Write ZipEntry Data To String

Issue

I have retrieved a zip entry from a zip file like so.

InputStream input = params[0];
ZipInputStream zis = new ZipInputStream(input);

ZipEntry entry;
try {
    while ((entry = zis.getNextEntry())!= null) {

    }
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

This works fine and its getting my ZipEntry no problem.

My Question

How can I get the contents of these ZipEntries into a String as they are xml and csv files.

Solution

you have to read from the ZipInputStream:

StringBuilder s = new StringBuilder();
byte[] buffer = new byte[1024];
int read = 0;
ZipEntry entry;
while ((entry = zis.getNextEntry())!= null) {
      while ((read = zis.read(buffer, 0, 1024)) >= 0) {
           s.append(new String(buffer, 0, read));
      }
}

When you exit from the inner while save the StringBuilder content, and reset it.
