本文實例講述了java實現List中對象排序的方法。分享給大家供大家參考，具體如下：
package com.test; import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; public class NewsManager { /** * @param args */ public static void main (String[] args) { List newss=getNewsList(); for(int i=0;i<newss.size();i++) { News news=(News)newss.get(i); System.out.println ("id:"+news.getId()); System.out.println("title:"+news.getTitle()); System.out.println("hits:"+news.getHits()); } } public static List getNewsList() { List list=new ArrayList(); News news1=new News(); news1.setHits(1); news1.setId(1); news1.setTitle("test1"); list.add (news1); News news2=new News(); news2.setHits(7); news2.setId(2); news2.setTitle("test2"); list.add(news2); News news3=new News(); news3.setHits(3); news3.setId(3); news3.setTitle("test3"); list.add(news3); News news4=new News(); news4.setHits(5); news4.setId(4 ); news4.setTitle("test4"); list.add(news4); // 按點擊數倒序Collections.sort(list, new Comparator<News>() { public int compare(News arg0, News arg1) { int hits0 = arg0.getHits(); int hits1 = arg1.getHits(); if (hits1 > hits0) { return 1; } else if (hits1 == hits0) { return 0; } else { return -1; } } } ); return list; } }希望本文所述對大家Java程序設計有所幫助。
