JAVA Stream流怎么取list<Map>集合的某个属性值的最小数据

Question

JAVA Stream流怎么取list<map>集合的某个属性值的最小数据，我想取出价格最低的数据，就是价格为3999的List<map>
</map></map>

Answer 1

List<Map<String, String>> list = new ArrayList<>();
Map<String, String> m1 = new HashMap<>();
m1.put("价格", "7999");
m1.put("手机", "苹果");
Map<String, String> m2 = new HashMap<>();
m2.put("价格", "3999");
m2.put("手机", "苹果");
list.add(m1);
list.add(m2);

Map<String, String> first = list.stream().min(Comparator.comparingInt(m -> Integer.parseInt(m.get("价格")))).orElse(new HashMap<>());
System.out.println(first);
