After getting introduced to Design Patterns we have so far examined the following patterns:

• Adapter Pattern
• Facade pattern
• Composite Pattern
• Bridge Pattern
• Singleton Pattern
• Observer Pattern
• Proxy Pattern
• Chain of Responsibility Pattern
• Flyweight Pattern
• Builder Pattern
• Factory Method Pattern
• Abstract Factory Design Pattern
• Prototype Design Pattern
• Memento Design Pattern
• Template Design Pattern
• State Design Pattern
• Strategy Design Pattern
• Command Design Pattern

Now, we will now get to know the Interpreter Design Pattern.

The Interpreter Design Pattern is a heavy-duty pattern. It’s all about putting together your own programming language, or handling an existing one, by creating an interpreter for that language. Given a language, we can define a representation for its grammar along with an interpreter that uses the representation to interpret sentences in the language.

Via a real life example, you will learn how and when the Interpreter design pattern should be used and how to structure your code in order to implement it. You will see how it can lead to elegant solutions to code problems.
