Question

In java:

4. Using non-generic techniques, implement a static method getMax() that takes an array of type Comparable and returns the maximum element in the array.
(i.e. "public static Comparable getMax(Comparable [] anArray)").
5. Using the generic techniques to specify super-class relationships, implement a type safe version of the method in 4 named getMaxGen().

Answer 1

        public static Comparable getMax(Comparable [] anArray) {
                Comparable max = anArray[0];
                
                for(int i=0; i<anArray.length; i++) {
                        if(anArray[i].compareTo(max) > 0) {
                                max = anArray[i];
                        }
                }
                
                return max;
        }
        
        public static <T extends Comparable<T>> T getMaxGen(T [] anArray) {
                T max = anArray[0];
                
                for(int i=0; i<anArray.length; i++) {
                        if(anArray[i].compareTo(max) > 0) {
                                max = anArray[i];
                        }
                }
                
                return max;
        }
