(usually involves the properties of your object in the operations, that's why generally you have to override the method from the original in object class) so than number is the result and is unique (we hope) The
This allows you to detect changes on properties of individual object(s). This is not the case for Set/Collection because those are not ordered containers. Here it's impossible to detect changes between the same objects on left/right side. Normally in JAVA hashCode() method is used to ...

您应该只调用capture在verify调用期间代表一个参数，然后使用getValue或getValues检索捕获的值。

function createHashCode (object){ return obj.someUniqueKey; // Just an example }; let dict = {}; dict[key(obj1)] = obj1; dict[key(obj2)] = obj2; There is, however, the Map abstraction in JavaScript. let map = new Map(); let obj1 = { value: 1 } let obj2 = { value: ...
@ToString generates an implementation for the toString() method which consists of a “pretty print” version of the object containing the class name and each field and its value. @EqualsAndHashCode generates implementations of the equals and hashCode methods that, by default, uses all non-static...
对于Java Bean类的两个对象x和y,equals方法的实现保证如下等式成立 x.compareTo(y) ==0时,x.equals(y)为true 修改方法很简单,本项目使用了Lombok,因此为Java Bean类实现equals方法并不需要写代码。同时Lombok还很贴心的生成了hashCode方法,这又避免了另外一个FindBugs问题,即实现equals方法时,需要同步实现hashCode...
2.1 如果java版本大于7并且option是NioChannelOption 调用jdk对channel设置option 2.2 jdk版本不支持或者设置的是OIO类型 手动使用if else完成对channel中的option的设置,如果遇到了if else中不存在的option类型,需要手动在if else上添加判断分支。 总结:下面两个代码的区别是,一个通过if else的方式手动设置channel的optio...
