Example Program

Here is a program that tests GenericNode.

public class GenericNodeTester
{
  public static void main (String args[])
  {
    GenericNode<Float> nodeA = new GenericNode<Float>( 5.5f );
    System.out.println("nodeA: " + nodeA );    
    nodeA.setValue( 5.0f );
    System.out.println("nodeA: " + nodeA );

    GenericNode<String> nodeB = new GenericNode<String>( "Good Dog Carl" );
    System.out.println("nodeB: " + nodeB );    
    nodeB.setValue( "The Cat in the Hat" );
    System.out.println("nodeB: " + nodeB );

    GenericNode<Integer> nodeC = new GenericNode<Integer>( 45);
    System.out.println("nodeC: " + nodeC );    
    nodeC.setValue( 55 );
    System.out.println("nodeC: " + nodeC );
  }
} 

To compile and run it, ensure that GenericNodeTester.java and GenericNode.java are in the same subdirectory (or part of the same project):

PS C:\Code> javac -Xdiags:verbose GenericNodeTester.java
PS C:\Code> java  GenericNodeTester
nodeA: 5.5
nodeA: 5.0
nodeB: Good Dog Carl
nodeB: The Cat in the Hat
nodeC: 45
nodeC: 55
PS C:\Code>  

The switch -Xdiags:verbose asks the compiler to print out verbose error messages.

public class GenericNodeTester
{
  public static void main (String args[])
  {
    GenericNode<Integer> nodeA = new GenericNode<Integer>( 5.5 );
    System.out.println("nodeA: " + nodeA );    
  }
}
