Question
Complete the following Additional Activity for the Hailstone Series lab.Implement a new static method declared as follows:1234567891011/** * Repeatedly asks the user for a positive integer until the user enters * one. Returns the positive integer. * * @param in * the input stream * @param out * the output stream * @return a positive integer entered by the user */private static int getPositiveInteger(SimpleReader in, SimpleWriter out) {...}
Solution
Here is a simple implementation of the getPositiveInteger method in Java:
private static int getPositiveInteger(SimpleReader in, SimpleWriter out) {
int input;
do {
out.println("Please enter a positive integer: ");
input = in.nextInt();
if (input <= 0) {
out.println("That's not a positive integer. Try again.");
}
} while (input <= 0);
return input;
}
This method uses a do-while loop to repeatedly ask the user for a positive integer until one is entered. If the user enters a non-positive integer, the method prints an error message and asks for another input. The loop continues until a positive integer is entered, at which point the method returns the input.

Justin needs a program to generate and analyze the Hailstone Sequence for a specific positive number up to 1. Hailstone Sequences follow these rules: If a number is even, divide it by 2. If a number is odd, multiply it by 3 and add 1.Help Justin by writing a program using a function to calculate the Hailstone sequence.
