Java中对List中的对象根据某个属性排序（Lamda表达式实现）

public class Person {
	
	private String id;
	
	private String name;
	
	private int age;
	
	public Person(String id, String name, int age) {
		this.id = id;
		this.name = name;
		this.age = age;
	}

	public String getId() {
		return id;
	}

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

	public String getName() {
		return name;
	}

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

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	@Override
	public String toString() {
		return "{id=" + this.id + ", name=" + this.name +"}";
	}

}

实现根据属性age升序排列：

public class MainTest {

	public static void main(String[] args) {
		List<Person> list = Lists.newArrayList(
				new Person("1","abc",1),
				new Person("4","abc",4),
				new Person("2","abc",2),
				new Person("6","abc",6),
				new Person("3","abc",3)
				);
		
		List<Person> result = list.stream().sorted((a, b) -> a.getAge() - b.getAge()).collect(Collectors.toList());
		
		result.stream().forEach(System.out::println);
	}

}

输出排序结果：
