In a Deterministic Finite Automaton (DFA), there can be one or more final (or accept) states. The exact number of final states is determined by the specific language the DFA is designed to recognize. 1. **Single Final State**: A DFA can have just one final state. This is common for recognizing a specific pattern or string.2. **Multiple Final States**: A DFA can also have several final states, which allows it to accept multiple strings or patterns. Each final state corresponds to a different accepted string or condition.3. **No Final States**: While theoretically possible, a DFA with no final states would not accept any strings.The key point is that the number of final states is defined by the requirements of the language being recognized.
