Is the following declaration of a HashMap valid: HashMap nums = new HashMap(); True False An enumeration can contain public constant variables True False An interface can extend as many interfaces as the programmer wants O True O False
What must be true about valid equals() and hashCode() methods? O 01.equals(02) = o1.hashCodel) == 02.hashCode() O 01.hashCode() == 02.hashCode = 01.equals(02) O !01.equals(o2) = 01.hashCode() != 02.hashCode() O 01.hashCode() != 02.hashCode() = !o1.equals(o2) O hashCode must have a low collision rate for the hash table to work correctly
Write Junit test class that :  Returns a hash code for this object instance. The approach described by Joshua Bloch in "Effective Java" . public int hashCode()  Overrides:hashCode in class java.lang.Object Returns:A hash code.
