*3.5（给出将来的日期）编写一个程序，提示用户输入代表今天日期的数字（周日为0，周一为1，……，周六为6）。同时，提示用户输入一个今天之后的天数，作为代表将来某天的数字，然后显示这天是星期几。 下面是一个运行示例： Enter today’s day:1 Enter the number of days elapsed since today:3 Today is Monday and the future day is Thursday Enter today’s day:0 Enter the number of days elapsed since today:31 Today is Sunday and the future day is Wednesday
*3.5(Find future dates) Write a program that prompts the user to enter an integer for today’s day of the week (Sunday is 0, Monday is 1, . . . , and Saturday is 6). Also prompt the user to enter the number of days after today for a future day and display the future day of the week. Here is a sample run: Enter today’s day:1 Enter the number of days elapsed since today:3 Today is Monday and the future day is Thursday Enter today’s day:0 Enter the number of days elapsed since today:31 Today is Sunday and the future day is Wednesday

package chapter03; import java.util.Scanner; public class Code_05 { public static void main(String[] args){ Scanner input = new Scanner(System.in); System.out.print("Enter today's day: "); int number1 = input.nextInt(); System.out.print("Enter the number of days elapsed since today: "); int number2 = input.nextInt(); System.out.print("Today is "); method(number1); System.out.print(" and the future day is "); method((number2 + number1) % 7); } static void method(int n){ switch (n){ case 0:System.out.print("Sunday");break; case 1:System.out.print("Monday");break; case 2:System.out.print("Tuesday");break; case 3:System.out.print("Wednesday");break; case 4:System.out.print("Thursday");break; case 5:System.out.print("Friday");break; case 6:System.out.print("Saturday");break; } } } 结果显示： Enter today's day: 1 Enter the number of days elapsed since today: 3 Today is Monday and the future day is Thursday Process finished with exit code 0
