Example: Floyd's Triangle Pattern Program in Java

// Floyd's Triangle Pattern Program
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Initialize Scanner for user input
        Scanner scanner = new Scanner(System.in);

        // Step 2: Prompt user for the number of rows
        System.out.print("Enter the number of rows for Floyd's Triangle: ");
        int numRows = scanner.nextInt();

        // Step 3: Initialize a counter for the numbers to be printed
        int currentNumber = 1;

        // Step 4: Outer loop for controlling the number of rows
        for (int i = 1; i <= numRows; i++) {
            // Step 5: Inner loop for controlling elements in the current row
            // Each row 'i' has 'i' numbers
            for (int j = 1; j <= i; j++) {
                // Step 6: Print the current number followed by a space
                System.out.print(currentNumber + " ");
                // Step 7: Increment the number for the next print
                currentNumber++;
            }
            // Step 8: Move to the next line after completing a row
            System.out.println();
        }

        // Step 9: Close the scanner to prevent resource leaks
        scanner.close();
    }
