【JAVA实现九九乘法表】

使用Eclipse开发工具

外层循环控制行
内层循环控制列

public class ForTest {@Testpublic void test() {for (int i = 0; i < 9; i++) {for (int j = 0; j < i + 1; j++) {System.out.print((j + 1) + " * " + (i + 1) + " = " + (i + 1) * (j + 1) + "\t");}System.out.println("\n");}}}

• 然后双击选中test，右键选择run as下的junit Test

输出

1 * 1 = 11 * 2 = 22 * 2 = 41 * 3 = 32 * 3 = 63 * 3 = 91 * 4 = 42 * 4 = 83 * 4 = 124 * 4 = 161 * 5 = 52 * 5 = 103 * 5 = 154 * 5 = 205 * 5 = 251 * 6 = 62 * 6 = 123 * 6 = 184 * 6 = 245 * 6 = 306 * 6 = 361 * 7 = 72 * 7 = 143 * 7 = 214 * 7 = 285 * 7 = 356 * 7 = 427 * 7 = 491 * 8 = 82 * 8 = 163 * 8 = 244 * 8 = 325 * 8 = 406 * 8 = 487 * 8 = 568 * 8 = 641 * 9 = 92 * 9 = 183 * 9 = 274 * 9 = 365 * 9 = 456 * 9 = 547 * 9 = 638 * 9 = 729 * 9 = 81
