Hi.
I am passing different kind of text file and calling same function.. Can any one know how to avoid these repeated code.

public static void main(String[] args) throws IOException,NullPointerException
{
              
		MultipleLinearRegrssionModel fex = new MultipleLinearRegrssionModel();
		//Calls Read From File 
                //First ocument
                docsum=1;
		fex.readFromFile("f:/project/document/training/1.txt");
                //Calls compare training corpus and manual summary
                doccom=1;
                fex.strCompare();
		//Calls Stop Words Removing

                fex.testFinalwrite("f:/project/out2final.txt");
	
	}
}

So the above different document calling same function. I am calling one document and for that document some set of function is called.
Next time i am calling different document for the same function.

So my code become very lengthy... can any one suggest to avoid the repeated code. How to call the same function for using different kind document by writing the code only once....

HI ....

Below readfromfile is there.... can you able to tell in what way i can avoid the repeated code....
