Question
help create a Java recursive method that determines if a number is a prime number
![**Do the following:**
Create a recursive method `computePrime(int x, int y)` that returns a boolean value. The method should:
- Return true if `x` is a prime number; otherwise, return false.
- `y` is the current divisor to check.
Prompt the user to enter a number to check if it is prime.
Make the first call from the main function, setting `y` equal to 2. Example: `primeno = computePrime(number, 2);`
**Base cases:**
- If `x < 2`, return false.
- If `x == 2`, return true.
- If `x % y == 0`, return false.
- If `y * y > x`, return true.
- Otherwise, check for the next divisor:
- `return computePrime(x, y + 1)`
Demonstrate the method in a program (either in the same program or a separate one).
Test the program to ensure it runs correctly.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1dc718c6-fdb5-4fee-963d-d6ee33e5340a%2Ff66845fc-7bb5-4b8c-9468-a5cfe7b5971f%2Ft4yfmo_processed.png&w=3840&q=75)
