Front End Web Development Techdegree Graduate 84,738 PointsIf the method has a return type, you have to return something with that type, otherwise the compiler and hopefully your IDE will yell at you. So if you have a method:
public int multiply(int a, int b) {
return a * b;
}
I have to return an int because I said in the method signature I would return an int. Exactly what int I return is up to the use case, Java doesn't have an opinion on that.
