Java – ternary operator does not work

NetBeans says my ternary operator is not a declaration How?

int direction;
direction = (Math.random() < 0.5) ? 0 : 1; // direction is either L or R (0 or 1)
direction == 0 ? System.out.print('L') : System.out.print('R');

I've tried that it corresponds to if / then / else and it works properly:

int direction;
direction = (Math.random() < 0.5) ? 0 : 1; // direction is either L or R (0 or 1)
if(direction == 0){
    System.out.print('L');
} else {
    System.out.print('R');
}

Solution

Statements in ternary operators must be invalid They need to return something

System.out.println(direction == 0 ? 'L' : 'R');
