JAVA集合类-Person类

这里的所有类都是在后面的会用到的，用于数据存储。

第一个：

package collectiontest;

public class Person implements Comparable {

private String name;
private long card;

public Person(String name, int card) {
this.name=name;
this.card=card;
}

public Person() {
// TODO Auto-generated constructor stub
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public long getCard() {
return card;
}

public void setCard(long card) {
this.card = card;
}

@Override
public int compareTo(Object o) {
Person p=(Person)o;
String s1=CnToSpell.getFullSpell(this.name);
String s2=CnToSpell.getFullSpell(p.getName());
return s1.compareTo(s2);
}

public int hashCode(){//重写
final int PRIME=31;
int result=1;
result=PRIME*result+(int)(card^(card>>>32));
result=PRIME*result+((name==null)?0:name.hashCode());
return result;
}

public boolean equals(Object obj){//重写
if(this==obj)return true;
if(obj==null)return false;
if(getClass()!=obj.getClass())
return false;
final Person other=(Person)obj;
if(card!=other.getCard())
return false;
if(name==null){
if(other.name!=null){
return false;
}
}else if(!name.equals(other.name)){
return false;
}

return true;
}

}



第二个：

package collectiontest;

import java.util.Comparator;

public class Person2 implements Comparable {
private String name;
private long card;

public Person2(String name, long card) {
this.name = name;
this.card = card;
}

@Override
public int compareTo(Object o) {
// TODO Auto-generated method stub
Person2 person = (Person2) o;
int result = card > person.card ? 1 : (card == person.card ? 0 : 0 - 1);
return result;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public long getCard() {
return card;
}

public void setCard(long card) {
this.card = card;
}

//内部类
static class PersonComparator implements Comparator{
public static final int NAME=1;
public static final int ID_CARD=2;
private int orderByColumn=1;
public static final boolean ASC=true;
public static final boolean DESC=false;
private boolean orderByModel=true;

@Override
public int compare(Object o1, Object o2) {
Person2 p1=(Person2)o1;
Person2 p2=(Person2)o2;
int result=0;
switch(orderByColumn){

default:
String s1=CnToSpell.getFullSpell(p1.getName());
String s2=CnToSpell.getFullSpell(p2.getName());
if(orderByModel)//升序
result=(int)(p1.getCard()-p2.getCard());
else//降序
result=s2.compareTo(s1);

break;
case 2:
if(orderByModel)
result=(int)(p1.getCard()-p2.getCard());
else
result=(int)(p2.getCard()-p1.getCard());
}
return result;
}
public void orderByColumn(int orderByColumn){
this.orderByColumn=orderByColumn;

}
public void orderByModel(boolean orderByModel){
this.orderByModel=orderB
