this.something = something - problem with "double"

I have a rather simple problem, but I can't solve it somehow.

Code :

---

class lokomotiva extends element{
 
	public lokomotiva(double maxMasa){
 
		super(maxMasa);
 
		this.maxMasa = maxMasa;
 
	}
}

---

when i try to compile the whole thing (this is just a part of the code), I get an error:
possible loss of precision
found :double
required: int
at: this.maxMasa = maxMasa

maxMasa is a double number, and I want it to be, but how to assign it to an object?

Any help would be appriciated

I'm guessing that maxMasa in the element class is an int, can you verify the type in the element class?

I don't know how could I have missed that. It works now. Thx m8.
