我可以回答你的问题。以下是从文本文件output.txt读取数据并转换为List<Person>集合的代码：

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        List<Person> people = readPeopleFromFile("output.txt");
        // do something with the List<Person>
    }

    public static List<Person> readPeopleFromFile(String filename) {
        List<Person> people = new ArrayList<>();
        try {
            File file = new File(filename);
            Scanner scanner = new Scanner(file);
            while (scanner.hasNextLine()) {
                String line = scanner.nextLine();
                String[] parts = line.split("\\s+");
                int id = Integer.parseInt(parts[0]);
                String name = parts[1];
                String city = parts[2];
                char gender = parts[3].charAt(0);
                int height = Integer.parseInt(parts[4]);
                int weight = Integer.parseInt(parts[5]);
                int age = Integer.parseInt(parts[6]);

                Person person = new Person(id, name, city, gender, height, weight, age);
                people.add(person);
            }
            scanner.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return people;
    }
}

class Person {
    private int id;
    private String name;
    private String city;
    private char gender;
    private int height;
    private int weight;
    private int age;

    public Person(int id, String name, String city, char gender, int height, int weight, int age) {
        this.id = id;
        this.name = name;
        this.city = city;
        this.gender = gender;
        this.height = height;
        this.weight = weight;
        this.age = age;
    }

    // getters and setters omitted for brevity
}

这段代码会读取名为output.txt的文本文件，将每一行的数据转换为一个Person对象，并将所有Person对象存储在List<Person>集合中。如果你需要使用这个List<Person>集合，你可以在main()方法中调用readPeopleFromFile()方法，然后对List<Person>进行操作。
