📌 Information & Algorithm

Given Input:

Expected Output:

💻 Program Code

public class NthPrimeNumber {
    public static void main(String[] args) {
        int n = 10;
        int count = 0, num = 1, i;

        while (count < n) {
            num++;
            for (i = 2; i <= num / 2; i++) {
                if (num % i == 0) {
                    break;
                }
            }
            if (i > num / 2) {
                count++;
            }
        }
        System.out.println("The " + n + "th prime number is: " + num);
    }
}

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
