Zip文件的操作可以看看java.util.zip

楼上说得对，给你一些具体代码
zipInputStream zin = new zipInputStream(new FileInputStream(zipname));
zipEntry entry;
while ((entry = zin.getNextEntry()) != null )
{
analyze entry;
read the contents of zinfile;
zin.closeEntry();
}
zin.close();

public String readZippedFile(String textFilename, String zipFilename) throws Exception
{
// Open a stream from the entry in the zip file for the file.
// Read the file into a string buffer, then return as a string.
StringBuffer buf;//the intermediary, mutable buffer
BufferedReader breader;//reader for the template files
ZipFile zipFile;//zip file
ZipEntry zipEntry;//entry in zip
InputStream iStream;//input stream of file
try
{
zipFile = new ZipFile(zipFilename);
zipEntry = zipFile.getEntry(textFilename);
iStream = zipFile.getInputStream(zipEntry);
breader = new BufferedReader(new InputStreamReader(iStream));
buf = new StringBuffer();
while(breader.ready())
buf.append((char)breader.read());
breader.close();
}//try
catch(Exception e)
{
throw e;
}//catch
return buf.toString();
}//readZippedFile

不好意思 我是想要在不完全解压的情况下向zip中的某个文件写入数据
