And how much memory will Java 9 strings save in Bulgaria? What is the maximum length of a constant string? And a dynamic string? How much faster is the new StringBuilder().append("Hello ").append(name).toString() than "Hello " + name? What are intrinsics, and how do they relate to strings? Are strings really immutable? How can you efficiently create substrings? You’ll get answers to these and many more questions in this session.
