I am working on a MabLibs project that is supposed to iterate through a file, prompt you with anything contained in a <> block and allow you to write over to a new file.

I cannot figure out how to use a Scanner to read a file and turn that into a string so I can use the .length() method to iterate a for loop through the file to find these <> blocks.

I can only use Scanner and can't use array lists, so unfortunately the for loop is the only way I can do this.

Here's the code:

import java.io.*;

import java.util.*;



public class MadLibs {



public static void main(String args)

        throws FileNotFoundException {

            intro();

            madLib();





}



public static void intro() {

    System.out.println("Welcome to the game of Mad Libs.");

    System.out.println("I will ask you to provide various words");

    System.out.println("and phrases to fill in a story.");

    System.out.println("The result will be written to an output file.");

    System.out.println();

}





public static void madLib() throws FileNotFoundException {

    Scanner input = new Scanner(System.in);

    System.out.println("(C)reate mad-lib, (V)iew mad-lib, (Q)uit? ");

    String r = input.next();

    while (!(r.equalsIgnoreCase("c") || r.equalsIgnoreCase("v")

    || r.equalsIgnoreCase("q"))) {

        System.out.println("(C)reate mad-lib, (V)iew mad-lib, (Q)uit? ");

    }

    if (r.equalsIgnoreCase("v")) {

        viewFile();

    }

    else if (r.equalsIgnoreCase("c")) {

        createWord();

    }

}





public static void createWord() throws FileNotFoundException {

    System.out.println("Input file name: ");

    Scanner viewFile = new Scanner(System.in);

    String toRead = viewFile.nextLine();

    File f = new File(toRead);

    while (!f.exists()) {

        System.out.println("File Not Found. Try again: ");

        toRead = viewFile.nextLine();

        f = new File(toRead);

    }

    Scanner input1 = new Scanner(new File(toRead));

    String input2 = input1;

    PrintStream output = new PrintStream(new File(toRead));

    while (input1.hasNext()) {

        String input = input1.next();

        for (int i = 0; i < input2.length(); i++) {

            if (input.startsWith("<") && input.endsWith(">")) {

                String token = input.substring(1, input.length() - 1);

                System.out.println("Please input a: " + token);

                Scanner scan = new Scanner(System.in);

                String replacement = scan.nextLine();

                token = token.replace(token, replacement);

                output.print(token);

            }

        }

    }

}





public static void viewFile() throws FileNotFoundException {

    System.out.println("Input file name: ");

    Scanner viewFile = new Scanner(System.in);

    String toRead = viewFile.nextLine();

    File f = new File(toRead);

    while (!f.exists()) {

        System.out.println("File Not Found. Try again: ");

        toRead = viewFile.nextLine();

        f = new File(toRead);

    }

    Scanner input1 = new Scanner(new File(toRead));

    System.out.println();

    while (input1.hasNextLine()) {

        System.out.println(input1.nextLine());

       }

    }

 }

Any help is greatly appreciated.
