Uncovering the Secrets of Prime Numbers in Java
When it comes to programming in Java, understanding prime numbers is a fundamental concept. But what happens when you need to display prime numbers between two intervals? This is where things get interesting.
The Challenge: Checking Prime Numbers in an Interval
Imagine you’re tasked with finding all prime numbers between 0 and 10. Sounds simple, right? But what about the numbers 0 and 1? They’re not prime, so you need to exclude them from your search. This is where the while loop comes in handy.
The Power of Loops: A Deeper Look
To tackle this problem, you’ll need to use a combination of while and for loops. The outer while loop will iterate through each number in the interval, while the inner for loop will check whether each number is prime or not. But here’s the catch: you need to reset the value of flag = false on each iteration of the while loop. This ensures that you’re not carrying over any previous results.
The Code: A Step-by-Step Breakdown
So, what does the code look like? Let’s take a closer look:

As you can see, the inner for loop is where the magic happens. It checks each number to see if it’s prime, and if so, adds it to the list. But what about the outer while loop? That’s where the interval comes in.
Understanding the Interval
When checking for prime numbers in an interval, you need to set boundaries. In this case, we’re looking at numbers between 0 and 10. But remember, 0 and 1 aren’t prime, so we need to exclude them. This means our condition will look like this:

Taking it to the Next Level: Functions and More
But what if you want to take your prime number game to the next level? That’s where functions come in. By creating a function to display prime numbers between intervals, you can reuse your code and make it more efficient. Want to learn more?
