Let's dive deep into the underworld of JVM (or as any star wars fan would put it, the dark side of the Force). Let's first understand how JVM treats our beloved string and that will help us understand this new shiny compact string improvement. Let's enter into the magical world of heap. And as a matter of fact, no performance book is complete without a discussion of this mystical world.
