Duplicate Set This function will receive a list of elements with duplicate elements. It should add all of the duplicate elements to a set and return the set containing the duplicate elements. A duplicate element is an element found more than one time in the specified list. The order of the set does not matter. Signature: public static HashSet<Object> duplicateSet(ArrayList<Object> list) Example: INPUT: [2, 4, 5, 3, 3, 5] OUTPUT: {5, 3}
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 }
narmts Save Answer Write a Java program that uses ArrayList and Iterator. It should input from user the names and ages of your few friends in a loop and add into ArrayList. Finally, it should use Iterator to display the data in a proper format.

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?
