4.2. Requires Static Sometimes we write code that references another module, but that users of our library will never want to use. 有的时候会出现代码引用了另一个模块但是永远没有使用。 For instance, we might write a utility function that pretty-prints our internal state when another logging mod...

While the Java Compiler is strict in its compile-time static checking, the language and run-time system aredynamicin their linking stages. Classes are linked only as needed. New code modules can be linked in on demand from a variety of sources, even from sources across a network. In the ...
static class Inner { void test() { syso(x); } } } 如果问静态内部类能否访问外部类的成员这个问题,该如何回答: 答题时,也要能察言观色,揣摩提问者的心思,显然人家希望你说的是静态内部类不能访问外部类的成员,但你一上来就顶牛,这不好,要先顺着人家,让人家满意,然后再说特殊情况,让人家吃惊。
This document describes what you need to do in order to integrate your provider into Java SE so that algorithms and other services can be found when Java Security API clients request them.
Now, moving on to themainmethod, it is seen that the static function is directly accessible with the class name. We do not have to instantiate theInnerClassobject. Similarly, when we try to access the non-static functionfunction1with the class name, a compile-time error is populated. If ...
A factory method is a static method that returns an instance of a class. The engine classes use the framework provider selection mechanism described above to obtain the actual backing implementation (SPI), and then creates the actual engine object. Each instance of the engine class encapsulates (...
