Question
Using java, answer the following questions about the code below.
1) Create a new function or method that checks to see if an int parameter is present in the list.
2) Create a main() method or JUnit tests to show that your list code functions as intended.
(Code)
private class Node
int data;
Node next;
Node(int data) {
this.data = data;
this.next = null;
}
}
private Node first;
private Node last;
public void addToEnd(int data){
Node newNode = new Node(data);
if (first == null){
first = newNode;
last = newNode;
} else {
last.next = newNode;
last = newNode;
}
}
public void printList(){
Node current = first;
while (current != null){
System.out.print(current.data + " ");
current = current.next;
}
System.out.println();
}
