java 泛型嵌套

java 泛型嵌套：

<pre name="code" class="java">class Info<T,V>{private T var;private V value; public void setVar(T var){this.var=var;}public T getVar(){return this.var;}public void setValue(V value){this.value=value;}public V getValue(){return this.value;}public Info(T var,V value){this.var=var;this.value=value;}}class Demo<S>{private S info;public void setInfo(S Info){this.info=info;}public S getInfo(){return this.info;}public Demo(S info){this.info=info;}}public class Fanxingqiantao{public static void main(String[] args){Demo<Info<String,Integer>> d = null;//Info 作为Demo的泛型类型Info<String,Integer> i = null;//实例化Info 类型i = new Info<String,Integer>("java",1);d = new Demo<Info<String,Integer>>(i);//添加到Demo中System.out.println("name:"+ d.getInfo().getVar());System.out.println("age:"+ d.getInfo().getValue());}}
