Template pattern uml

This design pattern is used popularly in framework development. This helps to avoid code duplication also. Source: Wikipedia AbstractClass contains the templateMethod which should be made final so that it cannot be overridden. This template method makes use of other operations available in order to run the algorithm but is decoupled for the actual implementation of these methods.

All operations used by this template method are made abstract, so their implementation is deferred to subclasses. ConcreteClass implements all the operations required by the templateMethod that were defined as abstract in the parent class. There can be many different ConcreteClasses. The above example deals with order processing flow. The OrderProcessTemplate class is an abstract class containing the algorithm skeleton.

As shown on the note, processOrder is the method that contains the process steps. We have two subclasses NetOrder and StoreOrder which have the same order processing steps. So the overall algorithm used to process an order is defined in the base class and used by the subclasses. But the way individual operations are performed varies depending on the subclass. Control at what points subclassing is allowed. The biggest advantage to using SmartDraw are the templates and examples included.

Javatpoint Services JavaTpoint offers too many high quality services. Benefits: It is very common technique for reusing the code. This is only the main benefit of it. Usage: It is used when the common behavior among sub-classes should be moved to a single common class by avoiding the duplication.

Step 2: Create a Chess class that will extend Game abstract class for giving the definition to its method. Step 3: Create a Soccer class that will extend Game abstract class for giving the definition to its method.
