Examples

Choosing a value:

void main() {
    int age = 20;
    String status = age >= 18 ? "adult" : "minor";
    IO.println(status);
 
    int count = 1;
    IO.println(count + (count == 1 ? " item" : " items"));
}

Output:

adult
1 item

Notes

The ternary operator is an expression and has a value; if is a statement. Nested ternaries are hard to read — for three or more cases a switch expression is better. When combined with string concatenation, wrap the ternary in parentheses.
