Which of the following statements are true about correctly overriden hashCode() and equals() methods?

1) the equals() must return the same value as using the == operator
2) equals() and hashCode() code must return the same value.
3) If two objects are different according to equals() they will return different hashCode() values.
4) If two objects are equal according to equals() they will return the same hashCode value.

Kindly let me know the correct answer


Thanks,
Shekar
