Node 0: 223,

Setters and Getters

The setter and getter for value work as expected:

public class NodeTester
{
  public static void main ( String[] args )
  {
    Node node0 = new Node( 223 );  
    Node node1 = new Node( 493 );
    Node node2 = new Node( 717 );

    System.out.println("Node 0: " + node0 + "Node 1: " + node1 + "Node 2: " + node2);
    
    node0.setValue( -34 );
    node2.setValue( node1.getValue() );

    System.out.println("After changes: ")
    System.out.println("Node 0: " + node0 + "Node 1: " + node1 + "Node 2: " + node2);  
  }
}
