下面这个程序写死了，怎么把它变成面向对象带参数的程序啊，求大家帮帮忙

Question

public static void main(String[] args) {  boolean flag=true;  while(flag){   Scanner sc=new Scanner(System.in);   System.out.println("请输入年份");   int year=sc.nextInt();   System.out.println("请输入月份");   int month=sc.nextInt();   //当前月的天数   int currentDay=0;   //闰年计数   int count=0;   if(year<1900){    System.out.println("您输入的年份不符合要求，请输入大于1900的年份");    continue;   }   for(int i=1900;i<year;i++){    if((i%4==0&&i%100!=0)||i%400==0){     count++;    }   }   int preYear=(year-1900)*365+count;   int totalMonthDay=0;   for(int i=1;i<=month;i++){    int days=0;    switch (i) {    case 2: {     if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {      days = 29;     } else {      days = 28;     }     break;    }    case 4:    case 6:    case 9:    case 11: {     days = 30;     break;    }    default:     days = 31;     break;    }    if(i==month){//当前月的天数     currentDay=days;    }        totalMonthDay+=days;   }   int week=(preYear+totalMonthDay-currentDay+1)%7;   System.out.println("星期天\t星期一\t星期二\t星期三\t星期四\t星期五\t星期六");   int blank=0;   //打印日期前空格   for(int i=1;i<=week;i++){     blank++;     System.out.print("\t");   }  //打印日期   for(int i=1;i<=currentDay;i++){    if(blank%7==0){     System.out.println();    }    blank++;    System.out.print(i+"\t");   }   String l=sc.next();   System.out.println("继续按Y");   if(l.equalsIgnoreCase("l")){    continue;   }   else{    System.out.println("退出系统");    break;   }  } }
