Question

I want to read some data for my app. Here my code:

 URL url = Myclass.class.getResource("/data/file.txt"); //Myclass is my class name
    File file = new File(url.toString());  //maybe I met error here. 
//File Constructor just receive String object, I don't know how to convert
    FileInputStream reader = new FileIputStream(file);

I don’t know how to change url to File to read it. Please tell me how to solve.

Thanks 🙂

You can’t read a resource as if it were a file. The following syntax should work:

InputStream resource = MyClass.class.getResourceAsStream("/data/file.txt");

To avoid relative / absolute path issues, you can also use:

InputStream resource = MyClass.class.getClassLoader().getResourceAsStream("/data/file.txt");
