use Java

use JUnit 4 -> test

explain every method

Part 1: Longest run Write a java method (with appropriate method name, return type and argument lists) and accompanying main function to test it. Your program generates a sequence of 20 random die tosses in an array and prints the die values, marking only the longest run, like this: 1 2 5 5 3 1 2 4 3 (2 2 2 2) 3 6 5 5 6 31 If there is more than one run of maximum length, mark the first one. Use java Random class and don't hardcode the sequence of numbers. Make the best decision about how the code should be split between two methods. Write Junit tests
