Chapter 3. Leaning on Java

Being hosted on the JVM, there are several aspects of Clojure that really help to understand about the Java language and platform. The need is not only due to interoperability with Java or understanding its implementation, but also for performance reasons. In certain cases, Clojure may not generate optimized JVM bytecode by default; in some other cases, you may want to go beyond the performance that Clojure data structures offer—you can use the Java alternatives via Clojure to get better performance. This chapter discusses those aspects of Clojure. In this chapter we will discuss:

  • Inspecting Java and bytecode generated from a Clojure source
  • Numerics and primitives
  • Working with arrays
  • Reflection and type hinting
