- For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }What is the difference between ArrayLists and arrays?The last part of the code is not completed. public static void displayArray(int[] list) { System.out.println("The sum resulting array is" + Arrays.toString(list)); } }

- The ArrayList is created using the following syntax: String[] array = {"red", "green", "blue"}; ArrayList list Display all the elements of this list using: a) foreach loop b) foreach method with lambda := new ArrayList(java.util.Arrays.asList(array));6. the grade is under 20 which is outlier, remove it from the array list. 7. Print array list using System.out.println() 8. Use indexOf to print index of 80. 9. Use get function. 10. What is the difference between get and index of? 11. Print the values of the array list using Iterator class. 12.. Delete all the values of the array list using clear function. 13. Print all the values of the array after you execute clear using System.out.println(). what is the result of using clear function? 14. What is the shortcoming of using array List?Consider the following list: ArrayList q; q = new ArrayList(Arrays.asList Complete the following code that gives the following output: 80 30 90 20 70 10 iter q.listIterator ( while(iter. ) { +" "); } System.out.println( = (10, 70, 20, 90, 30, 80)); );
