首先是Object類
public class StuVO {
private String name;
private int score;
public StuVO(String name, int srore) {
this.name = name;
this.score = srore;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getScore() {
return score;
}
public void setScore(int srore) {
this.score = srore;
}
}
然后是處理的代碼
import com.catk.entity.StuVO;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
public class ListSort {
public static void main(String[] args) {
List<StuVO> list = new ArrayList<>();
list.add(new StuVO("AAA",90));
list.add(new StuVO("BBB",150));
list.add(new StuVO("CCC",12));
list.add(new StuVO("DDD",64));
list.add(new StuVO("EEE",5));
for(int i = 0;i < list.size();i++){
System.out.println(list.get(i).getName()+" "+list.get(i).getScore());
}
System.out.println("--------");
Collections.sort(list, new Comparator<StuVO>() {
@Override
public int compare(StuVO o1, StuVO o2) {
int i = o1.getScore() - o2.getScore();
return i;
}
});
for(int i = 0;i < list.size();i++){
System.out.println(list.get(i).getName()+" "+list.get(i).getScore());
}
}
}
通過Collection.sort進行排序。
