Listing 1. HashCode sample.
public int hashCode() {
int result = super.hashCode(); // PICK ONE
//int result = 0; // PICK ONE
result = PRIME*result + primitiveField;
result = PRIME*result + (flagField ? 1 : 0);
result = PRIME*result + (int)(longField >>> 32);
result = PRIME*result + (int)(longField & 0xFFFFFFFF);
long temp = Double.doubleToLongBits(doubleField);
result = PRIME*result + (int)(temp >>> 32);
result = PRIME*result + (int)(temp & 0xFFFFFFFF);
result = PRIME*result + objectField.hashCode();
if (maybeNullField != null) {
result = PRIME*result + maybeNullField.hashCode();
}
for (int i = 0; i < arrayfield.length;="" ++i)="" {="" result="PRIME*result" +="" arrayfield[i].hashcode();="" }="" return="" result;="" }="">
