JAVA对List列表排序

NewsManager.java

package test;

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

public class NewsManager {

	 * @param args
	 */

//			System.out.println("id:" + news.getId());
			System.out.println("title:" + news.getTitle());
//			System.out.println("hits:" + news.getHits());
		}
