Can I throw exception in constructor?

Question

I just want to add some constraints on the object.
I'm thinking to add the constraints to the constructor, when every time create a new object , check first. If obey the rule, that's fine. If not, just throw it? Can I do like this way??
e.g Class Distance
Distance(x){if x >= 0.0  dist = x  else throw...}
float dist;
}

Answer 1

The best exception to throw in that case is IllegalArgumentException..
class Distance {
    float dist;
    Distance(float x) {
        if (x < 0.0) {
            throw new IllegalArgumentException("x must be non-negative");
        dist = x;
}
