Java语言打印九九乘法表
### 回答1:
```java
public class MultiplicationTable {
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();
}
}
}
```
### 回答2:
使用Java代码打印九九乘法表,可以采用双层循环的方式实现。代码如下:
```
public class MultiplicationTable {
public static void main(String[] args) {
// 双层循环,外层循环控制行数,内层循环控制列数
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
// 打印表达式和结果
System.out.print(j + " * " + i + " = " + (i * j) + "\t");
}
// 换行
System.out.println();
}
}
}
```
运行上述代码,即可在控制台输出九九乘法表的结果。代码中的外层循环控制了行数,内层循环根据当前行数控制了列数。在循环内部通过打印表达式和结果的方式打印每一个乘法式子,每个式子之间通过制表符进行分隔,最后通过换行符换行。

以下是使用Java代码打印九九乘法表:
```java
public class MultiplicationTable {
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 + " = " + (j * i) + "\t");
}
System.out.println();
}
}
}
```
上述代码会输出一个九九乘法表,具体如下:
```
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
```
上述代码中,外层循环控制行数,内层循环控制列数,并通过乘法运算符 (*)计算出每个乘法表达式的结果。最后使用`\t`制表符保证表格对齐,`\n`换行符将结果输出到下一行。
