I tried this:
InputStream file = Test.class.getResourceAsStream("highScore.txt");
BufferedReader br = new BufferedReader (new InputStreamReader(file));
String text;
text = br.readLine();
while (text!=null) {
System.out.println (text);
}
but I get NullPointerException error.
The resource you're trying to read as an InputStream should exist on your Java Classpath. Otherwise getResourceAsStream() would return null, leading to NullPointerException when you try to create an InputStreamReader out of it. See different-ways-of-loading-a-file-as-an-inputstream on how to read a resource.
Try a simple file instead:
InputStream file = new FileInputStream("highScore.txt");
If you are having problems getting the path right, do this:
System.out.println(new File("highScore.txt").getAbsolutePath());
That will quickly tell you what the "current" directory is. You might find you need to use "../highScore.txt" if you need to go up one directory level, or "/somedir/highScore.txt" if you need to go down, etc.
I find printing the absolute path is the quickest way to resolve these kinds of problems.
FileNotFoundException has nothing to do with that file. Maybe there's somewhere else in your code that you're using a file that isn't there (cos this one is there)You can use this one-liner for file-to-string
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class ScannerSample {
public static void main(String[] args) throws FileNotFoundException {
//Z means: "The end of the input but for the final terminator, if any"
String output = new Scanner(new File("file.txt")).useDelimiter("\\Z").next();
System.out.println("" + output);
}
}
/to the resource name:Test.class.getResourceAsStream("/highScore.txt");
