我必须显示一个表格,用于检测2个数字的倍数。
我无法格式化输出。
倍数应打印左对齐,每列8个字符,每行5个。
我知道它应该很简单,但我无法弄清楚如何每行显示5个倍数。
任何人都可以帮忙吗?
public class Multiples_Loop_Table {
public static void main(String[] args)
{
int total = 0;
//table heading
System.out.println(" Integers from 300 to 200");
System.out.println(" -----------------------------");
for (int high = 300; high >= 200 && high <= 300; )
{
if ( (high % 11 == 0) != (high % 13 == 0))
{
System.out.printf("%-8d", high);
total += high;
}
high = high - 1;
}
//Total of all integers added togather
System.out.println("\nHere's the total for all integers: " + total );
//System.out.println("Here's the total number of integers found: " + );
//for every high add 1 to ?
示例:
299 297 275 273 264
260 253 247 242 234
231 221 220 209 208

您可以每n次打印一个新行,并使用col变量将其重置为0以保持跟踪。
public static void main(String[] args) {
int total = 0;
int col = 0;
// table heading
System.out.println(" Integers from 300 to 200");
System.out.println(" -----------------------------");
for (int high = 300; high >= 200 && high <= 300;) {
if ((high % 11 == 0) != (high % 13 == 0)) {
if (col == 5) {
System.out.println();
col = 0;
}
System.out.printf("%-8d", high);
total += high;
col++;
}
high = high - 1;
}
}
