Java code to save a variable to a a text file

Question

I need code to write a single line like Aidan Dowling to a text file. My code so far is:

package battleships.startmenu;
import java.util.Scanner;
public class Startmenu {

    public static void main(String[] args) {
        System.out.print("Hello! Please enter your first name: ");
        Scanner reader = new Scanner(System.in);
        String a;
        String b;
        a=reader.next();
        System.out.print("Enter your second name: ");
        b=reader.next();

        System.out.println("Hello " + a+ " " + b + "!");
        System.out.println("\tHello");
        String name;
        name = a + b;
    }
}

I want the variable name to print out to a document called name.txt

What did you try? What is the relation between your question and the code you pasted? — Happy, Jan 26 '14 at 21:14
Try looking at the [Java Tutorials](http://docs.oracle.com/javase/tutorial/essential/io/fileOps.html). — Keppil, Jan 26 '14 at 21:14

Use a `PrintWriter`. It works a lot like `System.out` but it writes to a file. — Andrew Gies, Jan 26 '14 at 21:14
The class for writing a file is aptly named `FileWriter`. http://docs.oracle.com/javase/7/docs/api/java/io/FileWriter.html — Chris Martin, Jan 26 '14 at 21:14
Why is this question voted down? The other one was way too complicated! — user3127013, Jan 26 '14 at 21:19

create a writer

PrintWriter writer = new PrintWriter("name.txt", "UTF-8");

write a line

writer.println(name);

close the writer

writer.close();

Writing name to name.txt:

Files.write(Paths.get("name.txt"), Arrays.asList(name), StandardCharsets.UTF_8);
