一个txt文件中包含：ID、姓氏、名字、父名、地址、余额、城市通话时间、长途通话时间。编写一个Java静态方法读取文件中的信息，并将所有条目，按余额数量排序。只做一个表格

以下是一个简单的Java静态方法，用于从txt文件中读取信息并按余额数量排序：

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class SortByBalance {

    public static void main(String[] args) {
        List<Person> persons = readFromFile("data.txt");
        sortByBalance(persons);

        System.out.println("ID\t姓氏\t名字\t父名\t地址\t余额\t城市通话时间\t长途通话时间");
        for (Person person : persons) {
            System.out.println(person.getId() + "\t" + person.getLastName() + "\t" + person.getFirstName() + "\t" + person.getFatherName() +
                    "\t" + person.getAddress() + "\t" + person.getBalance() + "\t" + person.getCityCallTime() + "\t" + person.getLongDistanceCallTime());
        }
    }

    public static void sortByBalance(List<Person> persons) {
        Collections.sort(persons, new Comparator<Person>() {
            @Override
            public int compare(Person p1, Person p2) {
                if (p1.getBalance() > p2.getBalance()) {
                    return 1;
                } else if (p1.getBalance() < p2.getBalance()) {
                    return -1;
                } else {
                    return 0;
                }
            }
        });
    }

    public static List<Person> readFromFile(String fileName) {
        List<Person> persons = new ArrayList<>();

        try (BufferedReader br = new BufferedReader(new FileReader(fileName))) {
            String line;
            while ((line = br.readLine()) != null) {
                String[] values = line.split("\t");
                int id = Integer.parseInt(values[0]);
                String lastName = values[1];
                String firstName = values[2];
                String fatherName = values[3];
                String address = values[4];
                double balance = Double.parseDouble(values[5]);
                double cityCallTime = Double.parseDouble(values[6]);
                double longDistanceCallTime = Double.parseDouble(values[7]);
                Person person = new Person(id, lastName, firstName, fatherName, address, balance, cityCallTime, longDistanceCallTime);
                persons.add(person);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        return persons;
    }

    private static class Person {
        private int id;
        private String lastName;
        private String firstName;
        private String fatherName;
        private String address;
        private double balance;
        private double cityCallTime;
        private double longDistanceCallTime;

        public Person(int id, String lastName, String firstName, String fatherName, String address, double balance, double cityCallTime, double longDistanceCallTime) {
            this.id = id;
            this.lastName = lastName;
            this.firstName = firstName;
            this.fatherName = fatherName;
            this.address = address;
            this.balance = balance;
            this.cityCallTime = cityCallTime;
            this.longDistanceCallTime = longDistanceCallTime;
        }

        public int getId() {
            return id;
        }

        public String getLastName() {
            return lastName;
        }

        public String getFirstName() {
            return firstName;
        }

        public String getFatherName() {
            return fatherName;
        }

        public String getAddress() {
            return address;
        }

        public double getBalance() {
            return balance;
        }

        public double getCityCallTime() {
            return cityCallTime;
        }

        public double getLongDistanceCallTime() {
            return longDistanceCallTime;
        }
    }
}

这个程序假设数据文件的格式如下：

ID    姓氏    名字    父名    地址    余额    城市通话时间    长途通话时间
1     张      三      李四    北京    100.0  20.5           30.0
2     李      四      王五    上海    50.0   10.0           20.0
3     王      五      赵六    广州    200.0  15.0           25.0

程序将数据文件读取到一个Person列表中，然后按余额数量对列表进行排序。最后，程序将列表输出到控制台。
