Fail PrintingTest printStarsTest1 (#Exercise 39.1)

[bishesh acharya]

My code:
public class Printing {

    public static void printStars(int amount) {
        //
    }

    public static void printSquare(int sideSize) {
        //
    }

    public static void printRectangle(int width, int height) {
        //
    }

    public static void printTriangle(int size) {
        //
    }

    public static void main(String[] args) {
        // Tests do not use main, yo can write code here freely!
        // if you have problems with tests, please try out first
        // here to see that the printout looks correct
        printStars(5);
        printStars(3);
        printStars(9);
        System.out.println(" ---");  // printing --- to separate the figures
        printSquare(4);
        System.out.println(" ---");
        printRectangle(5,6);
        System.out.println(" ---");
        printTriangle(3);
        System.out.println(" ---");
    }
  
}

Hey,

Error says that method printStars must print line break after printing the stars, so simply writing System.out.println(); to the end of printStars method, that problem should then be fixed. But you also need to remove extra line breaks from your other methods.

Best regards,

Joni

Thank you, I had System.out.println(""); in every method call and kept getting 90% but doing it your way got me the correct solution and made the code much more intuitive

I was adding `System.out.print("\n");` but it was expecting `System.out.println();`, and it took me two hours to figure it out. 😁 😂😛🤓

I too, getting 90% test ok by adding line break in all others methods, finally solved. 😁 😂
