Java中的FileReader找不到该文件

Question

我试图读取一个纯文本文件，但不知何故FileReader找不到我的文本文件。我用getAbsolutefile()检查了目录，/Users/djhanz/IdeaProjects/datalab2/pg174.txt是文件的确切位置。我试了datlab2/pg174.txt尽我所能。 这是我的密码

public class Program1 {

    public static void main(String[] args) {
        System.out.println(new File("pg174.txt").getAbsoluteFile());
        Scanner testScanner = new Scanner(new BufferedReader(new FileReader("/Users/djhanz/IdeaProjects/datalab2/pg174.txt")));
        while (testScanner.hasNextLine())
        {
            System.out.println(testScanner.nextLine());
        }

    }


}

文本文件位于名为datalab的同一项目目录下。 有人能告诉我吗

使用Scanner testScanner = new Scanner(new BufferedReader(new FileReader("/pg174.txt")));

FileReader("/pg174.txt")而不是FileReader("pg174.txt")

package com.example.demo;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.util.Scanner;

public class Program1 {

    public static void main(String[] args) throws FileNotFoundException {
        System.out.println(new File("pg174.txt").getPath());
        System.out.println(new File("pg174.txt").getAbsoluteFile());
        System.out.println(new File("pg174.txt").getAbsolutePath());
        Scanner testScanner = new Scanner(new BufferedReader(new FileReader("/pg174.txt")));
        while (testScanner.hasNextLine()) {
            System.out.println(testScanner.nextLine());
       }
    }
}

输出：
