我是c++的新手。现在我正在做一个项目，需要从一个csv文件中读取一个客户列表，然后搜索是否有像“ali”这样的用户名，并打印出有关ali的所有数据。如何搜索“阿里”并打印出所有关于阿里的数据，如客户编号、姓名、电话号码和状态？如果有多个带有“ali”的数据，我又怎么能把它们全部打印出来呢？这是我的密码：

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
import java.util.Iterator;

public class LoadCustomer {
    public static void main(String[] args) throws IOException{
        System.out.println ("Load customer from file");
        ArrayList<Customer> customers = readCustomerFromFile();

        System.out.println (customers);
        System.out.println ();

    private static ArrayList<Customer> readCustomerFromFile() throws IOException{
        ArrayList<Customer> customers = new ArrayList<>();
        List<String> lines = Files.readAllLines(Paths.get("customer.csv"));
        for (int i = 1 ; i < lines.size() ; i++){
            String[] items = lines.get(i).split(",");
            int customerNo = Integer.parseInt(items[0]);
            int phoneNo = Integer.parseInt(items[2]);
            customers.add (new Customer(customerNo,items[1],phoneNo,items[3]));
        }
        return customers;
    }
}

这是我的客户类：（添加getname getter）

public class Customer {
private int customerNo;
private String name;
private int phoneNo;
private String status;
public Customer () {}
public Customer (int customerNo, String name, int phoneNo, String status){
    this.customerNo = customerNo;
    this.name = name;
    this.phoneNo = phoneNo;
    this.status = status;
}
public String getName(){
    return name;
}

public String toString(){
    return customerNo + " " + name + " " + phoneNo + " " + status;
}
public String toCSVString(){
    return customerNo + "," + name + "," + phoneNo + "," + status;
}
}

这是我的数据：

CustomerNo            Name       PhoneNo     Status
    1                  Ali        12345        Normal
    2                  Siti       23456        Normal
    3                  Rone       78910        Normal
    4                  Jean       56789        Normal
    5                  Roby       28573        Normal
    6                  Ali        78532        Normal

非常感谢您的关注。编辑：这是我的程序代码：

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.List;
import java.util.stream.Collectors;

public class FindCustomer {
    public static void main(String[] args) throws IOException{
        System.out.println ("Load customer from file");
        java.util.Map<String, List<Customer>> customers =
        Files.lines(Paths.get("customer.csv"))
                .map(line -> line.split(","))
                .map(field -> new Customer(
                        Integer.parseInt(field[0]), field[1],
                        Integer.parseInt(field[2]), field[3]))
                .collect(Collectors
                        .groupingBy(Customer::getName));
        System.out.println (customers);
    }

}
