How to fix Duplicated Code Complexity

Duplicated Code

Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
If you have the same expression in different places: Extract expression to a method
If you have the same method in different sub-classes: Extract method, and pull up field to the parent class
If you have the same code in unrelated classes: Consider extracting the code to a new class, and injecting that class
Complex Class

Tip: Before tackling complexity, make sure that you eliminate any duplication first. This often can reduce the size of classes significantly.
Complex classes like WorkflowDefinition often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use WorkflowDefinition, and based on these observations, apply Extract Interface, too.

/**
 * An overall definition of a workflow
 *
 * The workflow definition has a series of steps to it. Each step has a series of possible transitions
 * that it can take - the first one that meets certain criteria is followed, which could lead to
 * another step.
 *
 * A step is either manual or automatic; an example 'manual' step would be requiring a person to review
 * a document. An automatic step might be to email a group of people, or to publish documents.
 * Basically, a manual step requires the interaction of someone to pick which action to take, an automatic
 * step will automatically determine what to do once it has finished.
