Add each of the Beth . Jerry . Rick Summer Morty 2 Write for each loop (enhanced for loop) to display all the string objects on a separate new line (After printing the contents of the array, print a blank new line for formatting) 3 Add "Jessica" so that it is the 4'h name in the ArrayList. Now add "Jerry" into the third position in the list (there will be two identical strings "Jerry in the list).

(After printing the contents of the array, print a blank new line for formatting) 4 5 Write a traditional for loop to remove "Jerry" and display the revised Array List. 6 In the comments text box in the Blackboard assignment link answer the following questions: was "Jerry" removed completely from the list?

Explanation / Answer

The code for Array List satisfying all the conditions is given below:

Code: -

import java.util.*;

class CustomerListerArrayList

{

public static void main(String[] args)

{

//Part 1

ArrayList<String> customername=new ArrayList<String>();

customername.add("Beth");

customername.add("Jerry");

customername.add("Rick");

customername.add("Summer");

customername.add("Monty");

//Part 2

Iterator itr=customername.iterator();  

while(itr.hasNext())

{  

System.out.println(itr.next());  

}

System.out.println(" ");

System.out.println(" ");

  

//Part 3

// as the list starts its index from 0, use add(index,"Value")

customername.add(2,"Jerry");

customername.add(3,"Jessica");

//Part 4

Iterator itr2=customername.iterator();  

while(itr2.hasNext())

{  

System.out.println(itr2.next());  

}

}

}

Save the file as CustomerListerArrayList.java and then using command prompt use the basic commands to compile(javac CustomerListerArrayList.java) and execute (java CustomerListerArrayList).
