Stream流调试视图

Java bean

public class Student {

    private Integer age;

    private String name;

    public Student setAge(Integer age) {
        this.age = age;
        return this;
    }

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

    public Integer getAge() {
        return age;
    }

    public String getName() {
        return name;
    }

    @Override
    public String toString() {
        return "Stuent{" +
                "age=" + age +
                ", name='" + name + '\'' +
                '}';
    }
}

一段实现

    public static void main(String[] args) {
        List<Student> list = Arrays.asList(
                new Student().setAge(18).setName("小一一"),
                new Student().setAge(16).setName("小二二"),
                new Student().setAge(17).setName("小三三"),
                new Student().setAge(21).setName("小四四"),
                new Student().setAge(20).setName("小五五"),
                new Student().setAge(20).setName("小五五")
        );

        list.stream().filter(i -> i.getAge() >= 20)
                .sorted(Comparator.comparing(Student::getAge))
                .map(Student::getName).distinct()
                .forEach(System.out::println);
    }

调试

一般不知道打在什么地方断点
