Why do I get the error "File cannot be resolved to a type"?

Question

Here's part of my code

try{

    BufferedReader in= new BufferedReader(new InputStreamReader(System.in));

    while ((line= in.readLine())!="exit"){

    System.out.println("Enter command");
    line=in.readLine();
    Command currentCommand=new Command(line);



    File currentFile= new File(currentCommand.getLsPath());

The method currentCommand.getLsPath() returns a string, which is mendatory for the File Constracture, and still I get this error: File cannot be resolved to a type

What is the problem?

Chances are you've just missed:

import java.io.File;

from the top of your source file.

You could use

 import java.io.*;

I typically use single-type imports.

You need to include either

import java.io.File;

or

import java.io.*;

at the top of your source file.

Jon Skeet beat me by 12 seconds. There is no dishonor in that :) – Ernest Friedman-Hill May 13 '11 at 19:47
So wierd, so why It does not notify me about that as any other package? – Unknown user May 13 '11 at 19:48
You should need to import `BufferedReader` and `InputStreamReader`. The `Command` class may be local to your application, and the `System` class is automatically imported, like everything else in the `java.lang` package. – Ernest Friedman-Hill May 13 '11 at 19:49
These I imported, but when I forgot to do that, I got a notifaction suggesting me ti import them, unlike this one. – Unknown user May 13 '11 at 19:51
@Unknown user: When I tried with `BufferedReader` I got exactly the same error as for `File`. – Jon Skeet May 13 '11 at 19:54

I received this error once, even though I had already imported java.io.File. I think it was some weird, temporary Eclsipse glitch. When I made other changes to the code, then saved it again, the error resolved itself.

You most likely forgot to import java.io.File but essentially the compiler is telling you it can't find the "File" class.

See this java error page specific to "File cannot be resovled to a type" for more info.

i also got that error and by giving try catch block just before creating object of FileReader , FileWriter not before creating a variable of type FileReader or FileWriter could resolve that issue and just make sure to close the resource .

I don't think so. The solution for the type 'File' not being defined is to define it (via an import statement). – Arfur Narf Jun 20 '23 at 00:22
