Java异常错误I / O

Question

I am getting an error when I try to read my file abc.txt in my D drive. Even I tried format : "D:\\EDU\\java\\abc.txt"

Here's my code :

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();
    }
}

My Error :

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

Make sure the file is actually located in that directory. Right-click and click on Properties to check the path.

If you've done that, change all the \\ to / or \\\\ .

Answer 2

The error is self-explanatory. The file isn't where you have told the application it is. Check your path to make sure that it leads to the file.

Answer 3

1) Change the code as below

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

or

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

//if abc.txt is present in classpath

From InputStream, you have to read the data.

EDIT : Resolve non static error

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