come ordinare una lista di oggetti

[abcd1000]

Ciao a tutti, ho scritto il codice per ordinare degli oggetti, ma non vengono ordinati, ecco il codice:

package it.ordinare.liste.test;


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


public class Main {


    /**
     * @param args
     */
    public static void main(String[] args) {
        ArrayList<InsertionBean> insertionBeanList = new ArrayList<InsertionBean>();
        InsertionBean insertionBean1 = new InsertionBean();
        insertionBean1.setId(1);
        insertionBean1.setPrice(100000);
        insertionBean1.setTitle("titolo 1");
        InsertionBean insertionBean2 = new InsertionBean();
        insertionBean1.setImageName("7_1.jpg");
        insertionBean2.setId(2);
        insertionBean2.setPrice(200000);
        insertionBean2.setTitle("titolo 2");
        insertionBean2.setImageName("6_1.jpg");
        InsertionBean insertionBean3 = new InsertionBean();
        insertionBean3.setId(3);
        insertionBean3.setPrice(300000);
        insertionBean3.setTitle("titolo 3");
        insertionBean3.setImageName("5_1.jpg");
        insertionBeanList.add(insertionBean1);
        insertionBeanList.add(insertionBean2);
        insertionBeanList.add(insertionBean3);
        if (insertionBeanList != null && !insertionBeanList.isEmpty()) {


            /** ordino per prezzo crescente */
            Collections.sort(insertionBeanList,
                    new ComparatorInsertionPriceHighToLow());
            System.err.println("crescente ins1 price: "
                    + ((InsertionBean) insertionBeanList.get(0)).getPrice());
            System.err.println("crescente ins2 price: "
                    + ((InsertionBean) insertionBeanList.get(1)).getPrice());
            System.err.println("crescente ins3 price: "
                    + ((InsertionBean) insertionBeanList.get(2)).getPrice());
            
            /** ordino per prezzo decrescente */
            Collections.sort(insertionBeanList,
                    new ComparatorInsertionPriceLowToHigh());
            System.err.println("decrescente ins1 price: "
                    + ((InsertionBean) insertionBeanList.get(0)).getPrice());
            System.err.println("decrescente ins2 price: "
                    + ((InsertionBean) insertionBeanList.get(1)).getPrice());
            System.err.println("decrescente ins3 price: "
                    + ((InsertionBean) insertionBeanList.get(2)).getPrice());


        }
    }
}


package it.ordinare.liste.test;




import java.util.Comparator;


public class ComparatorInsertionPriceHighToLow implements Comparator<InsertionBean> {


    @Override
    public int compare(InsertionBean arg0, InsertionBean arg1) {
        int price0 = arg0.getPrice();
        int price1 = arg1.getPrice();
//        System.out.println("price0: "+price0);
//        System.out.println("price1: "+price1);
        int result = (price0 > price1) ? 0 : 1;
//        System.out.println("HighToLow result: "+result);
        return result;
    }


}

package it.ordinare.liste.test;




import java.util.Comparator;


public class ComparatorInsertionPriceLowToHigh implements Comparator<InsertionBean> {


    @Override
    public int compare(InsertionBean arg0, InsertionBean arg1) {
        int price0 = arg0.getPrice();
        int price1 = arg1.getPrice();
//        System.out.println("price0: "+price0);
//        System.out.println("price1: "+price1);
        int result = (price0 < price1) ? 0 : 1;
//        System.out.println("lowToHight result: "+result);
        return result;
    }
} 

Il risultato è questo:

crescente ins1 price: 100000
crescente ins2 price: 200000
crescente ins3 price: 300000


decrescente ins1 price: 100000
decrescente ins2 price: 200000
decrescente ins3 price: 300000

Mentre io volevo questo:

crescente ins1 price: 100000
crescente ins2 price: 200000
crescente ins3 price: 300000

decrescente ins1 price: 300000
decrescente ins2 price: 200000
decrescente ins3 price: 100000

Sapete dirmi dove sbaglio?

grazie
