I am using java in order to build a linguistic System for arabic language and i need to use an open source project as a black box inside my System the only problem is that the open source System is in Python so my question how could i use this System in java,
so that i could make this function
String output=applyPythonSystem(String input);
And please don't say Jython (Without explaining How??) i tried to use it but i couldn't find a way to do this function

I have started typing some basic code in java for airline reservation system using eclipse. Now I want to add frontend using html. Is there a way to combine these two codes and make use of only java? I know that javascript,java swing and many more exist but I want to use only java and html and css for frontend and combine with the java code I use. I will be using MYSQL for database
In a java project press Control + N to get the new screen.
Then click new file.
Name it index.html
Now it is done!
If that does not work, download the java file and put it in a VS Code project with the html file
I'm mid-way through a Java project using a '.arpa' file to extract n-gram probabilities.
Ideally I would like to use a '.klm' file (created using the '.arpa' file), similar to:
model = kenlm.LanguageModel('languageModel.klm')
model.score('The dog chased the ball.')
however kenlm for Java isn't supported on windows.
Does anyone know of any alternatives to score sentences?
Thanks.
Resolved by just using a virtual machine to run the project using kenlm
I am displaying a list of files; i.e. xls, doc, pdf, odt etc., in my Java application (Eclipse RCP). When the user clicks on the file, I want to launch the appropriate (according to what the OS thinks) native application, just like it happens in Windows Explorer or the Finder.
And while I am here: It would be nice to also display the same icons that Finder or Explorer use for the different file types.
Is there a library or Eclipse plugin for this?
What you want is java.awt.Desktop:
Desktop.getDesktop().open( file );
I have found an API in Eclipse's SWT now that seems to do the trick:
org.eclipse.swt.program.Program "provides access to facilities for discovering operating system specific aspects of external program launching."
It has methods to find the program for a given file extension, get the program's icon, and even launch the program.
Sounds like you're after the Java Activation Framework ("JAF"). This API lets you determine what files are and what actions you can do on them. Or alternatively the Java Desktop Integration Component ("JDIC"). JDIC allows you to create and no doubt query file associations.
Both projects seem to be in a semi-abandoned state howeer (sigh). But that's par for the course for Sun these days. Only other thing I know of is some Windows specific third party library that's based on JNI called Winpack. It does a bunch of other things too.
You can get the associated icon using the FileSystemView class (Java 1.4+).
Could anyone please tell me how to make a symbolic link (in the same way MKLINK does) and/or remove a symbolic link with Java. I have found solutions that use Java as a wrapper and use a Windows native program to accomplish this, but I really want a pure Java solution. Thank you in advance!
Since Java 7 you can do this easily using the NIO package.
Path target = Paths.get("target");
Path link = Paths.get("link");
Files.createDirectory(target);
Files.createSymbolicLink(link, target);
Do remember that you do need the correct privileges for this. In my unit test I had to run eclipse as an administrator to make it work (same as that I couldn't create a link from a normal cmd.exe)
As far as I know window does not have real symbolic links like Unix-like system do.
However Windows has the following relevant tools:
You can map network drive, i.e. attach drive letter to specified network path. You can definitely do this using WMI. To access WMI from java take a look on tools like JaWin, Jinterop, Jintegra or write WMI script in JScript o VBScript and execute is from Java.
You can use command subst that assigns letter to local file system path. This is the closest approach to Unix soft link.
You can create desktop shortcut. Create one manually and take a look on it. Shortcut is actually regular text file (as far as I remember in INI format). You can easily create one using any language you want including java. This is not soft link but it is clickable.
I am writing/planning to write a program that takes in a java file (or multiple java files), and edits and adds functions/classes/variables and then outputs a new java file (or multiple files).
Is there a C++ or Java library that
Can recognize and output names of classes/functions within a text file
Can recognize and output the names of the input arguments for said classes/functions
Can allow me to insert code at specific lines or within specific functions
Can search for a given variable name/value
Maintains original file formatting
I would prefer not having to manually code something to do the above, so any help would be appreciated.
Thank you in advance!
EDIT: I currently use Eclipse, and am unsure of how to proceed. So to further explain my question:
In eclipse, if I write a program that opens another .java file, How would I go about 'asking' eclipse to output, say, all the class names of the .java file I just opened?
Also I will explain the 'purpose' of this project to further clarify. I want to write a program that can take in any java file, and turn it into a class that can implemented remotely via RMI. To do this I will need to add an execute() function, have the file implement Task and Serializable and add a few variables, etc... Based on my knowledge, doing this in Eclipse would require manual editing of the program, but I would like to completely automate this process.
Thank you, again.
Much of what you need can be found in a modern IDE; and some very good IDEs are open source (eclipse and Intellij IDEA Community Edition for Java). You might look there to see if there are modules that suite your needs.
Looks like you are talking of a tool like eclipse. You might not be looking for a full fledged IDE, but the requirements that you have mentioned are fulfilled by any basic IDE.
If you wish to make one of your own, you can do that using eclipse rich client platform.
All that you would need from Java is the reflection API.
