Display 15.2 A Node Class

public class Node1
{

private String item;
private int count;
private Node1 link;

A node contains a reference to another node.
That reference is the link to the next node.

public Node1( )
{
link = null ;
item = null ;
count = 0;
}
public Node1(String newItem, int newCount, Node1 linkValue)
{
setData(newItem, newCount);
link = linkValue;
}

We will define a number of node classes so we
numbered the names as in Node1 .

public void setData(String newItem, int newCount)
{

item = newItem;
count = newCount;
}
public void setLink(Node1 newLink)
{
link = newLink;
}

We will give a better definition of a
node class later in this chapter.

public String getItem( )
{

return item;

}

public int getCount( )
{

return count;

}

public Node1 getLink( )
{

return link;

}
}
