T t=(T)list.get(0); 二、如何创建一个Class<T>类型的实例? 就像使用非泛型代码一样,有两种方式:调用方法 Class.forName() 或者使用类常量X.class。 Class.forName() 被定义为返 回 Class<?>。另一方面,类常量 X.class 被定义为具有类型 Class<X>,所以 String.class 是Class<String> 类型的。 三、方...
不同于TList类,TObjectList类的Add, Remove, IndexOf, Insert等方法都需要传递TObject对象作为参数,由于有了编译期的强类型检查,使得TObjectList比TList更适合保存对象。 此外TObjectList对象有OwnsObjects属性。当设定为True (默认值),同TList类不同,TObjectList对象将销毁任何从列表中删除的对象。 无论是调用Del...

参数化类型,就是我们平常所用到的泛型List、Map; 数组类型,并不是我们工作中所使用的数组String[] 、byte[],而是带有泛型的数组,即T[] ; 基本类型,也就是我们所说的java的基本类型,即int,float,double等 空接口 Type是个空接口,没有定义任何方法,通过多态提高了程序的扩展性,具体实现去看下面的子类; ...
