Answer 1

Compressing Files is extremely easy in Java.
import java.util.zip.ZipOutputStream;
import java.util.zip.ZipEntry;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileInputStream;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.IOException;
* Compresses Files Together
* @author Jegadisan
* @version $Revision$ $Date$
public final class Compressor {
   * The Zip Output Stream to which the Compressed Files will be
   * written to
   * @since 1.1
  private ZipOutputStream _zOS;
   * Creates a Compressor for the Output File Specified
   * @param outputFile The Output File to which the files to be compressed are to be added
   * @throws IOException If any IO Errors are encountered
   * @since 1.1
  public Compressor(File outputFile) throws IOException {
    _zOS = new ZipOutputStream(new FileOutputStream(outputFile));
   * Adds a File to the Compressed File
   * @param f The File to be added
   * @since 1.1
  public void addFile(String entryName, File f) throws IOException {
    _zOS.putNewEntry(new ZipEntry(entryName));
    BufferedInputStream bIS = new BufferedInputStream(new FileInputStream(f));
    bOS = new BufferedOutputStream(_zOS);
    byte[] buffer = new byte[2048];
    int bytesRead = 0;
    while ((bytesRead = bIS.read(buffer,0,buffer.length) != -1) {
      bOS.write(buffer, 0, bytesRead);
    bOS.flush();
    bIS.close();
    _zOS.closeEntry();
   * Closes the Compressed File.
   * @throws IOException If any IO errors are encountered
   * @since 1.1
  public void close() throws IOException {
    _zOS.close();
}Of course ,the code is not complete. This compressor is only capable of adding Files to the compressed File. Directories can't be added. Test the code before you use it. It should work, but I dun have a compiler on this Machine, and I am too lazy to download one
