运行以下代码: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) + "\t"); } System.out.println(); } }}

这段代码是打印九九乘法表的Java程序。运行这段程序,会在控制台上输出以下内容:
```
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
```
这个程序使用了两个嵌套的`for`循环来打印九九乘法表。外层循环控制行数,内层循环控制列数。在内层循环中,使用字符串拼接来生成乘法表达式,并使用制表符`\t`来对齐输出。最后,在每行结尾处,使用`System.out.println()`来换行。这样,就可以在控制台上输出九九乘法表了。

public class Main { public static void main(String[] args) { int size = 5; for (int i = 0; i < size; i++) { for
(int j = 0; j < size; j ) { System.out.print("*"); } System.out.println(); } }}
The code above is incomplete and will not run as it is missing the increment statement for the loop variables i and j.
A corrected version of the code would be:
public class Main {
public static void main(String[] args) {
int size = 5;
for (int i = 0; i < size; i++) {
for (int j = 0; j < size; j++) {
System.out.print("*");
}
System.out.println();
}
}
}
This code will print a square made of asterisks with a size of 5x5.
public class Test{ public static void main(String[] args){ for(int i=1;i<=10;i++){ if(i%3==0){ continue: System.out.print(i+"_____");
这段代码存在一些语法错误,正确的代码应该是这样的:
```
public class Test {
public static void main(String[] args) {
for (int i = 1; i <= 10; i++) {
if (i % 3 == 0) {
continue;
}
System.out.print(i + "_____");
}
}
}
```
代码的功能是打印出1到10之间不是3的倍数的数字,每个数字之间用"_____"分隔开来。运行上面的代码,会输出以下结果:
```
1_____2_____4_____5_____7_____8_____10_____
```
