How to implement a compressed package tool class in java

This article introduces you how to achieve a compressed package tool class in java, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Package com.tools;import java.io.*;import java.util.zip.ZipEntry;import java.util.zip.ZipOutputStream;public class ZipCompress {private String zipFileName; private String sourceFileName; public ZipCompress (String zipFileName, String sourceFileName) {this.zipFileName = zipFileName; this.sourceFileName = sourceFileName;} public void zip () throws RuntimeException {ZipOutputStream zos = null; try {zos = new ZipOutputStream (new FileOutputStream (zipFileName)) Java.io.File sourceFile = new java.io.File (sourceFileName); compress (sourceFile, zos, sourceFile.getName ()); System.out.println ("Compression complete");} catch (Exception e) {throw new RuntimeException ("zip error from ZipCompress", e) } finally {if (zos! = null) {try {zos.close ();} catch (IOException e) {e.printStackTrace () }} / * * Recursive compression method * * @ param sourceFile source file * @ param zos zip output stream * @ param name compressed name * @ throws Exception * / private static void compress (java.io.File sourceFile, ZipOutputStream zos String name) throws Exception {byte [] buf = new byte [2 * 1024] If (sourceFile.isFile ()) {zos.putNextEntry (new ZipEntry (name)); int len; FileInputStream in = new FileInputStream (sourceFile); while ((len = in.read (buf))! =-1) {zos.write (buf, 0, len);} zos.closeEntry (); in.close () } else {java.io.File [] listFiles = sourceFile.listFiles (); if (listFiles = = null | | listFiles.length = = 0) {zos.putNextEntry (new ZipEntry (name + "/")); zos.closeEntry () } else {for (java.io.File file: listFiles) {compress (file, zos, name + "/" + file.getName ());}

Call

/ / filePath generates the address of the compressed package String filePath = prefix address + name + ".zip"; File zip = new File (filePath); zip.deleteOnExit (); / / path folder to be compressed ZipCompress zipCompress = new ZipCompress (filePath, path); try {zipCompress.zip ();} catch (Exception e) {e.printStackTrace () } on how to achieve a compressed package tool class in java to share here, I hope the above content can be of some help to you, can learn more knowledge.
