public boolean equals(java.lang.Object obj)
equals
in class Expression
obj
- the Object to test for equality.
public int hashCode()
Expression
Expression.equals(Object)
method
on how two expressions can be equal if their expression Strings are different. Recall that if
two objects are equal according to the equals(Object) method, then calling the hashCode
method on each of the two objects must produce the same integer result. Implementations must
take special note and implement hashCode correctly.
