        public static void main(String args[])
        {

                 {
                        /*Open zip file using, ZipFile(String fileName) constructor of the ZipFile class.This constructor throws IOException for any I/O     error. */


                        ZipFile zipFile = new ZipFile("D:/WebFiles.zip");
 
                       
                        /*To get number of entries (i.e. files and directories) using,int size() method of ZipFile class.*/    

                         
                         int numberOfEntries = zipFile.size();
                         
                         System.out.println("There are ");
                         System.out.print(numberOfEntries);
                         System.out.print(" entries in zip file :");
                         System.out.print(zipFile.getName());  

                         
                        /*close the opened zip file using,void close()method.*/
                         
                         zipFile.close();
       
                 }

                 {
                        System.out.println("Error opening zip file" + ioe);
                 }
