3.CAS(Compare-and-Swap)操作 为了进一步提高并发性能,ConcurrentHashMap在插入元素、更新数据时,采用了CAS操作。这是一个原子性操作,能够确保在多个线程同时访问相同元素时,只有一个线程能够成功更新数据。 具体来说,ConcurrentHashMap在进行插入、更新时,会通过CAS检查当前值是否被其他线程修改过。如果没有被修改,它会...
The runtime library now needs an extra file refmap.c. Release 0.5.1 fixes a buffer overrun in the JSON printer and improves the portable libraries <stdalign.h> compatibility with C++ and the embedded newlib standard library. JSON printing and parsing has been made more consistent to help ...
@files:一个或多个 包含待编译.java文件列表 的文件。 注:当要编译的.java文件较少,直接在javac命令后接上源文件列表即可,例如:javac SourceFile1.java SourceFile2.java当要编译的Java文件较多时可以使用*.java通配,也可以将源文件名列在一个文件中(任意后缀均可,例如:sourcefiles.anything),然后在 javac ...
