Javascript打印乘法表
### 回答1:

这是一份生成乘法表的java代码:
```
public class MultiplyTable {
public static void main(String[] args) {
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(j + "*" + i + "=" + i * j + " ");
}
System.out.println();
}
}
}
```

生成打印Java乘法表的代码如下:
```
public class MultiplicationTable {
public static void main(String[] args) {
int num = 9; // 表示乘法表的最大数字
// 打印乘法表的第一行
for (int i = 1; i <= num; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(j + " × " + i + " = " + (i * j) + "\t");
}
System.out.println();
}
}
}
```
以上代码实现了生成并打印一个乘法表,乘法表的最大数字可以通过修改`num`变量来指定。代码中使用了两个嵌套的`for`循环,外层循环控制行数,内层循环控制每行的列数。最内层循环打印了每个乘法表达式和结果,并使用`System.out.print()`方法打印在同一行,通过制表符`\t`来分隔每个乘法表达式。最外层循环每次循环都会打印一行乘法表达式,然后通过`System.out.println()`方法换行。
运行该代码,会在控制台输出如下乘法表:
```
1 × 1 = 1
1 × 2 = 2 2 × 2 = 4
1 × 3 = 3 2 × 3 = 6 3 × 3 = 9
1 × 4 = 4 2 × 4 = 8 3 × 4 = 12 4 × 4 = 16
1 × 5 = 5 2 × 5 = 10 3 × 5 = 15 4 × 5 = 20 5 × 5 = 25
1 × 6 = 6 2 × 6 = 12 3 × 6 = 18 4 × 6 = 24 5 × 6 = 30 6 × 6 = 36
1 × 7 = 7 2 × 7 = 14 3 × 7 = 21 4 × 7 = 28 5 × 7 = 35 6 × 7 = 42 7 × 7 = 49
1 × 8 = 8 2 × 8 = 16 3 × 8 = 24 4 × 8 = 32 5 × 8 = 40 6 × 8 = 48 7 × 8 = 56 8 × 8 = 64
1 × 9 = 9 2 × 9 = 18 3 × 9 = 27 4 × 9 = 36 5 × 9 = 45 6 × 9 = 54 7 × 9 = 63 8 × 9 = 72 9 × 9 = 81
```
以上就是生成并打印Java乘法表的代码和结果。
### 回答3:
生成打印Java乘法表的代码如下所示:
```java
public class MultiplicationTable {
public static void main(String[] args) {
int tableSize = 9; // 乘法表的大小
for (int i = 1; i <= tableSize; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(j + " * " + i + " = " + i * j + "\t");
}
System.out.println();
}
}
}
```
以上代码生成了一个大小为9的乘法表,通过嵌套的两个循环实现了表格的打印。外层循环控制行数,内层循环控制列数。在内层循环中,通过乘法运算得到每个单元格的结果,并使用print语句打印到控制台上。同时,为了使打印的表格整齐,使用了制表符`\t`进行对齐。
运行上述代码,会在控制台打印出以下乘法表:
```
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
```
以上就是生成打印Java乘法表的代码实现。
