![### Question 29
Choose the missing code for lines 2, 9, and 17 in the following program to generate a random number in the range of 10 and the number that the user inputs through the keyboard.
#### Code Snippet:
```java
import java.util.Scanner;
import --------------------;
public class Q3_2 {
public static void main(String [] args) {
int x, num;
Scanner keyboard = new Scanner(-------------);
Random rand1 = new Random();
System.out.print("Please enter a positive integer: ");
x = keyboard.nextInt();
num = ---------------------;
System.out.println(num);
}
}
```
#### Missing Code Options:
A. `java.util.Random, system.in, nextInt(x + 10)`
B. `java.util.Random, System.in , rand1.nextInt(x) + 10`
C. `java.util.Random, keyboard, rand1.nextInt(x+10)`
D. `java.util.*, keyboard, rand1.nextInt(x) + 10`
**Explanation:**
The code above is designed to prompt the user to enter a positive integer, then generate and print a random number in the range of 10 and the entered positive integer. To complete the code, we need to choose the correct imports and method calls.
**Correct Answer:**
**D. java.util.*, keyboard, rand1.nextInt(x) + 10**
**Explanation:**
1. The `import java.util.*;` statement allows you to import all classes from the `java.util` package, which includes both `Scanner` and `Random`.
2. `new Scanner(System.in);` correctly initializes the `Scanner` to take input from the keyboard.
3. `rand1.nextInt(x) + 10` generates a random number between 0 (inclusive) and `x` (exclusive) and adds 10 to it, ensuring the result is within the range 10 to (x + 10) - 1.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0e6f6223-c696-4938-9015-1aa854831435%2F14245bcc-ad4f-4714-afd2-2d34975cce5f%2Ff3x1j9v_processed.png&w=3840&q=75)
