I have tried many different ways ... see commented out code
public static void main(String[] args) {
a = "Hello, ";
b = "Amigo!";
printString("Hello, Amigo!");
// printString(s);
// printString(a + b);
}
public static void printString(String s)
// System.out.println (s);
// a = "Hello, ";
// b = "Amigo!";
// nope System.out.println(s);
// nope System.out.println s;
}
