You shouldn't have setters in the first place. What's the point of encapsulation if anyone can just set properties at will?

  Sometimes the value you pass to a setter can go through additional logic to determine the final value to be set e.g.: private int value1; private int value2; public void setValue2(int value2) { this.value2 = value2; } public void setValue1(int value1) { if (this.value2 > 0) { this.value1 = value1 + this.value2; } else { this.value1 = value1; } } Obviously this is a contrived example but if you have logic other than a simple "this.value = value", then you might want to unit test that bit.

    Also useful if you want to add logging, or capture some metrics, or set a breakpoint.

    Ah, the sound of people not using their type system properly. Parse, don't validate.

      But also don’t create AggregateNonNegativeInteger type when generics will do.
