Method Details

equals

public final boolean equals(Object obj)

Compares two Subset objects for equality. This method returns true if and only if this and the argument refer to the same object; since this method is final, this guarantee holds for all subclasses.

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

• HashMap

hashCode

public final int hashCode()

Returns the standard hash code as defined by the Object.hashCode() method. This method is final in order to ensure that the equals and hashCode methods will be consistent in all subclasses.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object

See Also:

• Object.equals(java.lang.Object)
• System.identityHashCode(java.lang.Object)

toString

public final String toString()

Returns the name of this subset.

Overrides:

toString in class Object
