Class.forName("").newInstance()返回的是object 而有一些:Class.forName(xxx.xx.xx).newInstance(),为什么会有这两种写法呢? 刚才提到,Class.forName("");的作用是要求JVM查找并加载指定的类,如果在类中有静态初始化器的话,JVM必然会执行该类的静态代码段。而在JDBC规范中明确要求这个Driver类必须向DriverManager...

所有類別最終都是衍生自單一根物件 – 所有 Java 物件都是衍生自java.lang.Object,而所有 C# 物件都是衍生自System.Object。 類別的執行個體均為參考類型。 存取執行個體的屬性和方法時,您會使用 "." 運算子。 透過new運算子,在堆積上建立所有類別執行個體。
