In Java7+ you can use nio

import java.io.IOException;
import java.nio.file.FileStore;
import java.nio.file.FileSystems;

public class ListMountedVolumesWithNio {
   public static void main(String[] args) throws IOException {
      for (FileStore store : FileSystems.getDefault().getFileStores()) {
         long total = store.getTotalSpace() / 1024;
         long used = (store.getTotalSpace() - store.getUnallocatedSpace()) / 1024;
         long avail = store.getUsableSpace() / 1024;
         System.out.format("%-20s %12d %12d %12d%n", store, total, used, avail);
      }
   }
}
