问题描述

有人可以帮助我吗?我对编程还很陌生，所以我决定尝试从eclipse来的IDEA，但遇到了一个问题，我从eclipse导入了一个可以正常工作的项目，但是在IDEA中，我无法像在eclipse中一样引用res文件夹无法使用res/image.png我只能执行c:\ ect.有人知道为什么吗?我已将res文件夹设置为资源根.

推荐答案

对于这样的项目结构:

project
|
| -> src
|    |
|    | -> directory
|    |    |
|    |    | -> MyClass.java
|    |    |
|    |    | -> file.txt

使用以下代码在MyClass.java中读取文件

Use the below code to read the file in MyClass.java

import java.io.*;

class MyClass {

    public static void main(String... args) {

        try {

            BufferedReader br = new BufferedReader(new FileReader("src/directory/file.txt"));

            // read your file 

        } catch (FileNotFoundException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

}
