Intent
To specify the outline of an algorithm, letting callers plug in some of the specifics
Overview
The Template Method pattern consists of an abstract class that defines some operation, or set of operations, in terms of abstract suboperations. Users of Template Method implement the abstract template class to provide implementation of the substeps. A template class looks like this code snippet:

| | |
| | public void anOperation(){ |
| | subOperationOne(); |
| | subOperationTwo(); |
| | } |
| | |
| | protected abstract void subOperationOne(); |
| | |
| | protected abstract void subOperationTwo(); |
| | } |
To use it, extend the TemplateExample and implement the abstract suboperations. ...
