Java 9中的try-with-resources中的有效final变量？

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;

public class EffectivelyFinalTest {
   private static File file = new File("try_resources.txt");
      public static void main(String args[]) throws IOException {
      file.createNewFile();
      BufferedReader bufferedReader = new BufferedReader(new FileReader(file));

      <strong>try</strong>(<strong>bufferedReader</strong>) {
         System.out.println("Can Use Final or Effectively Final in Try with Resources!");
      } finally {
         System.out.println("In finally block");
      }
}
}

<strong>Can Use Final or Effectively Final in Try with Resources!
In finally block</strong>
