java - 能被5或6整除

Question

我正在尝试编写一个程序，其中列出 100-1000 之间可被 5 或 6 整除的所有数字。这是我使用的代码:

public class divisibleBy5and6 {
    public static void main (String[] args) {

        j = 1; 
        int number = 100;
        while (number < 1001) {
            if (number % 6 == 0 || number % 5 == 0) {
                System.out.print(number + ", ");
                number++;
                j++; }

            if (j % 10 == 0 && j != 0) {
                System.out.println();
                j++; }
            else {
                number++;
            }
        }

我使用 int j 来制作它，因此每行有 9 个。这是我的输出:

100, 102, 105, 108, 110, 114, 120, 125, 130, 
132, 135, 138, 140, 144, 150, 155, 160, 162, 
165, 168, 170, 174, 180, 185, 190, 192, 195, 
198, 200, 204, 210, 215, 220, 222, 225, 228, 
230, 234, 240, 245, 250, 252, 255, 258, 260, 
264, 270, 275, 280, 282, 285, 288, 290, 294, 
295, 300, 305, 310, 312, 315, 318, 320, 324, 
325, 330, 335, 340, 342, 345, 348, 350, 354, 
355, 360, 365, 370, 372, 375, 378, 380, 384, 
385, 390, 395, 400, 402, 405, 408, 410, 414, 
415, 420, 425, 430, 432, 435, 438, 440, 444, 
445, 450, 455, 460, 462, 465, 468, 470, 474, 
475, 480, 485, 490, 492, 495, 498, 500, 504, 
505, 510, 515, 520, 522, 525, 528, 530, 534, 
535, 540, 545, 550, 552, 555, 558, 560, 564, 
565, 570, 575, 580, 582, 585, 588, 590, 594, 
595, 600, 605, 610, 612, 615, 618, 620, 624, 
625, 630, 635, 640, 642, 645, 648, 650, 654, 
655, 660, 665, 670, 672, 675, 678, 680, 684, 
685, 690, 695, 700, 702, 705, 708, 710, 714, 
715, 720, 725, 730, 732, 735, 738, 740, 744, 
745, 750, 755, 760, 762, 765, 768, 770, 774, 
775, 780, 785, 790, 792, 795, 798, 800, 804, 
805, 810, 815, 820, 822, 825, 828, 830, 834, 
835, 840, 845, 850, 852, 855, 858, 860, 864, 
865, 870, 875, 880, 882, 885, 888, 890, 894, 
895, 900, 905, 910, 912, 915, 918, 920, 924, 
925, 930, 935, 940, 942, 945, 948, 950, 954, 
955, 960, 965, 970, 972, 975, 978, 980, 984, 
985, 990, 995, 1000, 

这显然是不对的，因为我缺少像 115 这样的数字。我做错了什么？

您需要将数字增量与 if/else 语句分开。无论如何，它应该在每次迭代中发生......

int j = 1; 
int number = 100;
while (number < 1001) {
  if (number % 6 == 0 || number % 5 == 0) {
    System.out.print(number + ", ");
    j++; 
   }
   if (j % 10 == 0) {
     System.out.println();
   }
   number++;
}
