G1 is planned as the long term replacement for the Concurrent Mark-Sweep Collector (CMS). Comparing G1 with CMS, there are differences that make G1 a better solution. One difference is that G1 is a compacting collector. G1 compacts sufficiently to completely avoid the use of fine-grained ...

I consider the latter "better" than the former. Who wants to call a function with 10 parameters? And more parameters passed between client and server code causes more coupling, which is not good. For example, if it is determined later that a function needs to return one more piece of ...
if you use version 8 and you do not know to which part it is related (the core or a generator), open ithere; if you are sure of the project it is related to, open it in the issues section of the project. Don’t hesitate to ask!
6 Interpreted/Compiled It is an interpreted language. It is a compiled language. 7 Memory management Memory management is done automatically. Java provides Garbage Collector service which automatically deallocates memory once an object is not required. Memory management is to be done manually. 8 virt...

The source file is compiled in the context of an unnamed module. The source file should contain one or more top-level classes, the first of which is taken as the class to be executed. The compiler does not enforce the optional restriction defined at the end of JLS §7.6, that a type ...
在HotSpot中,实现了两种具体的解释器,即模板解释器和C++解释器,它们分别由TemplateInterpreter子模块和CppInterpreter子模块实现。其中,模板解释器正是目前HotSpot的默认解释器。 所以synchroized执行的应该是templateTable_x86_64.cpp的代码,下面把代码摘出来,里面都是汇编,大家观摩: ...
The value of Bytecodes::number_of_codes is 234, which is enough to store all bytecode instructions (including instructions for internal expansion of the virtual machine). Looking back at the Bytecodes::def() function, some attributes of the bytecode are calculated by calling the compute_flag...
