The first edition in turn constituted a major revision of a previous textbook also written by Hopcroft and Ullman, entitled Formal Languages and Their Relation to Automata. It was published in 1968 and is referred to in the introduction of the 1979 edition.
Automata theory is closely related to formal language theory. In this context, automata are used as finite representations of formal languages that may be infinite. Automata are often classified by the class of formal languages they can recognize, as in the Chomsky hierarchy, which describes a nesting relationship between major classes of automata.
These abstract machines are called automata. Automata comes from the Greek word (Αυτόματα) which means that something is doing something by itself. Automata theory is also closely related to formal language theory, [5] as the automata are often classified by the class of formal languages they are able to recognize. An automaton can be a ...
JFLAP (Java Formal Languages and Automata Package) is interactive educational software written in Java for experimenting with topics in the computer science area of formal languages and automata theory, primarily intended for use at the undergraduate level or as an advanced topic for high school.

Formal languages are used as tools in multiple disciplines. However, formal language theory rarely concerns itself with particular languages (except as examples), but is mainly concerned with the study of various types of formalisms to describe languages. For instance, a language can be given as those strings generated by some formal grammar;
A superset of this language, called the Bach language, [3] is defined as the set of all strings where "a", "b" and "c" (or any other set of three symbols) occurs equally often (aabccb, baabcaccb, etc.) and is also context-sensitive. [4] [5] L can be shown to be a context-sensitive language by constructing a linear bounded automaton which accepts L.
Ullman is the co-recipient (with John Hopcroft) of the 2010 IEEE John von Neumann Medal "For laying the foundations for the fields of automata and language theory and many seminal contributions to theoretical computer science." [6] Ullman, Hopcroft, and Alfred Aho were co-recipients of the 2017 C&C Prize awarded by NEC Corporation. [7]
