编一个手机通讯录，刚开始显示你有6个联系人，然后显示是否关掉手机，不关掉就先显示第一个联系
人的信息，然后你可以你可以通过前进，后退选择其他联系人，并且你可以呼叫，发短信，编辑

你需要在这个程序里填上所需的代码import java.util.Scanner;

public class Ass
{
private MobileFacilities myPhone;
private boolean tracing;
private Scanner sc;

public CallOrText()
{
}

public void intro()
{
}

public void use()
{
}

public void trace(String message)
{
if(tracing)
{
System.out.println("CallOrText: " + message);
}
}
}
以下是你所需要获取的信息，你可以调用里面的信息
import java.util.Random;
import java.util.Scanner;
