String content = "It is a beautiful day.";
String[] results; // Declare empty String array
results = match(content, "orange");
// The match statement above will fail to find
// the word "orange" in the String 'content', so
// it will return a null value to 'results'.
if (results == null) {
println("Value of 'results' is null."); // This line is printed
} else {
println("Value of 'results' is not null!"); // This line is not printed
}
