Oracle offers some java generics questions with solutions. That is drawback 8.

Write a generic methodology to seek out the maximal factor within the vary
[start, finish) of an inventory.

answer

import java.util.*;

public closing class Algorithm {
    public static <T extends Object & Comparable<? tremendous T>>
        T max(Record<? extends T> listing, int start, int finish) {

        T maxElem = listing.get(start);

        for (++start; start < finish; ++start)
            if (maxElem.compareTo(listing.get(start)) < 0)
                maxElem = listing.get(start);
        return maxElem;
    }
}

Within the methodology signature

public static <T extends Object & Comparable<? tremendous T>> T max(Record<? extends T> listing, int start, int finish)

What’s the level of stating that T should prolong Object? Does not every thing do this anyway? Is that this redundant?
