In this case, String will be passed to T. Comparator defines the following two methods: int compare(T objA, T objB) boolean equals(Object obj) Of these, only compare( ) must be implemented. The equals( ) method simply specifies an override of equals( ) in Object. Implementing equals( ) enables you to determine if two Comparators are equal. However, this capability is not always needed. When it is not needed (as it is not in the examples in this chapter), there is no need to override Object’s implementation.
Create a Comparator that returns the outcome // of a reverse string comparison. class RevStrComp implements Comparator
One string is greater than another if it comes after the other in alphabetical order. 15 16 He rb Sc h i ldt ’s Java P rog ra m m i n g Cookbook The compare( ) method of RevStrComp returns the result of the call to compareTo( ). However, notice that compare( ) calls compareTo( ) in reverse order. That is, compareTo( ) is called on strB with strA passed as an argument. For a normal comparison, strA would invoke compareTo( ), passing strB. However, because strB invokes compareTo( ), the outcome of the comparison is reversed.
