Clase Java.util.zip.DeflaterOutputStream en Java
Clase Java.util.zip.DeflaterInputStream en Java Esta clase implementa un filtro de flujo de salida para comprimir datos en el formato de compresión 'deflate'. También se utiliza como base para otros tipos de filtros de compresión como GZIPOutputStream. Constructores y descripción
