The Java 7 Files utility type is useful for working with files:

import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.io.IOException;
import java.util.*;

public class WriteReadUtf8 {
  public static void main(String[] args) throws IOException {
    List lines = Arrays.asList("These", "are", "lines");

    Path textFile = Paths.get("foo.txt");
    Files.write(textFile, lines, StandardCharsets.UTF_8);

    List read = Files.readAllLines(textFile, StandardCharsets.UTF_8);

    System.out.println(lines.equals(read));
  }
}

The Java 8 version allows you to omit the Charset argument - the methods default to UTF-8.
