public static void printString(String s)
        String a = "Hello, ";
        String b = "Amigo!";

        String s = a + b;

        printString (s);
//      System.out.println();

    public static void main(String[] args) {
        // printString(a + b);

        printString("Hello, Amigo!");

        // printString(s);
    }
}
