I am having a problem in this program....can anybody help me create a BufferedReader out of this maze problem...then i have to create a text document entitled with maze.txt...

well here is my program

import java.io.*;
import java.util.*;

public class Amazing{
public static void main(String[]args){
Scanner console=new Scanner(System.in);

BufferedWriter bw;
int r,c;

try{

I am having a problem in this program....can anybody help me create a BufferedReader out of this maze problem...

Yes.

then i have to create a text document entitled with maze.txt...

Okay.

If you want better answers, you're going to have to ask more detailed questions, particularly the second one, which isn't even a question. Write a concise but detailed paragraph explaining what you need and what you are stuck on. We could guess and probably be correct, but don't make us guess. Tell us.

...thanks for your concern...sorry for I ded not write the whole question correctly...

well here is the question....

Write a program that would allow the user to go out in the maze.The maze is found in maze.txt. if position is "{}" it is open, if "<>" it is backtrack, if "[]" it is exit. Then accept an initial position using command line then lead him the way to go out from the maze.

ex.

maze.txt
10 <><><><><><><>[]<><>
9 <><>{}{}{}{}{}{}<><>
8 <><>{}{}{}<><><><><>
7 <><><><>{}<><><><><>
6 <><>{}{}{}<><><><><>
5 <><>{}<><><><><><><>
4 <><><>{}<><><><><><>
3 <><>{}<><><><><><><>
2 <>{}<><><><><><><><>
1 {}{}{}{}{}{}{}{}{}{}
1 2 3 4 5 6 7 8 9 10


Sample Run:

Enter the position: 1 1

Postion Remarks
1 1 open
2 2 open
3 3 open
4 4 open
5 5 backtrack
4 4 open
5 3 open
.
.
.
.
.
10 8 exit

Congratulations!!!

.... since as you can see I have created a filewriter but then my instructor tell me that it is wrong since she want a bufferedreader to read the maze.txt and would execute the sample run......then if you think that my program is wrong then your free to change it if you can....thanks a lot...

Find out whether you are supposed to have the numbers 1 - 10 in the text file. I tend to doubt it, but I don't know.

Google "java how to read file" and pick a tutorial that you like. Here's a little sample code that can serve as a skeleton. You'll need to replace line 20 and instead have it parse line into a String[] array and stick it into str, but the example shows how to read lines from a file. There's not much to it. Set up a BufferedReader in line 7, read a line in line 18. The tough part is parsing that line and sticking it where you want it.

public static String[][] ReadFile (String filename)
    {
        String str[][] = new String[11][11];
        BufferedReader br = null;
        try
        {
            br = new BufferedReader(new FileReader(filename));
        }
        catch (FileNotFoundException ex)
        {
            System.out.println ("File not found");
            System.exit (1);
        }

        String line;
        try
        {
            while ((line = br.readLine()) != null)
            {
                System.out.println (line);
            }
        }
        catch (IOException ex)
        {
            System.out.println ("IO Exception");
            System.exit (1);
        }

        return str;
    }
}
