不知道是不是你要的package test;

import java.util.Scanner;

public class Number {

/**

* @param args

*/

public static void main(String[] args) {

int count = 15;

int val = 5;

Scanner input = new Scanner(System.in);

System.out.print("請輸入開始數：");

int inputnumber = input.nextInt();

int backnumber = (inputnumber - 1) % (val - 1);

int startnumber = inputnumber - backnumber;

for (int i = 0; i < val; i++) {

if (startnumber <= count) {

System.out.println(startnumber++);

}

}

}

}
