使用java.util.zip压缩、解压文件

import java.util.zip.*;  import java.io.*;    public class ZipTest {       public static void main(String[] args) {            if (args.length < 1) {                 System.out.println("请输入参数：javac ZipTest 需压缩的文件名及路径 保存的文件名及路径。(e.g. c:/test.txt)");            } else {                 ZipCompressor compressor = new ZipCompressor();                 boolean isSuccessful= compressor.zipCompress(args, args[args.length - 1]);                 if (isSuccessful) {                      System.out.println("文件压缩成功。");                 } else {                      System.out.println("文件压缩失败。");                 }            }       }  }    class ZipCompressor {       public ZipCompressor() {}         /**@param srcFiles 需压缩的文件路径及文件名       * @param desFile 保存的文件名及路径       * @return  如果压缩成功返回true       */       public boolean zipCompress(String[] srcFiles, String desFile) {            boolean isSuccessful = false;              String[] fileNames = new String[srcFiles.length-1];            for (int i = 0; i < srcFiles.length-1; i++) {                 fileNames[i] = parse(srcFiles[i]);            }              try {                      BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(desFile));                      ZipOutputStream zos = new ZipOutputStream(bos);                      String entryName = null;                      entryName = fileNames[0];                        for (int i = 0; i < fileNames.length; i++) {                           entryName = fileNames[i];                             // 创建Zip条目                           ZipEntry entry = new ZipEntry(entryName);                           zos.putNextEntry(entry);                             BufferedInputStream bis = new BufferedInputStream(new FileInputStream(srcFiles[i]));                             byte[] b = new byte[1024];                             while (bis.read(b, 0, 1024) != -1) {                                zos.write(b, 0, 1024);                           }                           bis.close();                           zos.closeEntry();                      }                        zos.flush();                      zos.close();                      isSuccessful = true;            } catch (IOException e) {            }              return isSuccessful;       }           // 解析文件名       private String parse(String srcFile) {            int location = srcFile.lastIndexOf("/");            String fileName = srcFile.substring(location + 1);            return fileName;       }  }

解压文件：

import java.util.zip.*;  import java.io.*;    public class UnzipTest {       public static void main(String[] args) {            if (args.length != 1) {                 System.out.println("请输入正确参数：java UnzipTest 需解压的文件(e.g. d:/test.zip)");            } else {                 Unzip unzip = new Unzip();                 if (unzip.unzip(args[0])) {                      System.out.println("文件解压成功。");                 } else {                      System.out.println("文件解压失败。");                 }            }           }  }    class Unzip {       public Unzip() {}         /*       * @param srcZipFile 需解压的文件名       * @return  如果解压成功返回true       */       public boolean unzip(String srcZipFile) {            boolean isSuccessful = true;            try {                 BufferedInputStream bis = new BufferedInputStream(new FileInputStream(srcZipFile));                 ZipInputStream zis = new ZipInputStream(bis);                   BufferedOutputStream bos = null;                   //byte[] b = new byte[1024];                 ZipEntry entry = null;                 while ((entry=zis.getNextEntry()) != null) {                      String entryName = entry.getName();                      bos = new BufferedOutputStream(new FileOutputStream("d:/" + entryName));                      int b = 0;                      while ((b = zis.read()) != -1) {                           bos.write(b);                      }                      bos.flush();                      bos.close();                 }                 zis.close();            } catch (IOException e) {                 isSuccessful = false;            }            return isSuccessful;       }  }
