How to read and write text files since Java SE 7

How to read and write text files in Java? The old way was to use java.io package, since Java SE 7 there's new java.nio package where are classes like Files, Paths and Path:

public static void main(String[] args) throws IOException {
	// write to text file
	ArrayList lines = new ArrayList();
	lines.add("hello world");
	lines.add("hello world 2nd line");
	Path pathToFile = Paths.get("file.txt");
	Files.write(pathToFile, lines);

	// read from text file
	List lines2 = Files.readAllLines(pathToFile);
	for (String line : lines2) {
		System.out.println(line);
	}

}

How to use UTF-8:

Files.write(pathToFile, lines, StandardCharsets.UTF_8);
Files.readAllLines(pathToFile, StandardCharsets.UTF_8);

How to use custom charset:

Files.write(pathToFile, lines, Charset.forName("iso-8859-2"));
Files.readAllLines(pathToFile, Charset.forName("iso-8859-2"));

How to append:

Files.write(pathToFile, lines, StandardCharsets.UTF_8, StandardOpenOption.APPEND);
