NettetPuede envolver el mapa en un Mapa de Colecciones sincronizadas para obtener un mapa de hash sincronizado que mantenga el orden de inserción. Esto no es tan eficiente como un ConcurrentHashMap (y no implementa los métodos de interfaz extra de ConcurrentMap), pero sí le ofrece el comportamiento (algo) seguro de subprocesos. NettetAnswer #1 97.4 %. You can wrap the map in a Collections.synchronizedMap to get a synchronized hashmap that maintains insertion order. This is not as efficient as a ConcurrentHashMap (and doesn't implement the extra interface methods of ConcurrentMap) but it does get you the (somewhat) thread safe behavior.
