bA textbook that uses a hands-on approach to teach principles of programming languages, with Java as the implementation language.b pThis introductory textbook teaches the principles of programming languages by using an experiential learning style, in which students learn about language features by realizing those features in a pedagogical compiler. Students use Java--the most commonly used programming language in the first two years of the computer science curriculum--as the implementation language throughout. The book also discusses a range of emerging topics in programming languages missing from existing textbooks, including concurrency, Big Data, and event-driven programming. The goal is to prepare students to design, implement, analyze, and understand both domain-specific and general-purpose programming languages. pThe book first develops basic concepts in languages, including means of computation using primitive values, means of combination such as variable definition and function
