Create class Test in a file named Test.java. This class contains a main program that performs the following actions: Instantiate a doubly linked list. Insert strings “a”, “b”, and “c” at the head of the list using three Insert() operations. The state of the list is now [“c”, “b”, “a”]. Set the current element to the second-to-last element with a call to Tail() followed by a call to Previous()Then insert string “d”. The state of the list is now [“c”, “d”, “b”, “a”]. Set the current element to past-the-end with a call to Tail() followed by a call to Next(). Then insert string “e”. The state of the list is now [“c”, “d”, “b”, “a”, “e”] . Print the list with a call to Print() and verify that the state of the list is correct.

A loop that iteratively processes a given list is called a for construct. So long as there are things to process, it will keep running. To what extent is this statement accurate or false?

You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework.  The “data.txt” file has three lines of data  100, 110, 120, 130, 140, 150, 160  100, 130, 160  1@0, 2@3, 3@END  You need to   1. create an empty unsorted list  2. add the numbers from the first line to list using putItem() function.   Then print all the current keys to command line in one line using printAll().  3. delete the numbers given by the second line in the list by using deleteItem() function.  Then print all the current keys to command line in one line using printAll()..   4. putItem () the numbers in the third line of the data file to the corresponding location in  the list. For example, 1@0 means adding number 1 at position 0 of the list.  Then print all the current keys to command line in one…

Code NOT working. What to do?   Here is code:   appleList = [["Apple",52,14,0,0],["McIntosh red",80,18,0,0.5],["Gala (Apple)",52,11.4,0.2,0.3],["Fuji Apple",52,11.4,0.2,0.3],["Honey Crisp Apples",90,21,0,0],["Granny Smith Apples",52,11.4,0.2,0.3],["Red Delicious Apples",80,17,0,0],["Braeburn Apples",71.7,16,0.5,0.1],["Golden Delicious Apples",130,29,1,0],["Jonagold",130.7,34,1,0],["Cripps Pink Apple",80,18,0,0],["Empire Apples",80,17,0,0],["Produce Cortland Apples",70,6,1,5],["Jazz Apples",53.8,12,0.6,0.5],["Cameo Apples", 80,22,0,0]["Winesap Apples",80,22,0,0],["Rome Apples",80,22,0,0],["Ambrosia Apples",90,17,0.4,0],] print(":Type of Apple : Calories : Carbs (in GRAMS) : Protein (in GRAMS) : Fat (in GRAMS) :") for item in appleList:print(":",item[0]," "*(9-len(item[0])),":",item[1]," "*(13-len(item[1])),":",item[2]," "*(4-len(str(item[2]))),":")
