Question

当我尝试在D驱动器中读取文件abc.txt时出错。即使我尝试格式化：“D：\ EDU \ java \ abc.txt”

这是我的代码：

package javapro;

import java.io.FileInputStream;

public class office {

    public static void main (String[] args)throws Exception {
        FileInputStream apple = new FileInputStream ("D:/EDU/java/abc.txt");
        int din;
        while ((din=apple.read())!=-1){
            System.out.println((char)din);
        }
        apple.close();
    }
}

我的错误：

Exception in thread "main" java.io.FileNotFoundException: D:\EDU\java\abc.txt (The system cannot find the file specified)
    at java.io.FileInputStream.open0(Native Method)
    at java.io.FileInputStream.open(Unknown Source)
    at java.io.FileInputStream.<init>(Unknown Source)
    at java.io.FileInputStream.<init>(Unknown Source)
    at javapro.office.main(office.java:8)

Answer 1

确保该文件实际位于该目录中。右键单击并单击“属性”以检查路径。

如果您已完成此操作，请将所有\更改为/或\\。

Answer 2

错误不言自明。该文件不是您告诉应用程序的位置。检查您的路径以确保它指向该文件。

Answer 3

1）更改代码如下

 FileInputStream apple = new FileInputStream ("D:\\EDU\\java\\abc.txt");

或

 InputStream is = getClass().getResourceAsStream("abc.txt");

//if abc.txt is present in classpath

从InputStream，您必须读取数据。

编辑：解决非静态错误

InputStream is = office.class.getClass().getResourceAsStream("abc.txt");

Java异常错误i / o
