当前月份简单日历功能的实现

使用JAVA语言编写模块化程序，实现一个简单的日历`：根据输入的当前日期自动生成本月的日历并特殊标注当前日期；

//定义Date类
public class Date {
	int Year;
	int mouth;
	int day;
	int firstday;
	int maxday;
   Date(int Year,int mouth,int day,int firstday,int maxday)
   {
	   this.Year=Year;
	   this.mouth=mouth;
	   this.day=day; 
	   this.firstday=firstday;
	   this.maxday=maxday;
   }
   
   int GetYear() {
		return Year;
	}
	void SetYear(int Year) {
		this.Year=Year;	
	}
	
	int Getmouth() {
		return mouth;
	}
	void Setmouth(int mouth) {
		this.mouth=mouth;
	}
	int Getday() {
		return day;
	}
	void Setday(int day) {
		this.day=day;	
   }
	//本月第一天是第一周的第几天
	void Setfirstday(int firstday) {
		this.firstday=firstday;	
   }
	//本月的最大天数
	void Setmaxday(int maxday) {
		this.maxday=maxday;	
   }
	
	
	//日历的显示
	void   printInfoo() {
		System.out.println("日\t一\t二\t三\t四\t五\t六\n");
		for (int j = 1; j < firstday; j++) {
			System.out.print("\t");
		}
 
		for (int i = 1; i <= maxday; i++) {
			if (i == day) {
				System.out.print("*");
			}
			System.out.print(i + "\t");
			if ((i - (8 - firstday)) % 7 == 0) {
				System.out.println("\n");
			}
 
		}
	}
		
	void   printInfo()
	{
	System.out.println("---------------------");
	System.out.println("当前日期："+Year+"年"+mouth+"月"+day+"日");	
	printInfoo();
    }
}

//定义class Now_date；
import java.util.Scanner;
public class Now_date {
	public static void main(String args[]) {
		Date Date1=new Date(2018,5,1,1,31);   //初始化当前日期
		
		//建立一个从键盘接受数据的扫描器(选择是否更改初始值)
		Scanner scanner = new Scanner(System.in);
		System.out.print("请输入Year:");
		int Year  = scanner.nextInt();
		Date1.SetYear(Year);
		System.out.print("请输入mouth:");
		int mouth = scanner.nextInt();
		Date1.Setmouth(mouth);
		System.out.print("请输入day:");
		int day= scanner.nextInt();
		Date1.Setday(day);	
		System.out.print("请输入firstday:");
		int firstday= scanner.nextInt();
		Date1.Setfirstday(firstday);	
		System.out.print("请输入maxday:");
		int maxday= scanner.nextInt();
		Date1.Setmaxday(maxday);	
		Date1.printInfo();
	}
}
