一个使用了模板的例子：
对立观点：
In this modern society, people always confront the dilemma of choosing whether AAA or BBB. This problem is a much debated one in that it affects everybody in his or her daily life. People may prefer one to the other although some may have no opinions about either at all. Before rendering my opinion, I think it is necessary to take a glance at the arguments on both sides.
It is quite rational for average people to choose BBB because of the obvious reason that 原因.The most extreme manifestation of this idea is the fact that 例子.Even so, however, many advantages of BBB over AAA will be obscured by its considerable drawbacks such as 例子.Therefore we have no complete evidence to suggest that BBB is always better than AAA. Moreover, a close scrutiny of the potential benefits of choosing AAA would reveal how flimsy it is to stick to the propensity to BBB over AAA.
There are numerous reasons for my preference for AAA, and I shall here explore only a few of the most important ones. One chief reason is that 原因一.And I can think of no better illustration of the idea than the fact that 例子一. The above is only part of the important aspects, and another one with equal significance with respect to choosing between the two lies in the development of the proposition that 原因
二. This well explains the undeniable fact that 例子二. Besides, a further reason why I advocate AAA is that 原因三.This may explain why 例子三.
Last but not least, there is also a more practical reason why I would choose AAA, that is 原因四.
All in all, taking into account all these merits that AAA boasts of, we may safely arrive at the conclusion that the advantages of AAA outweigh any benefit we can get from BBB and choosing AAA is a rather wise decision.
第二篇：set、map集合list接口实例 文档
1.Set(集合)里面的元素是无序的，但没有重复的元素有两个实现类HashSet（LinkHashSet）和TreeSet,TreeSet有排序功能（Set set=new TreeSet();set.add(new Integer(8)); set.add(new Integer(4)); set.add(new Integer(7));）输出后的结果是：4 7 8 Eg:
package test;
import java.util.*;
public class Set{
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2.List(列表<接口>)以线性方式存储，有序，允许重复主要实现类有LinkList（采用链表数据结构）和ArrayList(代表可大可小的数组)
Eg：
package test;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;
public class Map {
public static void main(String[] args) { List list=new ArrayList(); list.add(10); public static void main(String[] args) { } //先实例化一个set Set<String> stringSet=new HashSet<String>(); //向set里面添加元素 stringSet.add("123"); stringSet.add("wer"); stringSet.add("345"); //将set里的元素取出 Iterator<String> stringIter=stringSet.iterator(); while(stringIter.hasNext()){ } System.out.println("stringSet里面有"+stringSet.size()+"元素"); String str=stringIter.next(); System.out.println(str); System.out.println("~~~~~~~~~~~");
list.add(34); //对list数组进行自然排序 Collections.sort(list); //依次检索输出list的所有对象 for(int i=0;i<list.size();i++){ } Iterator Iter=list.iterator(); while(Iter.hasNext()){ } System.out.println(Iter.next()); System.out.println(list.get(i)); // // // }
} 3.Map（映射<集合>）是无序的，是一种把键对象和值对象进行映射的集合，它每一个元素都包含一对键对象和值对象，给出键对象就可以得到值对象，键对象不允许重复，对值没有要求，多个任意键对象可以映射到一个值对象上；如果有相同键对象，最后一次加入的键对象和值对象将会覆盖以前的；
Eg：
package test;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;
import java.util.TreeMap;
public class NewMap {
public static void main(String[] args) { //向map里添加键值对 //如果要对键进行排序Map map=new TreeMap(); Map<Integer,String> map=new TreeMap<Integer,String>(); //Map map=new HashMap(); map.put(1, "yi"); map.put(23, "er"); map.put(12, "san"); map.put(3, "si"); //遍历map
} } Iterator<Integer> stringIter=keys.iterator(); while(stringIter.hasNext()){ } int key=stringIter.next(); String value=(String) map.get(key);//根据键key得到value的值 System.out.println(key+"---"+value);
