There are rules if you actually want help. I mean, someone might do the
whole thing for you, but it's not very likely. You'll have to make an
effort on your own.

Here's a few corrections to your code.

public class Failboat
{

     public static void main( String[] args ) throws Exception
     {
         String originalText = "STRING";
         System.out.println( "\nString is : "+originalText );
         for( int i = 0; i<originalText.length(); i++ )
         {
             char first = originalText.charAt( i );
             System.out.print( first + "=" + (int) first +
                     " / " );
         }
         System.out.print( "\nString Total Length Was
["+originalText.length()+
                 " ]" );
     }
}

Now here's how I'd do it. (I took a few liberties with the formatting.)

public class Failboat
{
     public static void main( String[] args ) throws Exception
     {
         String originalText = "STRING";
         System.out.print( originalText + " = " );
         for( byte b : originalText.getBytes() )
             System.out.print( b + ", " );
         System.out.println( "\nString Total Length Was ["+
                 originalText.length()+"]" );
     }
}

If you're really as stuck as you seem, you should go through the Java
tutorial, especially the basics, and then check out the section of the
tutorial on IO. You're not doing badly, but that was a pretty rough
example you posted. The comment was a nice touch however.

When you do go through the tutorial, remember that you want byte streams
for writing bytes, not character streams. Readers and Writers (like
BufferedReader and InputStreamReader, which you were using) are for
characters, not bytes. DataStreams might also be useful.

You also might check out NetBeans or another IDE, which will help a lot
with importing correctly, removing unused variables, and formatting in
general.
