Read .txt file of numbers and draw

Question

Hello.
I am trying to utlize BufferedReader and g.drawline to read numbers from a text file and output to the screen as a "line".
I know I still need a while loop and some error checking, but, am having trouble finishing the more 'basic' portion of the code.
The GUI class is already taken care of. I am just trying to open the file, read, turn to int, produce lines, then close file.
I have commented out some of the code that was provided with the assignment.
Any help would be appreciated.
Thank you.

* DrawingPanel creates a panel used for drawing
* a map
* Numbers stored in text file, usa.txt.
* one number per line.  Read each number
* create a map on screen. GUI provided in a
* 2nd class.
public class DrawingPanel extends JPanel {
     /** Graphics object used for drawing on the panel */                           
     private Graphics g;                  
     /** Tells if it is time to draw */
     private boolean timeToDrawPath;
     /** The filename of the hurricane path */
                              //private String pathFile; 
     private String usa.txt;
     * Creates a new, white DrawingPanel for drawing the maps
     public DrawingPanel() {
          setBackground(Color.white);
          this.timeToDrawPath = false;
                              //this.pathFile = null;
          this.usa.txt = null;
     * This method is called automatically by Java.  There will NEVER
     * be a direct call to paint() anywhere in the code.  Anytime that we
     * need to update what is drawn on the screen, we call repaint().
     * @param grph The graphics window to paint
     public void paint(Graphics grph) {
          g = grph;
          super.paint(g);
          processUSA();
          if (timeToDrawPath){
               drawPath();
     * Reads the USA coastline coordinates from a file and draws the path
     * to the panel
     public void processUSA( ) {
                    //just an example of how to draw a single
                    //line segment from (50,50) to (200,200)
                    //g.drawLine( 300, 50, 200, 200);
     //Insert the while loop here??
     //Include the parse.Int statement
     //Open the file
     String inFile = ("usa.txt");
     FileReader fileReader = new FileReader (inFile);
               //BufferedReader bufReader = newBufferedReader (fileReader);
     BufferedReader bufReader=newBufferedReader (new fileReader ("usa.txt"));
                    //Insert beginning of while loop here????
     //read data from the file
     String str=bufReader.readLine();
     g.drawLine(x1,y1,x2,y2);
     }

Yep, you are right in deciding the positioning of the while loop.
But the folly you are committing is while creating object of BufferedReader ... It is to be created by passing to the constructor, the reference of the FileReader object you have created.
so the line of code shud look like ...
BufferedReader bufReader = new BufferedReader(FileReaderObject);
And then you can go ahead with readLine() as per your requirement in the while loop.
