thanks in advance
If you Google, you will find a commercial Java compiler available for 60-day free trial. It provides detailed instructions on how to get started with compiling your code. The 60 days should be enough time for finishing your school work.

Java Program- File & Directories
Hi, I was wondering if anyone can helpe me out with this program. I have a good start on it but keep on getting errors.
The task is to read one command line argument that contains the directory name. Using recursion, traverse the directory and all its sub-directories. Then for each file in each direcotry create an object class which keeps track of the file name (absolute path) and the size of the file, then adds the object to a Vector. Once thats done, i have to print a report showing each file name and size in decending order of file size. I have attached what i have so far... if ne one can help me i'll be verryyyyy greatfulll
for(i=0; i<fileList.size(); i++){
File file = (File)fileList.get(i);
System.out.print(file.getAbsolutePath());
System.out.println("Length of File: " + file.length());Hi,
First you have to recursive method to build your file List and then sort the list and print. You can get a good start from the following code:
public void buildFileList(File file, ArrayList list)
list.add(file);
if(file.isDirectory())
File[] files = file.listFiles();
for(int i=0; i < files.length; i++)
buildFileList(files, list);
public void printFiles(ArrayList list)
Comparator cmp = new Comparator()
public int compare(Object o1, Object o2)
if( ((File)o1).length() > ((File)o2).length() )
return -1;
else if( ((File)o1).length() < ((File)o2).length() )
return 1;
else
return 0;
Collections.sort(list);
for(int i=0; i < list.size(); i++)
System.out.println(((File)list.get(i)).getAbsolutePath()); -
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
http://books.google.com/books?id=WVbpv8SQpkEC&pg=PA155&lpg=PA155&dq=%22javax+tools%22+compiling+java+file&source=web&ots=XOt0siYe-f&sig=HH27ovuwvJgklIf8omTykUmy-eM
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 :)

Unable to locate existing file from unix using java program
Hi
I have created a file in unix using java program, file.createNewFile();
And when i try to search for the same file using file.exists() it is returning false. Paths are correct. Can anybody help me out.
Thanks & Regards,
PrasanthIn Linux FC5 using JDK1.6, this code File temp = new File(System.getProperty("user.home") + "/abcdefghijklmn");
System.out.println(temp.createNewFile());prints 'true' and the file is created with length zero. -
How to execute a java program by clicking !?!?
Just a click to execute a java program?!!
Like the ".exe" in Windows or "x" permission in Unix ?!?!?!
How can I do that?
And how to set a java program file to display as a personal icon? (My Icon)
:-)Well this is what I do in Windows (I use XP but it works in others):
First you have to make sure all the class files are in the same folder (duh)
Then you copy your java.exe from your jre folder into the folder with all your class files.
Finally, you create a shortcut to java.exe and add your class name to the command line on the shortcut.
Now all you have to do is double click on the shortcut and your program runs. Sure it's not that pretty but it works. -

Calling a function in an EXE file from Java Program
Hi Im having a function which is written in c program.i need to call that function from my java program, if i create a shared library (DLL) for my C code then it works but my requirement is i dont want to create that DLL , like in it would be an executable and my java code should access that function in that C program
I understand the usage od a DLL but the thing is if i convert the exe to a DLL
the server doesnt start at all so what i need is that i dont want to change
that .EXE into a .DLL,let it be an executable. that executable is in running mode
and through my java program i need to call a function in that EXE file.
Is ther any way to do it?Nope, but you have another problem: why can't you separate your server program
into a .dll part and a startup part? Both, when properly linked against each other
should give you an executable file.
kind regards,

However if i give the absolute path of exe file then it doesn't throw an exception but at the same time,it doesn't the do the expected job.
Can somebody throw some light on this?
Thanx in advance
