java 参数化泛型的简介说明

实现思路:
    直接在泛型参数中使用泛型
	即可实现“参数化泛型”

package com.java265;
import java.util.Arraylist;
import java.util.List;
public class GenericsTester {
   public static void main(String[] args) {
      InfoClass<Integer, List<String>> InfoClass
         = new InfoClass<Integer, List<String>>();

      List<String> infos = new ArrayList<String>();

      infos.add("java265");
      infos.add("test");
      infos.add("web");      

      InfoClass.add(Integer.valueOf(10),infos);
      System.out.printf("Integer Value :%d\n", InfoClass.getFirst());
      System.out.printf("String Value :%s\n", InfoClass.getSecond());


   }
}

class InfoClass<T, S> {
   private T t;
   private S s;

   public void add(T t, S s) {
      this.t = t;
      this.s = s;
   }

   public T getFirst() {
      return t;
   }

   public S getSecond() {
      return s;
   }
}
