JFlex

JFlex is an open-source lexical analyzer generator for Java, designed to create fast and efficient scanners based on deterministic finite automata. It processes input specifications containing regular expressions to generate lexer code that tokenizes text streams, serving as a critical front-end component in compiler construction and text processing applications. The tool is widely integrated with parser generators like CUP, ANTLR, and BYacc/J to facilitate robust language parsing workflows.
