Zip a Directory In Java

Through its java.util.zip package, Java provides you with an easy mechanism to compress/decompress files. Here is a method called zipDir, that shows how to recursively zip a directory structure.

Note that the following method does not add an empty directory to the produced ZIP file.

//the method accepts a String for the directory that should be zipped, and a ZipOutputStream to write the zipped data to.

So the code to invoke the method might be:

 try {     //create a ZipOutputStream to zip the data to     ZipOutputStream zos = new            ZipOutputStream(new FileOutputStream(".\curDir.zip"));     //assuming that there is a directory named inFolder (If there     //isn't create one) in the same directory as the one the code     runs from,     //call the zipDir method     zipDir(".\inFolder", zos);     //close the stream     zos.close(); } catch(Exception e) {     //handle exception } //here is the code for the method public void zipDir(String dir2zip, ZipOutputStream zos) {     try    {         //create a new File object based on the directory we         have to zip File               zipDir = new File(dir2zip);         //get a listing of the directory content         String[] dirList = zipDir.list();         byte[] readBuffer = new byte[2156];         int bytesIn = 0;         //loop through dirList, and zip the files         for(int i=0; i

Now, you should have a curDir.zip in the application's directory. If you view it with a ZIP utility, you'll see that it contains the contents of the directory inFolder.
