assertThat(Objects.equal(a, b)).isTrue(); 1 2 3 4 尽管它没有被标记为deprecated,但是这个方法的JavaDoc说它应该被视为deprecated,因为java7提供了Objects#equals方法。 8.2 Comparison方法 现在,Guava库没有提供一个方法来比较两个对象(我们将在下一节中看到如何实现这一点),但它确实提供了比较原始值的方法。

三.比较 当需要排序的集合或数组不是单纯的数字型时,通常可以使用Comparator或Comparable,以简单的方式实现对象排序或自定义排序。 A comparison function, which imposes a total ordering on some collection of objects. Comparators can be passed to a sort method (such as Collections.sort or Arrays.sort) to...
> c); /** * 清除容器中的所有元素,方法返回后,容器将为空 */ void clear(); // Comparison and hashing /** * 判断当前集合是否和参数 o 等价 */ boolean equals(Object o); /** * 返回该集合对象的 hashCode */ int hashCode(); } 可以看到,Collection 接口提供了线性类型和集合类型的集合的...

In this case there are multiple forms of sorting, we can write different sorting based on different attributes of objects to be sorted, e.g. We can sort players by age, by ranking, and by namewithout change our Player class, to do that we use other class for Age Comparison and other ...
new RandomAccessSubList<>(this, fromIndex, toIndex) : new SubList<>(this, fromIndex, toIndex)); } // Comparison and hashing /** * 判断当前列表和参数所指向的对象是否等价,如果参数 o 所指向的对象也是 List 对象, * 那么通过判断两个列表的长度是否相等和所有元素是否等价(通过 equals 方法)来决定。

Therefore, every class should override theequals(andhashCode) method of theObjectclass and specify the equivalence relation on objects, such that it evaluates the comparison of values in the object irrespective of whether two objects refer to the same instance or not.
