How to read file into a String in Java 8?

Using methods from Files and Paths classes available in Java 8.

package com.farenda.solved;

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

public class JavaSolved {

    // It's good to move such code to reusable methods
    private static String loadFile(String filename) throws IOException {
        // need to pass file encoding
        return new String(Files.readAllBytes(Paths.get(filename)),
                          StandardCharsets.UTF_8);
    }

    public static void main(String[] args) throws IOException {
        if (args.length == 0) {
            System.out.println("Run with a file as a parameter");
        } else {
            System.out.println("Reading from: " + args[0] + " using Java 8");
            System.out.println(loadFile(args[0]));
        }
    }
}

1. Create sample file books.txt with the content:

   "Thinking in Java"
   "Head First Java"
   "Design Patterns: Elements of Reusable Object-Oriented Software"
   "Applying UML and Patterns"
   "Agile Software Development, Principles, Patterns, and Practices"
   

2. Compile the code:

   $> javac src/com/farenda/solved/*.java -d out
   

3. Run with the file as parameter

   $> java -cp out com.farenda.solved.JavaSolved books.txt
