Il metodo renameTo() restituisce un valore booleano, vero o falso, che può essere utilizzato per verificare se un file è stato rinominato correttamente. Earlier we saw how to create, read, write, append to a file in java. Questo metodo restituisce una IOException, quindi è necessario utilizzare un blocco try-catch appropriato per gestire l’eccezione. In questo esempio, stiamo utilizzando la classe File per ottenere l’istanza del file, quindi utilizzando il metodo renameTo() abbiamo rinominato il file. Rinominare un file utilizzando il metodo renameTo() in Java In questo articolo, utilizzeremo il metodo renameTo() della classe File, il metodo move() della classe Files e la libreria comune Apache per rinominare il file. Possiamo usare questi metodi per rinominare un file e controllare anche altre operazioni sui file. Rinominare un file in Java è piuttosto semplice poiché Java fornisce diversi metodi integrati nel pacchetto java.io. Rinominare un file utilizzando il metodo renameTo () in Java In questo esempio, stiamo utilizzando la classe File per ottenere l’istanza del file, quindi utilizzando il metodo renameTo () abbiamo rinominato il file. There is another package named java.nio that can be. Questo tutorial introduce come rinominare un file in Java ed elenca alcuni codici di esempio per comprendere ulteriormente l’argomento. The File class of the java.io package is used to perform various operations on files and directories. ![]() Rinominare un file utilizzando la libreria Apache commons in Java.Rinominare un file utilizzando il metodo move() in Java.Rinominare un file utilizzando il metodo renameTo() in Java.rezip( zipfile, "/main-folder", "/versionXY" ) To use the File class, create an object of the class, and specify the filename or directory name: Example Get your own Java Server import java.io.File // Import the File class File myObj new File('filename. Blazing fast since it works only on the central directory and not the files. Java File Handling The File class from the java.io package, allows us to work with files. If you save to a new file or stream, then all of the zip data gets written. Either mv from the command line (you move a file from its current name to its new name) or (usually) right click on it, then choose Rename from a file manager. If you save to the same file, then DotNetZip rewrites only the changed metadata - the entry headers and the central directory records for renamed entries, which saves time with large archives. Rename File Application is written by java with GUI, it should be easy and simple enough to use. You can also add or remove entries, inside the using clause. Zip.Save() // could also save to a new zip file here any changes to the entries are made permanent by Save() entries have been renamed.", renameCount) Zip.Comment = String.Format("This archive has been modified. Using (ZipFile zip = ZipFile.Read(ExistingZipFile))Į.FileName = e.FileName.Replace("/OldDirName/", "/NewDirName/") In DotNetZip, it would look like this: var regex = new Regex("/OldDirName/.*$") But some libraries allow you to rename all the entries that have names that indicate a particular directory, which gives you the result you want. Declaration: Following is the declaration for java.io.File.renameTo (File dest) method: public boolean renameTo (File dest) Parameters: dest The new abstract pathname for the existing abstract pathname. This article is part of the Java Back to Basic series here on Baeldung. In Java we can rename a file using renameTo (newName) method that belongs to the File class. We'll first look into using the Files and Path classes from NIO, then the Java File class, Google Guava, and finally the Apache Commons IO library. As Tom Hawtin's reply states, directories are not first-class entities in the zip file metadata, and as a result, no zip libraries that I know of expose a "rename directory" verb. In this quick tutorial, we're going to look at renaming / moving a File in Java. NET library for zip files that allows renaming of entries. Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists. I know you asked about Java but just for archival purposes I thought I would contribute a note about.
