Java how to achieve ZIP compression and decompression, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

The program realizes ZIP compression. Divided into two parts: compression (compression) and decompression (decompression)

General functions include the use of polymorphic, recursive and other JAVA core technologies, which can compress and decompress a single file and any cascading folder. You need to customize the source input path and the target output path in your code.

Package com.han; import java.io.*; import java.util.zip.*; / * program implements ZIP compression. It is divided into two parts: * compression and decompression *

* rough features include the use of polymorphic, recursive and other JAVA core technologies, which can compress and decompress individual files and arbitrary cascading folders. * you need to customize the source input path and destination output path in the code. *

* in this code, the compressed part is implemented; the decompressed part can be found in the decompression section of this package. * @ author HAN * * / public class CopyOfMyZipCompressing {private int kryp1; / / define the recursive number variable public CopyOfMyZipCompressing () {/ / TODO Auto-generated constructor stub} public static void main (String [] args) {/ / TODO Auto-generated method stub long startTime=System.currentTimeMillis (); CopyOfMyZipCompressing book=new CopyOfMyZipCompressing () Try {book.zip ("C:\\ Users\\ HAN\\ Desktop\\ stock\\ SpectreCompressed.zip", / / custom zip output path new File ("C:\\ Users\\ HAN\\ Desktop\\ CombinedSpectres.txt")) / / Custom source input path, that is, the file or folder to be compressed} catch (Exception e) {/ / TODO Auto-generated catch block e.printStackTrace ();} long endTime=System.currentTimeMillis (); System.out.println ("time spent:" + (endTime-startTime) + "ms") } private void zip (String zipFileName, File inputFile) throws Exception {System.out.println ("compressing..."); ZipOutputStream out=new ZipOutputStream (new FileOutputStream (zipFileName)); BufferedOutputStream bo=new BufferedOutputStream (out); zip (out,inputFile, "/" + inputFile.getName (), bo); bo.close (); out.close () / / output stream closes System.out.println ("Compression complete");} private void zip (ZipOutputStream out, File f, String base, BufferedOutputStream bo) throws Exception {/ / method overloads if (f.isDirectory ()) {File [] fl=f.listFiles (); for (int iCompression 0)
