Java call setter in constructor

Question

I am validating input data in setter method and don't want to validate it again in constructor. I wonder if calling the setter in the constructor is good idea?

Calling a setter from a constructor works just fine. Promotes code reuse.

Yes, you can call setter in constructor.

Sample() {
    setName("name");
}

it's not prohibited

You can do that. It's possible, but I would also suggest you to check forum link.

Generally considered safe, with the following caveat:

the only possible trouble you can get into is if the setter (or any method you call from a constructor) is overridden in a sub class. To be absolutely safe (paranoic?), make sure that all methods called from a constructor are final.
