On the previous page, we saw that to make our objects sortable, we need to make themimplement the Comparable interface. This means providing acompareTo()method that will define the order of two instances of a g
This method implements theSystem.IComparable<T>interface and performs slightly better than theChar.CompareTomethod because it does not have to convert thevalueparameter to an object. The comparison performed by this method is based on the encoded values of this instance andvalue, not their lexicogr...
The CompareTo method implements the IComparable interface. The value parameter must be null or an instance of Char; otherwise, an exception is thrown. The comparison performed by this method is based on the encoded values of this instance and value, not necessarily their lexicographical characterist...
From the JavaDoc for the compareTo method in the Comparable interface: It is strongly recommended, but not strictly required that(x.compareTo(y)==0) == (x.equals(y)). Generally speaking, any class that implements the Comparable interface and violates this condition should clearly indicate this...
The CompareTo method implements the IComparable interface. The value parameter must be nulla null reference (Nothing in Visual Basic) or an instance of Char; otherwise, an exception is thrown. The comparison performed by this method is based on the encoded values of this instance and...

On the previous page, we saw an example implementation of the compareTo() method of the Comparable interface. Our implementation was methodical and easy to follow, but a bit "long-winded". ...so long as we're careful!In some cases we can make the comparison method more succinct, but ...
