static public boolean unZip(File unZipfileName){
    		int BUFFER=1024;
    		 try {
    	 
    	            String filePath = unZipfileName.getParent()+"/";
    	            ZipFile zipFile = new ZipFile(unZipfileName);
    	            Enumeration emu = zipFile.entries();
    	            int i=0;
    	            while(emu.hasMoreElements()){
    	                ZipEntry entry = (ZipEntry)emu.nextElement();
    	             
    	                if (entry.isDirectory())
    	                {
    	                    new File(filePath + entry.getName()).mkdirs();
    	                    continue;
    	                }
    	                BufferedInputStream bis = new BufferedInputStream(zipFile.getInputStream(entry));
    	                File file = new File(filePath + entry.getName());
    	                File parent = file.getParentFile();
    	                if(parent != null && (!parent.exists())){
    	                    parent.mkdirs();
    	                }
    	                FileOutputStream fos = new FileOutputStream(file);
    	                BufferedOutputStream bos = new BufferedOutputStream(fos,BUFFER);           
    	                
    	                int count;
    	                byte data[] = new byte[BUFFER];
    	                while ((count = bis.read(data, 0, BUFFER)) != -1)
    	                {
    	                    bos.write(data, 0, count);
    	                }
    	                bos.flush();
    	                bos.close();
    	                bis.close();
    	            }
    	            zipFile.close();
    	            return true;
    	        } catch (Exception e) {
    	            e.printStackTrace();
    	            return false;
    	        }
        }

解压GZ文件：

public static boolean unGzFile(File unGzipfileName){
    		String filePath = unGzipfileName.getParent();
    		try {
                GZIPInputStream gis = new GZIPInputStream(new FileInputStream(unGzipfileName));  
                BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(filePath+"/farfetch.xml"));
    			byte[] buffer = new byte[1024 * 8]; 
    			int count = 0; 
    			while((count =gis.read(buffer)) != -1){
    				bos.write(buffer, 0, count);
    			}
    			bos.flush();
    			bos.close();
    			return true;
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    		return false;
    	}
