java
![### Question 14
Analyze the code snippet below to identify syntax errors and potential runtime errors:
```java
public static void main(String[] args) {
char again;
String input;
Scanner keyboard = new Scanner(System.in);
do
{
double num1, num2;
System.out.print("Enter a number: ");
num1 = keyboard.nextDouble();
System.out.print("Enter another number: ");
num2 = keyboard.nextDouble();
if ( num1 > 100 || < 10 )
System.out.println("???");
System.out.println("Their sum is " + (num1 + num2));
System.out.println("Their division is " + num1 / num2);
System.out.print("Do you wish to do this " +
"again? (Y/N) ");
input = keyboard.readLine();
again = input.charAt(0);
} while (again == 'Y' || again == 'y');
}
```
#### Lines Containing Syntax Errors
Identify the specific lines that contain syntax errors:
- **Line 12**: There should be a semicolon (;) at the end of the `do` statement.
- **Line 18**: The condition in the 'if' statement should be `if (num1 > 100 || num1 < 10)`.
- **Line 27**: `keyboard.readLine()` should be replaced with `keyboard.nextLine()`.
Fill in the blanks with the correct line numbers:
- Line 12
- Line 18
- Line 27
#### Line That May Cause Runtime Error
Identify the line that may cause a runtime error:
- **Line 23**: This line can potentially cause a division by zero if `num2` is zero, resulting in an ArithmeticException.
Fill in the blank with the correct line number:
- Line 23](https://content.bartleby.com/qna-images/question/0e6f6223-c696-4938-9015-1aa854831435/deea4d6f-3f2a-4766-b43d-ca2a3543145a/iymqqnp_processed.png)
