X$975$: Build Two Nodes

Using this class definition:

$1$

public class node $\{$

$2$

$//...$ instance variables

$3$

public node$($E d$,$ node n$)\{$

$4$

this.data $=$ d;

$5$

this.next $=$ n;

$6$

$\}$

$7$

public E getData$()\{$return data; $\}$

$8$

public void setData$($E d$)\{$data $=$ d; $\}$

$9$

public node getNext$()\{$return next; $\}$

$10$

public void setNext$($node n$)\{$next $=$ n; $\}$

$11$

$\}$

Complete the method build$2$Nodes that creates two objects of type node, and places the values of the a and b parameters in these nodes. The first node $($a$)$ should have its next field point to the second node created $($b$).$ The method should return the head of the list created, that is the pointer to the node with the value in a$.$

Your Answer:
