Question

Revise SimpleLinkedListTest

Revise the file SimpleLinkedListTest.java given in the lecture in the following ways:

• Create and populate a single linked list int values

• Use this list to test each method you implement in the following ways

  o Haveatleast1testcaseforsuccessfulcallingthetestedmethod
  o Haveatleast1testcaseforunsuccessfulcallingthetestedmethod.Forexamplecallingthemethod

  public int get(int index) and passing an invalid index.

• NOTE: since the code here is mainly for testing purpose, you do NOT HAVE to use the user input when

  populating the list and testing your methods.

---------CODE SImpleLinkedListTest------------

package 1234;

public class SimpleLinkedListTest {

public static void main(String[] args) {
  
SimpleLinkedList numbers = new SimpleLinkedList();
  
  
numbers.add(10);
numbers.add(20);
numbers.add(30);
  

System.out.println(numbers.toString());
  
//System.out.println(numbers);
}   
  
}

Answer 1

1. Original List

2. Successful calling of the method:

3. Unsuccessful (invalid Test case)
