Java- Can't figure out how to access content from a File I've created?

So I have a file called boynames.txt with everything written into it, if I go like this:

   File getNames = new File("boynames.txt"):4

Then I just get a new file called "boynames.txt" , but how do I get access to a file that I have already written inside of it already, but want access to it?

Is this what you're looking for? You can read the file using a Scanner.

Source code:

import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;

class Demo 
{
    public static void main(String[] args) throws FileNotFoundException 
    {
        File f = new File("boynames.txt");
        Scanner names = new Scanner(f);

        while (names.hasNextLine())
            System.out.println(names.nextLine());
    }
}

Output:

demo > javac Demo.java
demo > java Demo

You could use java.io.FileReader:

import java.io.*;
//in a try catch do:
with(BufferedReader r = new BufferedReader(new FileReader("boynames.txt"))) {
  String line = "";
  while ((line = r.readLine()) != null) {
    System.out.println(line);
  }
}
