ZipOutputStream out=new ZipOutputStream(new FileOutputStream(zipFileName));
for(int i=0;i<fileList.size();i++){
String filename = (String)fileList.get(i);
File file = new File(filename);
zip(out,file);
}
out.close();
下载的如下：
private int blockSize=65000;
File file = new File(sourceFilePathName);
FileInputStream fileIn = new FileInputStream(file);
int readBytes = 0;
readBytes = fileIn.read(b, 0, blockSize);
totalRead += readBytes;
out.write(b, 0, readBytes);
代码大致如此，请参考。
