Sobre o Livro

Certamente o Java é atualmente uma das linguagens mais usadas e uma das mais populares no mundo, sendo que o seu maior diferencial não está na linguagem e sim na JVM (Máquina virtual Java). Conheça um pouco mais sobre esse motor, seu funcionamento e sua arquitetura para tirar melhor proveito dela em suas aplicações, além de conhecer um pouco sobre a implementação de referência e open source da JVM, o OpenJDK. O conteúdo desse E-book falará sobre:

  • Os registradores da JVM
  • A interface do Java com código nativo, JNI, presente em diversos pontos do JVM, dentre eles, o NIO e Gargabe Collector,
  • O funcionamento básico do Garbage Collector
  • Como compilar o OpenJDK
  • ByteCode e o seu funcionamento
  • E muito mais!
