Question

谁能帮我修改一下，让这个程序能运行

import java.util.Scanner;

public class myBirthday
{
public static void main(String[] args)
{
int date, month, year;
String name;

Scanner scan = new Scanner (System.in);

System.out.println ("Your name: ");
name = scan.nextLine();
// Ask for the user's name

System.out.println ("Day:");
date = scan.nextInt();
// Ask for the user's birth date

System.out.println ("Month:");
month = scan.nextInt();
// Ask for the user's month of birth

System.out.println ("Year:");
year = scan.nextInt();
// Ask for user's year of birth

System.out.println ("Your name is:" +name);
System.out.println ("The length of your name is "+name.length());
// Print out the name results

System.out.println("Your birthday is " + year + month + date);

myBirthday user = new myBirthday(name, date, month, year);

System.out.println("Your birthday is " + user.oddoreven(Date) );
System.out.println("The month name of your birth is: " + user.monthName(Month) );
System.out.println("The year of your birthday is:" +user.leapornot(Year) );
