Step 1: Understanding the Problem

Let’s first understand the problem. We need to create a function that takes an input in hours and returns the equivalent number of seconds. To convert hours to seconds, we can use the following formula:

Seconds = Hours × 60 × 60

Here are some examples to illustrate the desired behavior:

howManySeconds(2) ➞ 7200
howManySeconds(10) ➞ 36000
howManySeconds(24) ➞ 86400

Step 2: Creating the Function

Now that we understand the problem, let’s start by creating a function in Java. We’ll name our function howManySeconds and declare it with the following syntax:

public static int howManySeconds(int hours) {
    // Function body goes here
}

This function takes an integer as an argument (hours) and returns an integer. The public keyword means that the function can be accessed from anywhere in our code, while static means that we don’t need to create an object of the class to use this function.
