The similarities in the name are pure marketing, as it was intended to capalitize on the popularity of the object-oriented programming language Java. On the surface, the languages appear to be related. This is because both languages have adopted the majority of the C/C++ programming languages...
The types of the Java programming language are divided into two categories: primitive types (§2.4.1) and reference types (§2.4.6). There is also a special null type, the type of the expression null, which has no name. The null reference is the only possible value of an expression of...

(根据James Gosling(Java之父)编写的《The Java Programming Language》一书的附录中给出了一个Java关键字列表,其中有goto和const,但是这两个是目前无法使用的关键字,因此有些地方将其称之为保留字,其实保留字这个词应该有更广泛的意义,因为熟悉C语言的程序员都知道,在系统类库中使用过的有特殊意义的单词或单词的...

上面的代码片段截取自hotspot/src/share/vm/runtime/arguments.cpp中的Arguments::parse_each_vm_init_arg(const JavaVMInitArgs* args, bool* patch_mod_javabase, Flag::Flags origin) 函数,该函数用来解析一个具体的JVM参数。这段代码的主要功能是解析出需要加载的Agent路径,然后调用add_init_agent函数进行解析...
