Example: Solid Rectangle Star Pattern in Java

// Solid Rectangle Star Pattern
import java.util.Scanner;

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

        // Step 1: Prompt user for the number of rows
        System.out.print("Enter the number of rows for the solid rectangle: ");
        int rows = scanner.nextInt();

        // Step 2: Prompt user for the number of columns
        System.out.print("Enter the number of columns for the solid rectangle: ");
        int cols = scanner.nextInt();

        System.out.println("\nSolid Rectangle Pattern:");

        // Step 3: Outer loop iterates through each row
        for (int i = 0; i < rows; i++) {
            // Step 4: Inner loop iterates through each column in the current row
            for (int j = 0; j < cols; j++) {
                // Step 5: Print an asterisk for every position
                System.out.print("*");
            }
            // Step 6: After printing all columns for a row, move to the next line
            System.out.println();
        }

        scanner.close();
    }
