PREREQUISITE:
Basic knowledge of Java language and loops.
ALGORITHM:
1. Take the number of rows and columns as input from the user and store them in variables ('rows' and 'cols').
2. Run a loop 'rows' times to iterate through the rows (i=0 to i<rows).
3. Inside the outer loop, run another loop 'cols' times to iterate through the columns (j=0 to j<cols).
4. Print '*' for each column in the current row.
5. Move to the next line after each row has been printed.
Code in Java:
import java.util.Scanner;
public class RectanglePattern {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter the number of rows for the rectangle:");
int rows = scanner.nextInt(); // Taking input for number of rows
System.out.println("Enter the number of columns for the rectangle:");
int cols = scanner.nextInt(); // Taking input for number of columns
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
System.out.print("*"); // Printing '*' for each column in the current row
}
System.out.println(); // New line after each row
}
scanner.close();
}
}
Output:
Enter the number of rows for the rectangle:
4
Enter the number of columns for the rectangle:
6
