You may know that the variable gives named storage that programs can access. Every variable in Java has a unique type that specifies its memory size, the range of operations that can be performed on the variable, and the range of values stored in memory. To compute data, sometimes you need...

说到TypeVariable就不得不提起java泛型中另一个比较重要的接口对象,GenericDeclaration接口对象。该接口用来定义哪些对象上是可以声明(定义)范型变量,所谓范型变量就是或者, 也就是TypeVariable这个接口的对应的对象,TypeVariable中的D是extends GenericDeclaration的,用来通过范型变量反向获取拥有这个变量的GenericDeclaration。

java TypeVariableImpl 获取泛型的class java获取泛型的实际类型, Java5的泛型语法已经有太多书讲了,这里不再打字贴书。GP一定有用,不然Java和C#不会约好了似的同时开始支持GP。但大家也清楚,GP和Ruby式的动态OO语言属于不同的意识形态,如果是一人一票,我想大部
