Ternary Operator Limits [duplicate]

Question

Let's say we have following if statement:

int a = 1;
int b = 2;

if(a < b) {
    System.out.println("A is less than B!");
}
else {
    System.out.println("A is greater or equal to B!");
}

I have been wondering that if ternary operator replaces if statement when if statement consists from one line of code in each sub-block (if and else blocks), then why above example is not possible to write like this with ternary operator?

(a < b) ? System.out.println("A is less than B!") : System.out.println("A is greater or equal to B!");

Answer 1

You can only use ? : for expressions, not statements. Try

System.out.println(a < b ? "A is less than B!" : "A is greater or equal to B!");

Note: this is also shorter/simpler.
