Some books give immense pleasure to read and you would like to read them again and again, one such book which I higly recommend is Inside Java 2 Virtual Machine.It is a beautiful book which is of great help for the advanced Java developer, offering a detailed guide to the inner workings of today's Java Virtual Machines (JVMs), plus a complete reference to all bytecodes (the "machine code" for the language). It comes with excellent technical detail and demos of JVMs in action on the companion CD-ROM.
