is it incorrect to define an hashcode of an object as the sum, multiplication, whatever, of all clas
- by devoured elysium
Let's say I have the following class:
class ABC {
private int myInt = 1;
private double myDouble = 2;
private String myString = "123";
private SomeRandomClass1 myRandomClass1 = new ...
private SomeRandomClass2 myRandomClass2 = new ...
//pseudo code
public int myHashCode() {
return 37 *
myInt.hashcode() *
myDouble.hashCode() *
... *
myRandomClass.hashcode()
}
}
Would this be a correct implementation of hashCode? This is not how I usually do it(I tend to follow Effective Java's guide-lines) but I always have the temptation to just do something like the above code.
Thanks
