    Default Can I change attributedstring into string?

    I have a maze and I want to change color for the path of the maze. I know that you can add color to a String with addAttribute, but then I need to place the String back into the String array in order to printout the maze. How can I change attributeString into String or is there another way to add color to a String.
    import java.awt.*;
    import java.text.*;
    import javax.swing.*;
    import java.awt.font.*;
    public class Maze extends JPanel
    {
       private final String TRIED = "0";
       private final String PATH = "-";
       private final String SPACE = " ";
     
     
       private String[][] grid = 
                      { {" "," ","*","*","*","*","*","*","*"},
    			      {"*"," "," "," "," "," ","*"," ","*"},
    			      {"*"," ","*","*","*","*","*"," ","*"},
    			      {"*"," ","*"," ","*"," "," "," ","*"},
    			      {"*"," ","*"," ","*","*","*"," ","*"},
    			      {"*"," "," "," ","*"," "," "," ","*"},
    			      {"*"," ","*"," ","*"," ","*"," ","*"},
    			      {"*"," "," "," "," "," ","*"," ","*"},
    			      {"*","*","*","*","*","*","*"," "," "}};
     
     
     
     
       public boolean traverse (int row, int column, Graphics g) 
       {
           AttributedString attributedString = new AttributedString(PATH);
           attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red);
     
           boolean done = false;
          if (valid (row, column))
          {
             grid[row][column] = TRIED;  
             if (row == grid.length-1 && column == grid[0].length-1)
                done = true;  
             else
             {
                done = traverse (row+1, column, g);     
                if (!done)
                   done = traverse (row, column+1,  g);  
                if (!done)
                   done = traverse (row-1, column, g);  
                if (!done)
                   done = traverse (row, column-1, g);  
             }
             if (done) 
                grid[row][column] = PATH;
          } 
          return done;
       }
       private boolean valid (int row, int column)
       {
          boolean result = false;
     
          if (row >= 0 && row < grid.length &&
              column >= 0 && column < grid[row].length)
    	  if (grid[row][column] == SPACE)
    	      result = true;
     
          return result;
       }
       public String toString ()
       {
          String result = "\n";
     
          for (int row=0; row < grid.length; row++)
          {
             for (int column=0; column < grid[row].length; column++)
                result += grid[row][column] + "";
     
    	     result += "\n";
          }
     
          return result;
       }
    }
