java 对List集合进行排序

Collections.sort(evidenceDetailVolist,new Comparator(){
public int compare(EvidenceDetailVo arg0, EvidenceDetailVo arg1) {
if(arg0.getUseId()-arg1.getUseId()>0){
return 1;
}else if(arg0.getUseId()-arg1.getUseId()<0){
return -1;
}else{
return arg0.getId().compareTo(arg1.getId());
}

        }    });
