Hi, You can refer to issue 60745. What do you say if you can create the functionality like this. public int hashCode() { int hash = 1; hash = hash * 31 + someNonNullField.hashCode(); hash = hash * 31 + (someOtherField == null ? 0 : someOtherField.hashCode()); return hash; } You iterator all not-trasient members and generate the code, there have some rules i believe you know as well. I list them here just for the safe side. Calculate hashcode for data type long, calculate (int)f ^ (f >>> 32)) float, Float.floatToIntBits(f) double, Double.doubleToLongBits(f) Object, if is null, =0, or return its own hashCode() Same thing to equals() and toString(). It would be a great help if you can apply it. Thanks
