java8对list集合中数据进行过滤对集合中的某个对象多个属性排序

java 8中对集合过滤的方法主要是用stream中的filter 进行数据筛选

 public static void main(String[] args) throws Exception{
        ArrayList list = new ArrayList<>();
        for(int i=0;i<100;i++){
            Car car = new Car();
            car.setId(i);
            car.setName("第一条"+i);
            list.add(car);
        }
        List collect = list.stream().filter(e -> e.getId() >= 50&&e.getId()<55).limit(10).collect(Collectors.toList());
        for(Car c:collect){
            System.out.println(c.getId());
        }
    }

也可以了对集合排个序
sorted(Comparator.comparingInt(Car::getId)这个是对id升序 sorted(Comparator.comparingInt(Car::getId).reversed() 这个是对id倒序

 public static void main(String[] args) throws Exception{
        ArrayList list = new ArrayList<>();
        for(int i=0;i<100;i++){
            Car car = new Car();
            car.setId(i);
            car.setName("第一条"+i);
            list.add(car);
        }
        List collect = list.stream().filter(e -> e.getId() >= 50&&e.getId()<55).limit(10).sorted(Comparator.comparingInt(Car::getId).reversed()).collect(Collectors.toList());
        for(Car c:collect){
            System.out.println(c.getId());
        }
    }

对集合中对象的多个属性排序（写多个sorted方法 把优先排序的字段写到最后 优先级依次向前）

public static void main(String[] args) throws Exception{
        ArrayList list = new ArrayList<>();
        list.add(new Car(1,"1",1));
        list.add(new Car(2,"1",1));
        list.add(new Car(3,"1",2));
        list.add(new Car(4,"1",3));
        list.add(new Car(5,"1",1));
        list.add(new Car(6,"1",1));
        list.add(new Car(7,"1",1));
        list.add(new Car(8,"1",3));
        list.add(new Car(9,"1",1));
        list.add(new Car(10,"1",2));
        list.add(new Car(11,"1",1));
        list.add(new Car(12,"1",1));
        list.add(new Car(13,"1",2));
        list.add(new Car(14,"1",2));
        list.add(new Car(15,"1",3));
        List collect = list.stream().filter(e -> e.getId() >= 5&&e.getId()<15).limit(10)
                .sorted(Comparator.comparingInt(Car::getType)).sorted(Comparator.comparingInt(Car::getId).reversed())
                .collect(Collectors.toList());
        for(Car c:collect){
            System.out.println(c.toString());
        }
    }

ublic class Car {
        Integer id;
        String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

结果
50
51
52
53
54
