例子如下:Maph1=newHashMap();h1.put("12","fdsa");h1.put("123","fdsa");h1.put("124","fdsa");h1.put("125","fdsa");Maph2=newHashMap();h2.put("h12","fdsa");h2.put("h123","fdsa");h2.put("h124","fdsa");h2.put("h125","fdsa");Maph3=newHashMap();h3.put("h312","fdsa");h3.put("h3123","fdsa");h3.put("h3124","fdsa");h3.put("h3125","fdsa");Listlists=newArrayList();lists.add(h1);lists.add(h2);lists.add(h3);想用java8把lists里面的map合并成一個新的map:MaphaNew=newHashMap();//包含了h1,h2,h3的內(nèi)容請問該如何實現(xiàn),謝謝.我自己使用下面的方式實現(xiàn)了一個:privateMapmegerListMap(ListlistsMap){Mapmap=newHashMap();listsMap.forEach(x->{x.forEach((y,z)->{map.put(y,z);});});returnmap;}但想要更簡單的方式.
