Write a public instance method named countPositive that takes a Scanner object as its only argument, and returns an int. The method's header should look like this:

public int countPositive$($Scanner input$)$

Assume that the Scanner object is connected to a file that contains a series of integers $($one per line$),$ which the method will read. $($The file is already opened, and the Scanner object is ready to read the file.$)$

The countPositive method should do the following:

Recursively count the number of positive integers in the file $($greater than $0).$

Return the total count of positive integers.

For example, if the file contains the following numbers:

$5$

$-9$

$7$

$0$

Then, calling countPositive should return $2,$ because there are two positive numbers: $5$ and $7.$

Do not use loops $($like for, while, or do$-$while$)$ in your solution. Use only recursion.

Note: Assume the file contains at least one number.

$16$

$17$

$18$

$19$

$20$
