Design Patterns

Singleton Design Pattern

• This design pattern use in CurrencyConverter class, so that when I use this class in CurrencyConverterController class, I only call getCurrencyInstance() to use it.

Strategy Design Pattern

• This design pattern use for the convert() method which will calculate and return the converted value in different strategy depends on the unit type.

Factory Design Pattern

• This design pattern use in UnitFactory class, this really useful when user change the unit type that user want to convert (for example, change from Length to Volume), UnitConverterController class no need to worry about create the object of that unit because UnitFactory class will choose and create those unit for UnitConverterController class to use.
