JAVA基础

按照拼音排序：
测试类：

package Test;

import java.text.Collator;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;





public class MySort{
	public static void main(String[] args) {
		List list = new ArrayList();
		list.add("正在");
		list.add("吧啊啊");
		list.add("啊啊啊");
		list.add("看看");
		list.add("aaa");
	/*	第一种方法
	 * Comparator cmp=Collator.getInstance(java.util.Locale.CHINA);
		Collections.sort(list,cmp);*/
		Collections.sort(list, new Comparator<Object>() {
			public int compare(Object o1, Object o2) {
				String str1 = PingYinUtil.getPingYin((String) o1);
				String str2 = PingYinUtil.getPingYin((String) o2);
				return str1.compareTo(str2);
			}
		});
		for(Object obj:list){
			System.out.println(obj);
		}
		
	}
	
	
}

辅助类：
