用for迴圈列印九九乘法表

public class multiply {public static void main (String args[]) {for(int i = 1 ;i <= 9; i++) {for(int j = 1; j <= i; j++) {int sum = i * j;System.out.print(i +"*"+ j + "=" + sum +"\t");}System.out.println();}}}

單迴圈實現

 int j = 1;for (int i = 1; i <= j && j <= 9; i++) {System.out.print(i + "*" + j + "=" + (j * i) + "\t");if (i == j) {j++;i = 0;System.out.println();}}
