Extract Method

Refactoring

The best way to fix this bad code smell is to use Extract Method technique as shown below.

       printOwing() {
               printBanner();
       
               //print details
               System.out.println ("name:	" + _name);
               System.out.println ("amount	" + getOutstanding());
       }

becomes

       void printOwing() {
               printBanner();
               printDetails(getOutstanding());
       }

       void printDetails (double outstanding) {
               System.out.println ("name:	" + _name);
               System.out.println ("amount	" + outstanding);
       }
