package com.infoearth;

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

/*

 */
public class ListSort {
	
	public ListSort(ArrayList list){
		
		Comparator comp = new MyComparator();
		Collections.sort(list, comp);
		
	}
	
	public static void main(String[] args){	
		
		ArrayList list =new ArrayList();
		
		list.add(new Word("001", 0.22, 1));
		list.add(new Word("002", 0.72, 1));
		list.add(new Word("003", 0.42, 0));
		list.add(new Word("004", 0.12, 0));	
		
		ListSort application = new ListSort(list);
		
		for(int i = 0; i < list.size(); i++){
			Word w = (Word)list.get(i);
			System.out.println(w.id);
		}
		
	}
