Pictorial Presentation:

Java: Print an American flag on the screen

Sample Solution:

Java Code:

public class Exercise14 {
 
   public static void main(String[] args) {
        // Print a pattern of asterisks and equal signs to create a design
        System.out.println("* * * * * * ==================================");
        System.out.println(" * * * * *  ==================================");
        System.out.println("* * * * * * ==================================");
        System.out.println(" * * * * *  ==================================");
        System.out.println("* * * * * * ==================================");
        System.out.println(" * * * * *  ==================================");
        System.out.println("* * * * * * ==================================");
        System.out.println(" * * * * *  ==================================");
        System.out.println("* * * * * * ==================================");
        
        // Print a row of equal signs to complete the design
        System.out.println("==============================================");
        System.out.println("==============================================");
        System.out.println("==============================================");
        System.out.println("==============================================");
        System.out.println("==============================================");
        System.out.println("==============================================");
    }
}

Sample Output:

* * * * * * ==================================

* * * * * * ==================================                                                                
==============================================                                                                
==============================================

==============================================                                                                
==============================================

Sample Solution:

Java Code:

public class Main {
    public static void main(String[] args) {
        // Define pattern strings for the top and middle sections
        String p1 = "* * * * * * ==================================\n * * * * *  ==================================";
        String p2 = "==============================================";
        // Print the top section pattern 4 times
        for (int i = 0; i < 4; i++) {
            System.out.println(p1);
        }
        // Print the bottom section pattern once
        System.out.println("* * * * * * ==================================");
        // Print the middle section pattern 6 times
        for (int i = 0; i < 6; i++) {
            System.out.println(p2);
        }
    }
}

Output:

* * * * * * ==================================
 * * * * *  ==================================
