将两个ListMap中同下标的map去重合并
public static void main(String[] args) { Map<String,Object> oneMap = new HashMap<>(); oneMap.put("key","001"); oneMap.put("name","张飞"); oneMap.put("age","25"); Map<String,Object> twoMap = new HashMap<>(); twoMap.put("key","001"); twoMap.put("School","桃园"); twoMap.put("age","25"); List<Map<String,Object>> listA = new ArrayList<>(); listA.add(0,oneMap); List<Map<String,Object>> listB = new ArrayList<>(); listB.add(0,twoMap); listA.forEach(a -> { listB.forEach(b -> b.putAll(a)); }); listB.forEach(b -> b.entrySet().forEach(e -> System.out.println(e.getValue()))); }
