Answer 1

public boolean zip( String entryname, byte[] data ) {
boolean ret = false;        if( ( entryname != null ) && ( data != null ) && ( data.length != 0 ) ) {
            try {
                File zipFile = new File( this.fullname );
                ZipOutputStream zipoutStream = new ZipOutputStream( new FileOutputStream( zipFile ) );
                ZipEntry target = new ZipEntry( entryname );
                zipoutStream.putNextEntry( target );
                zipoutStream.write( data );
                zipoutStream.closeEntry();
                zipoutStream.close();
                ret = true;
            } catch( IOException e ) {
                System.out.println( "Zipper.zip( byte[] data ):" + e.getMessage() );
            }
        } return ret;
    }
