Note: The phrase "instantiating a class" means the same thing as "creating an object." When you create an object, you are creating an "instance" of a class, therefore "instantiating" a class. (实例化一个类和创建一个对象是同一件事,当你创建一个对象时,意味着你正在创建一个类的实例,相当...
TheObjectclass, in thejava.langpackage, sits at the top of the class hierarchy tree. Every class is a descendant, direct or indirect, of theObjectclass. Every class you use or write inherits the instance methods ofObject. You need not use any of these methods, but, if you choose to do ...
Scala 进阶(1)—— 反射 object 和 class 1. Scala 的 反射 关于Scala 反射的具体内容,可以参考官方文档:https://docs.scala-lang.org/overviews/reflection/overview.html 这篇文章写一点自己的理解: 由于Scala 编译出来的内容是与 Java 相同的字节码文件,所以可以使用 Java 反射的相关方法来实现 Scala 代码的...

在java中,我们要使用一个单例模式时,最基本的方法是: publicclassObj{privateObj(){}privatestaticObjINSTANCE;publicstaticObjgetObj(){if(INSTANCE==null)INSTANCE=newObj();returnINSTANCE;}} 1. 2. 3. 4. 5. 6. 7. 8. 9. object Obj就搞定了,这样的黑魔法是怎么实现的呢?
The Java Language Specification, Third Edition (15.8.2 Class Literals) hashCode public inthashCode() 返回该对象的哈希码值。支持此方法是为了提高哈希表(例如java.util.Hashtable提供的哈希表)的性能。 hashCode的常规协定是: 在Java 应用程序执行期间,在对同一对象多次调用hashCode方法时,必须一致地返回相同的整...
2.1 使用 Java 的方式反射 Scala class 和反射 Java 的 class 步骤完全一致,所以不赘述,直接贴代码: test("Should reflect Scala class in Java style") { val app = new ProvisioningApp val field = classOf[ProvisioningApp].getDeclaredField("strInClazz") ...
