It's a ternary operation.

  

something = somecondition ? thing1 : thing2

is the same as 

something = null;

if (somecondition) {
    something = thing1;
}

else {
    something = thing2;
}

 

So in your example in the title, it's effectively setting wagePerPiece to the wage, or 0 if wage is negative.
