Giving meaning to the context using the interpreter pattern

The interpreter pattern interprets sequences of characters into desired actions. It was identified early due to its use in SQL statement translation and described in more detail in the GoF’s book.

Motivation

The interpreter pattern defines two types of objects that refer to specific sequences of characters. They are terminal and non-terminal actions or operations that can be performed on the sequence of characters under consideration. These operations represent the computer language that is used and have their own semantics. The syntactic tree of a given sentence – a sequence of characters – is an instance of a compound pattern and is used to evaluate and interpret meaning for the client program.

Finding it in the JDK

The java.base module contains the java.util.regex package with the Pattern class. This class represents the compilation of regular expressions. Specific semantics are applied...
