Why does this code fail in command line?

Question

I am using the "ListDemo" from the java swing tutorial. If I compile it on the command line
javac ListDemo.java
It compiles fine. Then when I run it, it says:
C:\Development\Java\Projects\Projects>java ListDemo
Exception occurred during event dispatching:
java.lang.NoSuchMethodError
at ListDemo.createAndShowGUI(ListDemo.java:196)
at ListDemo.access$400(ListDemo.java:7)
at ListDemo$1.run(ListDemo.java:217)

at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.run(Unknown Source)
Yet when I load up the same file into Netbeans, it compiles and runs fine! Here is the file:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;

Answer 1

You are not running this code under JDK 1.4
The setDefaultLookAndFeelDecorated method requires JDK 1.4 version.
