- For any element in keysList with a value greater than 40, print the corresponding value in itemsList, followed by a semicolon (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20;30; import java.util.Scanner; public class Compare { public static void main(String args[]) {final int SIZE_LIST = 4;int[] keysList = new int[SIZE_LIST];int[] itemsList = new int[SIZE_LIST];int i;Scanner input = new Scanner(System.in); keysList[0] = input.nextInt();keysList[1] = input.nextInt();keysList[2] = input.nextInt();keysList[3] = input.nextInt(); itemsList[0] = input.nextInt();itemsList[1] = input.nextInt();itemsList[2] = input.nextInt();itemsList[3] = input.nextInt(); /* Your code goes here */ System.out.println();} }Write an application that displays the strings in the provided array alphabetically in ascending order import java.util.*; public class StringSort { public static void main(String[] args) { String[] values = {"mouse", "dog", "cat", "horse", "cow", "moose", "tiger", "lion", "elephant", "bird", "hamster", "guinea pig", "leopard", "aardvark", "hummingbird"}; } } I need help with this!Write an application that displays the strings in the provided array alphabetically in ascending order. import java.util.*; public class StringSort { publicstaticvoidmain(String[] args) { String[] values = {"mouse","dog","cat","horse","cow", "moose","tiger","lion","elephant","bird","hamster", "guinea pig","leopard","aardvark","hummingbird"}; }

- Please complete the task by yourself only in JAVA with explanation. Don't copy. Thank you. Using quicksort to sort an array of car objects by various criteria. Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } c) Implement a comparator called CompareCarsByMakeThenDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByMakeThenDescendingMPG should return a value that will cause quicksort to sort an array of cars in ascending order by make and, when two cars have the same make, in descending order by mpg.Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = courseGrades.length - 1. import java.util.Scanner; public class CourseGradePrinter {public static void main (String [ ] args) {Scanner scnr = new Scanner(System.in);final int NUM_VALS = 4;int [ ] courseGrades = new int[NUM_VALS];int i; for (i = 0; i < courseGrades.length; ++i) {courseGrades[i] = scnr.nextInt();} /* Your solution goes here */ }}Write Java program that reads array of integers. Calculate the sum of all integers that cointain at least one digit 4. Write Java program that read array of strings. Print all strings that contain at least three characters 's'.
- Write Java statements that finds the count of strings that are less than the String object str in an array of strings.Do not write whole program, write only the statements necessary to perform the task described above. with javaFor any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces).
