Java 8 brought an excellent new java. Affordable solution to train a team and make them project ready. But there are ways if you want to get unique values from the ArrayList and each way is explained with an example. To get the minimum or maximum value from the array we can use the Collections.min() and Collections.max() methods. In the below example, we have created an ArrayList with the size of Integer.MAX_VALUE. It accepts an object of ArrayList as a parameter to be sort and returns an ArrayList sorted in the ascending order according to the natural ordering of its elements. Example of finding Maximum Value in Map. Let us see a program to find the maximum element of ArrayList with Java collections , Enjoy unlimited access on 5500+ Hand Picked Quality Video Courses. https://docs.oracle.com/javase/8/docs/api/java/util/stream/Stream.html, https://docs.oracle.com/javase/8/docs/api/java/util/stream/IntStream.html, https://docs.oracle.com/javase/8/docs/api/java/util/stream/Stream.html#max-java.util.Comparator-, https://docs.oracle.com/javase/8/docs/api/java/util/stream/Stream.html#collect-java.util.stream.Collector-, https://docs.oracle.com/javase/8/docs/api/java/util/stream/Stream.html#reduce-java.util.function.BinaryOperator-, https://docs.oracle.com/javase/8/docs/api/java/util/IntSummaryStatistics.html.
