如何正确将数组传递到方法中：找不到符号

Question

我想打印出时间不为0的人的名字，但也许我传递参数的方式不起作用？我输入的条目数为 5

注意： 我知道数组列表，但我不想在这里使用数组列表。如果除了有关数组的事情之外不对程序的其他部分进行任何更改，我将不胜感激。代码不必非常灵活，因此我没有找出数组维度的代码中有多少行，而是手动要求用户输入它

CSV文件中存储的数据（按姓名、年龄、时间顺序）：

Lana,20,6.3
Daniel,30,0
Lucas,29,4.9
Henry,19,8.2
Johnny,59,5.3

代码：

import java.util.*;
import java.io.*;

public class personProgram
{
    public static void main(String[] args)
    {
        int numOfEntries;
        Scanner sc = new Scanner(System.in);

        System.out.println("How many entries are there in the file?");
        numOfEntries = sc.nextInt();        
                
        readFile("PersonStorage.csv", numOfEntries);

        System.out.println("These are the people that do not have their time as 0");
        timeNotZero(persons, numOfEntries)
        
    }

        public static void readFile(String pFileName, int numOfEntries)
    {   
        FileInputStream fileStream = null;
        InputStreamReader rdr;
        BufferedReader bufRdr;
        int lineNum;
        String line;
        
        try
        {
            fileStream = new FileInputStream(pFileName);
            rdr = new InputStreamReader(fileStream);
            bufRdr = new BufferedReader(rdr);
            lineNum = 0;
            line = bufRdr.readLine();
            Person[] persons = new Person[numOfEntries];

            while(line != null)
            {
                processLine(line, lineNum, persons);
                line = bufRdr.readLine();
                lineNum++;
            }
                    fileStream.close();
        }
        catch (IOException errorDetails)
            { 
            if(fileStream != null)
            {
                try
                {
                    fileStream.close();
                }
                catch(IOException ex2)
                { }
            }
            System.out.println("Error in fileProcessing: " + errorDetails.getMessage());
        }
    }

    private static void processLine(String csvRow, int lineNum, Person[] persons)
    {
        String[] data;
        data = csvRow.split(",");
        int lineLength = data.length;
        String name = data[0];
        int age = Integer.parseInt(data[1]);
        double time = Double.parseDouble(data[2]);



        persons[lineNum] = new Person(name, age, time);


    }
    
    private static void timeNotZero(Person[] persons, int numberOfEntries)
    {
        for (int j=0; j < numOfEntries; j++)
        {
                if (persons[j].getTime() != 0)
                { 
                        System.out.println(drivers[j].getName());
        }
    }

}

错误：

error: cannot find symbol
     timeNotZero(persons, numOfEntries)
                 ^
symbol:   variable persons

Answer 1

尝试创建调用函数的 person obj timeNotZero
