Java开发万年历

自己做出来的万年历：

以下代码：

public class Test2 {
 public static void main(String[] args) {
  Scanner sc = new Scanner(System.in);
  System.out.println("请输入年份和月份：");
  int y = sc.nextInt();
  int m = sc.nextInt();
  GregorianCalendar gc = new GregorianCalendar();
  int theYear = gc.get(Calendar.YEAR);
  int theDay = gc.get(Calendar.DATE);
  //把年份和月份进行设置
  gc.set(Calendar.YEAR, y);
  gc.set(Calendar.MONTH, m);
  System.out.println(gc.get(Calendar.YEAR));
  while(gc.get(Calendar.YEAR) == y) {
   System.out.println("现在是：" + gc.get(Calendar.YEAR) + "年" + (gc.get(Calendar.MONTH) + 1) + "月");
   int month = gc.get(Calendar.MONTH);
   gc.set(Calendar.DATE, 1);
   System.out.println("Sun Mon Tue Wed Thu Fri Sat");
   for(int i = 0; i < gc.get(Calendar.DAY_OF_WEEK) - 1; i++) {
    System.out.print("    ");
   }
   while(gc.get(Calendar.MONTH) == month) {
    int day = gc.get(Calendar.DATE);
    if(day < 10) {
     System.out.print(" ");
    }
    System.out.print(" " + day);
    if(gc.get(Calendar.DATE) == theDay) {
     if(gc.get(Calendar.MONTH) == Calendar.JUNE) {
      if(gc.get(Calendar.YEAR) == theYear) {
       System.out.print("*");
      }
     }
    } else {
     System.out.print(" ");
    }
    if(gc.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY) {
     System.out.println();
    }
    gc.add(Calendar.DATE, 1);
    
   }
   
   System.out.println();
   return;
   /*if(gc.get(Calendar.MONTH) == Calendar.JUNE) {
    if(gc.get(Calendar.YEAR) == theYear) {
     System.out.println("===================================");
    }
   } else {
    System.out.println("----------------------------------");
   }
   */
  }
  
 }
