Expert Solution

Step 1

Given Code:

32.

public static double foxtrot(ArrayList<Integer> list) {
double p = 0.0;

for (int item: list){
p += item;

double q = p / list.size();
return q;
}

33.

public static int waltz (ArrayList<Integer> list) {
int temp = list.get(0);

for (int k = 1; k < list.size(); k++)
if (list.get(k) < temp)
temp = list.get(k);

return temp;
}

Question 2: Linked List Implementation You are going to create and implement a new Linked List class. The Java Class name is "StringLinkedList". The Linked List class only stores 'string' data type. You should not change the name of your Java Class. Your program has to implement the following methods for the StringLinked List Class: 1. push(String e) - adds a string to the beginning of the list (discussed in class) 2. printList() prints the linked list starting from the head (discussed in class) 3. deleteAfter(String e) - deletes the string present after the given string input 'e'. 4. updateToLower() - changes the stored string values in the list to lowercase. 5. concatStr(int p1, int p2) - Retrieves the two strings at given node positions p1 and p2. The retrieved strings are joined as a single string. This new string is then pushed to the list using push() method.
LAB: Finding an integer in a list (singly-linked list) Given main() and an IntNode class, complete the IntList class by writing the append() and search() methods. The search() method should return the IntNode whose data value matches a given key, and null if the key is not found. The search() method should also set the position of each IntNode searched in the IntList, starting with 1. Ex: If the input is: 12 23 59 37 923 2 -1 12 the output is: 12 found in list at position 1. If the input is: 12 23 59 37 923 2 -1 68 the output is: 68 not found in list. ______________________________________ import java.util.Scanner; public class SearchList {public static void main (String[] args) {Scanner scnr = new Scanner(System.in);IntList intList = new IntList();IntNode curNode, foundNode;int num, searchNum;num = scnr.nextInt();while (num != -1) {// Insert into linked listcurNode = new IntNode(num);intList.append(curNode);num = scnr.nextInt();}searchNum = scnr.nextInt();foundNode =…
