i have three fixed but 2nd is dynamic how to do this here.
if( tokens0.equalsIgnoreCase( "CONSTRAINT" ) && tokens2.equalsIgnoreCase( "NOT" ) &&
tokens3.equalsIgnoreCase( "NULL" ) )
// dataLines.append( " -- " );
dataLines.append( "NOT " ).append("NULL ").append(" , ").append(" -- ");

rdr.close(); // close the file
inputstream.close();
// open the file for writing new data to it
FileWriter outputstream=new FileWriter( file );
BufferedWriter writer = new BufferedWriter(outputstream);
// write the new StringBuilder's data back to the file.
writer.write( dataLines.toString(), 0, dataLines.length() );
writer.close(); // close the file
outputstream.close();
} catch( IOException e ) {
System.out.println("Exception"+e);
out put of sql file is now this but it sholud be applied to all.
