Optional<T>

HockeyPlayer

Code To Implement

CompareUtils

class:	CompareUtils.java
methods:	min
package:	compare.group
source folder:	student/src/main/java

min

public static <E> Optional<E> min(E[] array, Comparator<E> comparator)

Tip: To create an Optional<E>, do the following: Optional.of(E value).

CompareApps

class:	CompareApps.java
methods:	closestTo youngest mostPoints
package:	compare.group
source folder:	student/src/main/java

closestTo

Warning: THIS SHOULD BE A ONE LINE SOLUTION! You should be calling CompareUtils.min()

public static Optional<Integer> closestTo(Integer[] values, int target)

Return a call to CompareUtils.min() which contains an index within an Optional. Use a lambda to define a comparator as the second parameter to min(). What computation should this comparator return?

youngest

public static Optional<HockeyPlayer> youngest(HockeyPlayer[] players)

mostPoints

public static Optional<HockeyPlayer> mostPoints(HockeyPlayer[] players)

How can you make it so a call to min() ends up returning the max instead? 🤔

Testing Your Solution
