help with file reader

[jason27131]

how do i actually run file reader?
i know i have to create a new object, but what do i
enter as the argument? This is the code.

Code:
import java.io.*;


public class FileAccess {


public static void displayFile(String f) throws IOException {
FileReader fr = new FileReader(f);
BufferedReader br = new BufferedReader(fr);

String line = br.readLine();

while (line != null) {


System.out.println(line);


line = br.readLine();
}

br.close();
fr.close();
}


public static void writeToFile(String outfile, String s) throws IOException {
FileOutputStream fs = new FileOutputStream(outfile);
PrintStream p = new PrintStream(fs);


p.println(s);

p.close();
fs.close();
}
}

ty very much

import java.io.*;

public class FileAccessRx {
    public static void displayFile(String f) throws IOException {
        FileReader fr = new FileReader(f); 
        BufferedReader br = new BufferedReader(fr); 

        String line = br.readLine();
        while (line != null) {
            System.out.println(line);
            line = br.readLine();
        }
        br.close();
        fr.close();
    } 

    public static void writeToFile(String outfile, String s) throws IOException {
        FileOutputStream fs = new FileOutputStream(outfile);
        PrintStream p = new PrintStream(fs);
        p.println(s);
        p.close();
        fs.close();
    }

    public static void main(String[] args) throws IOException {
        // Your methods have the static modifier so you can
        // access/call them like this:
        FileAccessRx.displayFile("FileAccessRx.java");
        FileAccessRx.writeToFile("staticAccess.txt", "Hello World");

        // Or if you like you can use a reference to the class
        // to access/call them.
        FileAccessRx fileAccess = new FileAccessRx();
        String s = "Calling a static method using an instance variable.";
        fileAccess.writeToFile("instanceAccess.txt", s);
    }
