Instrumentation is the addition of byte-codes to methods for the purpose of gathering data to be utilized by tools. Since the changes are purely additive, these tools do not modify application state or behavior. Examples of such benign tools include monitoring agents profilers coverage analyzers eve...
在JavaSE 7 Specification中指出,"Note that it is generally necessary to override thehashCodemethod whenever this method(equals) is overridden, so as to maintain the general contract for thehashCodemethod, which states that equal objects must have equal hash codes." 如果你重写了equals()方法,那么一...
Runtime Constant Pool contains constants used in a particular class. The constants can be of types int, float, double, and UTF-8. It also contains references to methods and fields. Method Code is the implementation (opcodes) of all class methods. Attribute and Field Values contain all named...

,不同之处在于可以将其看做一种可以快速访问的带限制的特殊对象,因此有对象的特征(Codes like a class, works like an int),比如: 可以有变量+方法 可以继承接口,例如Point可以从某个Shape接口继承而来 可以通过封装来隐藏内部实现 可以作为泛型使用,可以有泛型参数 有了值类型的支持后,Valhalla的另一个JEP: ...
原理是把这个类会把中的方法会实例化 _bytescodes 中指定的类,我们可以写一个自定义类并在类的初始化函数中加入利用代码,利用条件苛刻,可用于解决不出网利用,需要调用parseObject()方法时,加入Feature.SupportNonPublicField参数。 _bytecodes要进行base64编码 ...
Message Authentication Codes (MAC): like MessageDigests, these also generate hash values, but are first initialized with keys to protect the integrity of messages. KeyFactory: used to convert existing opaque cryptographic keys of type Key into key specifications (transparent representations of the under...

anarchitecture neutralintermediate format designed to transport code efficiently to multiple hardware and software platforms. The interpreted nature of Java technology solves both the binary distribution problem and the version problem; the same Java programming language byte codes will run on any platform...
