HashCode
How would I add objects so I could get the hash code value for all of them.
Here is my code Code:
/**
* Return a hash code value for this object using the algorithm from Bloch:
* fields are added in the following order: title, year, director.
*/
public int hashCode() {
int result = _title.hashCode();
return result;
}

I don't have much experience with hashcode, but you could try the xor operator(^):
Code:
/**
* Return a hash code value for this object using the algorithm from Bloch:
* fields are added in the following order: title, year, director.
*/
public int hashCode() {
int result = _title.hashCode();
result ^= year.hashCode();
result ^= director.hasCode();
return result;
}
However, I think there are better ways to do that.
