java 编写手机短信,高手赐教!!!

编写短信类,(shortMesg),它具有的属性是:目标手机号码(phoneNo)和短信内容(content).编写短信发送类(SendMesg),创建一条短信,提示用户输入手机号码和短信内容,然后显示XX短信已经发送到XX手机.

我是这么写的,写了三个类:
1:package bao;

public class Short {
String phoneNo;
String Content;
}

二:package bao;
import java.util.*;
public class Send {
public String toString() {

Short message=new Short();

System.out.print("发送给谁?");
message.phoneNo=new Scanner(System.in).next();

System.out.print("短信内容?");
message.Content=new Scanner(System.in).next();

return "内容" + message.Content + "号码" + message.phoneNo;
}
}

三:package bao;
public class san {
System.out.println(message);
}

第三个类括号里的massage下与一条红线,eclipse总是报错,不知道哪错了,还有就是第二个类return "内容" + message.Content + "号码" + message.phoneNo;为什么得加对象名message,不加就报错???
请高手赐教!
我在System.out.println(message);的上面添加了public static void main(String[] args) {
怎么还是报错?
第二句话没看太明白,能不能把代码给写出来?

package examples;

import java.util.Scanner;
public class Entry {

public static void main(String args []) {
Scanner sc=new Scanner(System.in);
String pno,msg;
System.out.print("请输入短信内容:");
msg=sc.nextLine();
System.out.println("请输入目标手机号码：");
pno=sc.nextLine();
ShortMesg newmsg=new ShortMesg();
newmsg.setPhoneNO(pno);
newmsg.setMessage(msg);
SendMesg send=new SendMesg(newmsg);
send.send();
}

}

class ShortMesg {

public ShortMesg() {

}

private String pno,msg;

public void setPhoneNO(String pno) {
this.pno=pno;
}

public String getPhoneNO() {
return this.pno;
}

public void setMessage( String msg) {
this.msg=msg;
}

public String getMessage() {
return this.msg;
}
}

class SendMesg {

private ShortMesg mms;

public SendMesg(ShortMesg mms) {
this.mms=mms;
}

public void send() {
System.out.println("短信内容： "+mms.getMessage());
System.out.println("目标手机： "+mms.getPhoneNO()+"\n");
}
}

1.将System.out.println(message); 放到一个方法下面，就不会报错了~~
2. phoneNo和Content对视对象的属性，如果没有对象从哪里来的属性啊~~
