Error: Java method cannot be applied to given types location - prompter.java

Hi,

When I try to run the project, I'm getting the following error:

Error:(27, 26) java: method readAllLines in class java.nio.file.Files cannot be applied to given types; required: java.nio.file.Path,java.nio.charset.Charset found: java.nio.file.Path reason: actual and formal argument lists differ in length

I've redownloaded the project twice, still the same error.

You need to make sure the Project language level setting for IntelliJ is at least set to 8. I think by default it sets it to 7. In Java 7, java.nio.file.Files.readAllLines required the charset to be passed in as a 2nd parameter.

File -> Project Structure... -> Project Settings -> Project -> Project Language Level = 8 - Lambdas, Type Annotations etc

To remove the Error please make sure you SDK is at least at 8. Go to file-project structure- Project Settings-project and chose at least 8.

I passed a default Charset to readAllLines in Prompter.java and the code worked. I have not fully understood this solution. It'll really be helpful if anyone can explain why this worked. Here's what I did:

private void loadCensoredWords() { mCensoredWords = new HashSet<String>(); Path file = Paths.get("resources", "censored_words.txt"); List<String> words = null; try { words = Files.readAllLines(file, Charset.defaultCharset()); } catch (IOException e) { System.out.println("Couldn't load censored words"); e.printStackTrace(); } mCensoredWords.addAll(words);

I've been getting this error too and have applied the above solution as described by Anand Altekar which fixes it, but I dont understand it. Would be very helpful if someone could explain it, thanks!

Using SDK version 9 and encountered the same problem. Anand's solution worked for me.
