You will often see Java programs that have eitherstaticorpublicattributes and methods. In the example above, we created astaticmethod, which means that it can be accessed without creating an object of the class,
Method handles are immutable and have no visible state. Of course, they can be bound to underlying methods or data which exhibit state. With respect to the Java Memory Model, any method handle will behave as if all of its (internal) fields are final variables. This means that any method ...
The meaning of timeout depends on the timeout flag specified in dwFlags. A value of 0 means the session is deleted when the AppLogic calls destroySession( ). pAppName. Name of the application associated with the session. The application name enables the Netscape Application Server to determine...

()to get correct behavior. Otherwise, a change inObjExternalmade by one object will be visible in its clone also. This means that the original object and its clone are not independent—to decouple them, you must overrideclone()so that it clones the objectandObjExternal. Then the original ...
For ordered comparisons using the built-in comparison operators (<, <=, etc.), NaN values have another anomalous situation: a NaN is neither less than, nor greater than, nor equal to any value, including itself. This means the trichotomy of comparison does not hold. To provide the...
FSF还认为“If modules are designed to run linked together in a shared address space, that almost surely means combining them into one program”10（如果两个模块运行时是在共享地址空间连接在一起的，那几乎肯定意味着它们被组合成一个程序）。也即，FSF认为运行时共享地址空间的两个模块大概率存在“复杂...
具体的类加载过程说明和分析,除了参考上面给出的官方链接外,也强烈建议参考《深入理解Java虚拟机》第三版,笔者这里就不赘述了。 2、Class.forName和ClassLoader的差异分析 下面我们来看下具体的源码和API说明,理清差异的原因。 Class.forName(String className)接口源码如下: ...

In all other respects, this method does the same thing as the methodjoinof one argument(§20.20.29). In particular,join(0,``0)means the same thing asjoin(0). If the current thread is interrupted(§20.20.31)by another thread while it is waiting, then the wait is ended and anInterrupt...
