Bob 大叔前天更新了博客 Classes vs. Data Structures , 对 面向对象中的 Object 与面向过程中的 Data Structure 作了一番比较，很有意思。 两者在三方面存在相对关系：Classes make functions visible while keeping data implied. （Classes 中函数是显性的而数据是隐含的，Data Structure 中数据是显性的而函数是隐含的）Classes make it easy to add types but hard to add （Classes 易增加类型，不易增加函数; Data Structure 易增加函数而不易增加类型）Data Structures expose callers to recompilation and Classes isolate callers from recompilation and redeployment.
Value Classes 主要用于扩展已有类的方法和创建类型安全的数据类型，功能上类似隐式转换，但是在运行时比隐式转换更节省内存。 所有的 Value Classes 都继承自 AnyVal ，例如：class Wrapper(val underlying: Int) extends AnyVal扩展已有类的方法结合 implicit classes ，我们可以利用 Value Class 扩展已有类的方法， Scala 基础类库中的 RichInt 就是一个很好的例子，正是因为 RichInt 定义了 toHexString 方法
As a principal of the school, you would like to assign each student to one of the 2 classes such that The number of students in the classes may be equal or different, by your choice. such partitions, you want to choose one in which the absolute difference between skill levels of the classes case, output a single integer, the minimum possible absolute difference between skill levels of two classes Note that you cant assign like , or because classes have even number of students. , is also not possible

CSS伪类选择器根据其他条件匹配组件，而不一定由文档树定义。CSS 伪类 是添加到选择器的关键字，指定要选择的元素的特殊状态。
在这个项目中，我们将使用环境处理Core Data，但在这里我将向您展示它的另一个重要用途：size classes。size classes 是苹果完全模糊的方式告诉我们的视图有多大的空间。 要演示实际的 size classes，我们可以创建一个具有跟踪当前 size classes 的属性的视图，并将其属性显示在文本视图中：struct ContentView: View { @Environment 译自 Using size classes with AnyView type erasure

eclipse下面创建的Maven项目，使用mybatis。eclipse里面能正常启动，在idea中一直卡在maybatis 加载位置。
classes = classesMapper.selectClasses(1); System.out.println(classes = + classes); } @Test @Ignore public void selectClassesByAnnotation() { Classes classes = classesMapper.selectClassesByAnnotation(1 Classes classes = classesMapper.selectClassesByProvider(1); System.out.println(classes = + classes); { Classes classes = classesMapper.getUserListByClassesId(1); System.out.println(classes = + classes System.out.println(classes = + classes); }}整个项目的搭建和代码过程就结束了，这里贴下项目的gitHub地址，需要代码的可以自己去下载。
