Esta clase se utiliza para representar una entrada de archivo ZIP. Constructores
    ZipEntry(nombre de cadena):Crea una nueva entrada zip con el nombre especificado. Entrada Zip(ZipEntry e):Crea una nueva entrada zip con campos tomados de la entrada zip especificada.
Métodos:
    Clonar objeto() : Returns a copy of this entry.
      Syntax :  public Object clone()   Overrides:   clone in class Object   Returns:   a clone of this instance.
    Cadena getComentario() : Returns the comment string for the entry or null if none.
      Syntax :  public String getComment()   Returns:   the comment string for the entry or null if none
    largo getCompressedSize() : Returns the size of the compressed entry data or -1 if not known.In the case of a stored entry the compressed size will be the same as the uncompressed size of the entry.
      Syntax :  public long getCompressedSize()   Returns:   the size of the compressed entry data or -1 if not known
    largo getCrc() : Returns the CRC-32 checksum of the uncompressed entry data or -1 if not known.
      Syntax :  public long getCrc()   Returns:   the CRC-32 checksum of the uncompressed entry data or -1 if not known
    byte[] getExtra() : Returns the extra field data for the entry or null if none.
      Syntax :  =public byte[] getExtra()   Returns:   the extra field data for the entry or null if none 
    int getMethod() : Returns the compression method of the entry or -1 if not specified.
      Syntax :  public int getMethod()   Returns:   the compression method of the entry or -1 if not specified
    Cadena getName() : Returns the name of the entry.
      Syntax :  public String getName()   Returns:   the name of the entry 
    largo getSize() : Returns the uncompressed size of the entry data or -1 if not known.
      Syntax :  public long getSize()   Returns:   the uncompressed size of the entry data or -1 if not know
    largo getTime() : Returns the modification time of the entry or -1 if not specified.
      Syntax :  public long getTime()   Returns:   the modification time of the entry or -1 if not specified
    int código hash() : Returns the hash code value for this entry.
      Syntax :  public int hashCode()   Overrides:   hashCode in class Object   Returns:   a hash code value for this object.
    booleano esDirectorio() : Returns true if this is a directory entry. A directory entry is defined to be one whose name ends with a '/'.
      Syntax :  public boolean isDirectory()   Returns:   true if this is a directory entry
    comentario vacío (comentario de cadena): Sets the optional comment string for the entry.ZIP entry comments have maximum length of 0xffff. If the length of the specified comment string is greater than 0xFFFF bytes after encoding only the first 0xFFFF bytes are output to the ZIP file entry.
      Syntax :  public void setComment(String comment)   Parameters:   comment - the comment string
    conjunto vacío Tamaño comprimido (tamaño c largo): Sets the size of the compressed entry data.
      Syntax :  public void setCompressedSize(long csize)   Parameters:   csize - the compressed size to set to
    setCrc vacío (crc largo): Sets the CRC-32 checksum of the uncompressed entry data.
      Syntax :  public void setCrc(long crc)   Parameters:   crc - the CRC-32 value   Throws:   IllegalArgumentException
    void setExtra(byte[] extra): Sets the optional extra field data for the entry.
      Syntax :  public void setExtra(byte[] extra) Parameters: extra - the extra field data bytes   Throws:   IllegalArgumentException
    void setMethod(método int): Sets the compression method for the entry.
      Syntax :  public void setMethod(int method)   Parameters:   method - the compression method either STORED or DEFLATED   Throws:   IllegalArgumentException 
    conjunto vacíoTamaño (tamaño largo): Sets the uncompressed size of the entry data.
      Syntax :  public void setSize(long size)   Parameters:   size - the uncompressed size in bytes   Throws:   IllegalArgumentException 
    void setTime (mucho tiempo): Sets the modification time of the entry.
      Syntax :  public void setTime(long time) Parameters: time - the entry modification time in number of milliseconds since the epoch
    Cadena a Cadena() : Returns a string representation of the ZIP entry.
      Syntax :  public String toString() Overrides: toString in class Object Returns: a string representation of the object.
