Suppose jarFile is the jar/zip file to be extracted. destDir is the path where it will be extracted:
java.util.jar.JarFile jar = new java.util.jar.JarFile(jarFile);java.util.Enumeration enum = jar.entries();while (enum.hasMoreElements()) { java.util.jar.JarEntry file = (java.util.jar.JarEntry) enum.nextElement(); java.io.File f = new java.io.File(destDir + java.io.File.separator + file.getName()); if (file.isDirectory()) { // if its a directory, create it f.mkdir(); continue; } java.io.InputStream is = jar.getInputStream(file); // get the input stream java.io.FileOutputStream fos = new java.io.FileOutputStream(f); while (is.available() > 0) { // write contents of 'is' to 'fos' fos.write(is.read()); } fos.close(); is.close();}
