I have a Generic Class with two type variables, which implements java.lang.Comparable.
public class DoubleKey<K,J> implements Comparable<DoubleKey<K,J>>{ private K key1; private J key2; public DoubleKey(K key1, J key2){ this.key1 = key1; this.key2 = key2; } public K getFirstKey(){ return this.key1; } public J getSecondKey(){ return this.key2; } // need for Comparable interface public int compareTo(DoubleKey<K,J> aThat){ ... } }
Becuase i implemeted it with Comparable, I need to write the compareTo() method. Because K, J can be of ANY type, I'm having problems on how to compare them completely. Is there a way to be able to catch all possible types (Primitive, Wrapper, Object) in the comparison? Thanks for the help!
