  An instance of class java.lang.Class is created by the Java Virtual Machine for every type it loads. The virtual machine must in some way associate a reference to the Class instance for a type with the typeís data in the method area. 对于每一个被装载的类型(不管是类还是接口),虚拟机都会相应地为它创建一个java.lang.Class类的实例,而 ...
  For each type it loads, a Java Virtual Machine must keep track of whether or not the type was loaded via the primordial class loader or a class loader object. For those types loaded via a class loader object, the virtual machine must store a reference to the class loader object that loaded t ...
  Class variables are shared among all instances of a class and can be accessed even in the absence of any instance. These variables are associated with the class--not with instances of the class--so they are logically part of the class data in the method area. Before a Java Virtual Machine us ...
  For each method declared in the type, the following information must be stored in the method area. As with fields, the order in which the methods are declared by the class or interface must be recorded as well as the data. Hereís the list: 对于类型中声明的每一个方法,方法区中必须保存下面的信息。和字段一样,这些方法在类或者接口中的生命顺序也 ...
  For each field declared in the type, the following information must be stored in the method area. In addition to the information for each field, the order in which the fields are declared by the class or interface must also be recorded. Hereís the list for fields: 对于类型中声明的每一个字段,方法区中必须保存下面的信 ...
      For each type it loads, a Java Virtual Machine must store a constant pool. A constant pool is an ordered set of constants used by the type, including literals (string, integer, and floating point constants) and symbolic references to types, fields, and methods. Entries in the constant po ...
  For each type it loads, a Java Virtual Machine must store the following kinds of information in the method area:  对每个装载的类型,虚拟机都会在方法区中存储以下类型信息: The fully qualified name of the type 这个类型的全限定名 The fully qualified name of the type’s direct superclass (unless the type is an interface or class ...
    方法区(Method Area)与Java堆一样,是各个线程共享的内存区域,它用于存储已被虚拟机加载的类信息、常量、静态变量、即时编译器编译后的代码等数据。虽然Java虚拟机规范把方法区描述为堆的一个逻辑部分,但是它却有 ...
Operations A and B are atomic with respect to each other if, from the perspective of a thread executing A, when another thread executes B, either all of B has executed or none of it has. An atomic operation is one that is atomic with respect to all operations, including itself, that operate on the sa ...
Five Things You Should Know About HTML5 1. It’s not one big thing(它不是单独的大家伙)     You may well ask: “How can I start using HTML5 if older browsers don’t support it?” But the question itself is misleading. HTML5 is not one big thing; it is a collection of individual fea ...
在《JavaScript: The Definitive Guide, 5th Edition》一书的8.8章节其中有一段这样的描述: When you define a nested function, however, the scope chain includes the containing function. This means that nested functions can access all of the arguments and local variables of the containing function. 这句话的主要意思可以理解为: 当你在js中定义一 ...
    楚兵在山南,吾得将为楚王属(怒)[怨]于周。     或谓周君曰:“不如令太子将军整迎吾得于境,而君自郊迎,令天下皆知君之重吾得也。因泄之楚曰:‘周君所以事吾得者器必名曰谋。’楚王必求之,而吾得无效也,王必罪之。” 原文链接:http://xushen87.blog.sohu.com/167372433.html
      苏厉谓周君曰:“败韩、魏,杀犀武,攻赵,取蔺、离石、祁者,皆白起。是攻用兵,又有天命也。今攻梁,梁必破,破则周危,君不若止之。”   谓白起曰:“楚有养由基者,善射;去柳叶者百步而射之,百发百中。左右皆曰‘善’。有一人过曰:‘善射,可教射也矣?’养由基曰:‘人皆[曰]善,子乃曰可教射,子何不代我射之也?’客曰:‘我不能教子支左屈右。夫射柳叶者,百发百中,而不已善息,少焉气[衰]力倦,弓拨矢钩,一发不中,前功尽矣。’今(公)破韩、魏,杀犀武,而北攻赵,取蔺、离石、祁者,公也。公之功甚多。今公又以秦兵出塞,过两周,践韩而以攻梁,一攻而不得,前功尽灭,公不若称病不出也。” 原文链接:ht ...
周君之秦。谓周(最)[冣]曰:“不如誉秦王之孝也,因以(应)[原]为太后养地。秦王、太后必喜,是公有秦也。交善,周君必以为共功;交恶,劝周君入秦者,必有罪矣。”
       雍氏之役,韩征甲与粟于周。周君患之,告苏代。苏代曰:“何患焉?代能为君令韩不征甲与粟于周,又能为君得高都。”周君大悦曰:“子苟能,寡人请以国听。”   苏代遂往见韩相国公中曰:“公不闻楚计乎?昭应谓楚王曰:‘韩氏罢于兵,仓廪空,无以守城,吾收之以饥,不过一月必拔之。’今唯雍氏五月不能拔,是楚病也。楚王始不信瞻应之计矣,今公乃征甲及粟于周,此告楚病也。昭应闻此,必劝楚王以兵守雍氏,雍氏必拔。”公中曰:“善。然吾使者已行矣。”代曰:“公何不以高都与周。”公中怒曰:“吾无征甲与粟于周,亦已多矣。何为与高都?”代曰:“与之高都,则周必折而入于韩,秦闻之必大怒,而焚周之节,不通其使,是公以 ...
