Reading files with Intellij idea IDE

Question

I am a long time eclipse user and I have started to play around with IntelliJ IDEA.

So from my understanding, a project in IntelliJ is the same as the Eclipse worksp

Answer 1

Instructions

1. Simply right-click on your project directory (the very top folder), then select "New > Directory". Specify a name such as "resources".

1. (optional) Once the folder is generated then right-click "resources" directory, then select "New > Directory" and create an "images" directory.
2. Drag-and-drop your image file into the "images" or "resources" folder you just created. Reference your newly added project file with code File myFile = new File("./resources/images/newfile.txt");

Answer 2

u need to specify complete path inside quotes something like this-->

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

public class Application {
    public static void main(String[] args) throws FileNotFoundException {
        File file = new File("E:\\coding\\ProcessingFiles\\src\\myfile.txt");
        Scanner input = new Scanner(file);
        while (input.hasNextLine()){
            String line = input.nextLine();
            System.out.println(line);
        }
        input.close();

    }
}

Answer 3

1. Run > Edit Configurations
2. Under Configuration tab
   • Working directory: Your file path is relative to this.

Hope this help!

Answer 4

Use the full path of the file instead.

Right click on your file in your project, select "Copy Path", and paste that in to the path of your file.

EDIT: You could also use a relative path for your file. If your file is located in resources/, then you could use the form ./resources/yourfile.txt.

├── resources
│   └── test123.txt
└── src
    ├── MainClass.java

Answer 5

Yesterday I met the same trouble as you.

change the setting of IDEA. run->Edit Configurations -> (select your Application at left window.then set the input content named "Working directory" at right window)

Answer 6

Just move the file directly to the project folder which calls Java (and something under the blue-blurred stripe you made :P).

If that doesn't help, then move the test123.txt file to FirstJavaProgram directory.

You can also change filename to one of these:

1. src/test123.txt

2. FirstJavaProgram/src/test123.txt

I am not sure which one will be fine in your case.
