Interpreter Pattern: Given a language, the interpreter pattern can define a representation of its grammar and provide an interpreter at the same time. Clients can use this interpreter to interpret sentences in this language. The interpreter pattern will describe how to interpret these statements using pattern design after having a simple grammar. The language mentioned in the interpreter mode refers to any combination that any interpreter object can interpret. In the interpreter mode, a hierarchical structure of command classes representing grammar needs to be defined, that is, a series of combination rules.
