Question

The purpose of this assignment is to prove that you can build and use an arraylist.

Create a project named LastnameFirstnameHW7.

The purpose of your program is show that you can build and use an arraylist. The program will function a lot like Homework 6. The program should operate as follows:

Enter a name or 'Q' to quit: Tamaya
Enter a name or 'Q' to quit: Doug
Enter a name or 'Q' to quit: Lakshmi
Enter a name or 'Q' to quit: Q
The names you entered are: Tamaya, Doug, Lakshmi.

You must use a loop and an arraylist for this program. Assignments submitted without a loop and an arraylist will not be graded.

DO NOT use an array to complete this progam. You must create and use an arraylist.

Hint: it is easier to use a While loop than a For loop for this assignment.
Hint: you can use a boolean variable (see ArrayDemo.java example code) to keep track of whether to iterate your loop again

Explanation / Answer

import java.util.*;

import java.io.*;

class Test{

public static void main(String args[]){

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

Scanner sc=new Scanner(System.in);

System.out.println("Enter a name or 'Q' to quit:");

String s=sc.next();

if(s.equals("Q"))

{

System.exit(0);

}

while(!s.equals("Q"))

{

a_list.add(s);

System.out.println("Enter a name or 'Q' to quit:");

s=sc.next();

}

System.out.println("The names you entered are: ");

Iterator itr=a_list.iterator();

while(itr.hasNext())

{

   System.out.println(itr.next());

   }

}

}
