				System.out.println(" This month 31 God ");
				break;
			case 4: case 6 :case 9 :case 11:
				System.out.println(" This month 30 God ");
				
				break;
			case 2:
				if(year%4==0&&year%100!=0||year%400==0){

				}
				else{
				      System.out.println(" This month 28 God ");	
			}	
				break;
		}
	}
}

3、 Graphic printing task
In the console , Write three Demo, Output the following figures respectively ：

 

public static void main(String[]args) {
		for(int i =0;i<5;i++) {
			for(int j =0;j<i+1;j++) {
				System.out.print("*");
		}
		System.out.println();
	 }
   }	
}

 

public static void main(String[] args) {
		for(int i =0;i<5;i++) {
			for(int j =0;j<5-i;j++) {

			}
			System.out.println();
		}
    }
}

 

 

public static void main(String[] args) {
		for(int i =0;i<5;i++) {
			for(int j=0;j<4-i;j++) {
				System.out.print(" ");

public static void main(String[] args) {
		System.out.println(" multiplication table ");
		for(int i=0;i<10;i++) {
			for(int j=1;j<i+1;j++) {
				System.out.print(j+"*"+i+"="+j*i+" ");
			}
			System.out.println();
		}
	}
}

 5、 Print all daffodils in three digits
So-called “ Narcissistic number ” That is, an integer satisfies that its value is equal to the cube sum of each digit .
Such as : 153 It's a narcissus number , because 153= 1³+5³+3³

 

public static void main(String[] args) {
		for(int i=100;i<1000;i++) {	
			int ge =i%10;
			int shi=i/10%10;
			int bai=i/100%10;
			if(ge*ge*ge+shi*shi*shi+bai*bai*bai==i) {
				System.out.println(i);		
	        }
        }
    }
}
