Create an implementation of LinkedList provided.
- Create an implementation of LinkedList provided.
- For each implementation create a tester to verify the implementation of that
data structure performs as expected
Your task is to:
- Create a client ( a class with a main ) ‘StagBusClient’ which builds a bus route by performing the following operations on your linked list:
- Create (insert) 4 stations
- List the stations
- Check if a station is in the list (print result)
- Check for a station that exists, and one that doesn’t
- Remove a station
- List the stations
- Add a station before another station. List the stations
- Add a station after another station. Print the stations
LinkedList.java
package linkedList;
public interface LinkedList {
public Boolean isItemInList(String thisItem);
// true if it is, false if not
public Boolean addItem(String thisItem);
// true if added, false if it was already there, or an error
public Integer itemCount();
public void listItems();
public Boolean deleteItem(String thisItem);
// true if deleted, false if not there or error
public Boolean insertBefore(String newItem, String itemToInsertBefore);
public Boolean insertAfter(String newItem, String itemToInsertAfter);
//ExtraCredit
public void sort();
// ascending alphanumeric sort; nothing fancy but ALTERS THE LIST, DOES NOT COPY.
}
// Implement this interface using class ListItem
// Also implement the tester in this package.
LinkedListImpl.java
package linkedList;
public class LinkedListImpl implements LinkedList {
}
LinkedListTest.java
package linkedList;
public class LinkedListTest {
public static void main(String[] args) {
// create implementation, then...
}
}
ListItem.java
package linkedList;
public class ListItem {
public String data;
public ListItem next;
public ListItem(String data) {
this.data = data;
this.next = null;
}
}
