    a .bat file named test.bat, with this code : copy test.bat test2.bat
    a java class, Test.class, in the same directory

  • How to create .exe file of the java program you create?

    This must be the qustions asked several time on the forums.So here it is again.
    This sounds absurd to some developers here cause you'll say just create jar file and distributre to usr but sometimes there is not possiblity of having runtime environment in windows computers.So if we can bundle the enviroment and the setup together then packing into exe and then distribute like most of commercial java application sounds better.But the problem is how to do that?
    Ok creating exe will increase the size but that doesn't matter,if there is any freeware tool to accomplish just that?

  • How do I call another exe file from a Java program?

    Hi,
    I am doing a simple IDE (text editor/interpreter) for a simple programming language we are developing. It will be submitted as our project for this semester. I created an exe file (in C) which will be used as the interpreter. How do I call the interpreter from my IDE? The interpreter should run when the user clicks a button (i.e. the "Run" button). I've tried the Java Runtime class but it doesn't work. Anyone who knows how to do it?
    Thanks!

    I first tried to do a simple program that calls system commands such as dir, cd <dir>, etc.
    I do not have the exact code right now but as far as I can remember, here's what I wrote:
    class Sample{

           BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
           String command;

  • How to read files on server from a java program?

    Hello,
    I am fairly new to JSP programming. I have an issue with reading files. I am trying to call method of a normal java file from a jsp program. The method I am trying to call does some IO operation on Files. I have the files in the same directory as my class files on server that is in WEB-INF/classes folder. In my java program, I am giving just the file name to open because the files and the classes are in the same directory. But this is not working.
    What exactly should I do to read a file from a java program, that is running on the server?
    Any help is appreciated.
    Thanks,
    Krishna

    String realFilePath = application.getRealPath("/WEB-INF/myFile.txt");
    File fileToOpen = new File(realFilePath);
    out.println(fileToOpen.getAbsolutePath() + ": exists? " + fileToOpen.exists());in this case "application" is a reference to the ServletContext.
    It is an implicit variable in a JSP. In a servlet:
    ServletContext application = getServletConfig().getServletContext();

  • Launch 2 batchs from a java program

    Hi,
    My pb is the following one:
    I launch a batch file from my java program. This batch launch another program. But it seems that the java program take back the hand and stop the execution of the last program.
    How can I make the java program waiting?
    Thanks in advance

    Thanks Felipe.
    I've tried your suggestion and I've discerned the real bug. In fact, it's the program that I launch through the batch file which don't perform.
    Here is my batch file:
    C:\program files\pvcs\vm\win32\bin\pcli.exe run -sC:\program files\pvcs\vm\win32\bin\noexiste.pcli %1 %2 %3
    In fact, it has to launch pcli.exe, which has to launch a script.
    The pb is that when I run the batch file manually, it works. So, it comes from the java prg. Here is the command lines in my program java:
    try
    String cmd = "C:/Progra~1/Pvcs/Vm/Win32/Bin/transfert.bat";
    String[] cmdArray = { cmd, Str_LabelModule, Str_FichierSauvegarde, Str_AccesArchive };
    Prc_MyProcess = Rt_MyRuntime.exec(cmd);
    System.setProperty("ATTENTE", "VRAI");
    while(!b_stop)
    if(!System.getProperty("ATTENTE").equals("VRAI"))
         b_stop = true;
    else
         Thread.sleep(1000);
    }catch (Exception exc) {exc.printStackTrace();}
    I tried this program with a simple batch (echo %1 %2 %3 > c\toto.txt) and it works.
    Have you an explanation for this?
