Question

For each of the following write the line(s) of code that:

1. Declares and initializes (creates) an ArrayList that holds String objects

2. Adds to your ArrayList the words "Too" and "Fun"

3. Verifies that your ArrayList now contains 2 elements

4. Sets the second String in the ArrayList to "No"

5. Verifies that your ArrayList still contains exactly 2 elements

6. Prints the contents of the ArrayList to the screen in the following format:

   <element>, <element>, . . . , <element>

Answer 1

The programming language used is python 3.8

1)Declaring the ArrayLIst:

The code in python : ArrayList = []

2)Adding string values to ArrayList:

The code in python:

ArrayList.append("Too")
ArrayList.append("Fun")

3)Verifying ArrayList has 2 elements:

This is done by printing the values in ArrayList.The python code is:

for value in ArrayList:
    print(value,end=" ")

4)Setting the second string in ArrayList to "No"

The index of second string in ArrayList will be 1.

So the python code is:

ArrayList[1]="No"

5)Verifying ArrayList has 2 elements:

This is done by printing the values in ArrayList.The python code is:

for value in ArrayList:
    print(value,end=" ")

6)Printing of the contents in ArrayList can be done using the code:

for value in ArrayList:
    print(value,end=" ")

The python code snippet is provided below:

ArrayList=[]
ArrayList.append("Too")
ArrayList.append("Fun")
for value in ArrayList:
    print(value,end=" ") #To verify there are 2 contents in array list
ArrayList[1]="No"
print("")
for value in ArrayList:
    print(value,end=" ") #To verify there are 2 contents in array list

print(" ")
#To print the contents
for value in ArrayList:
    print(value,end=" ")
