Applet
I'm just trying to make a simple hello world applet with this code:
php Code:
Original - php Code 
  1.  
  2. import java.applet.*;
  3. import java.awt.*;
  4.  
  5. public class HelloWorld extends Applet
  6. {
  7.      public void init()
  8.      {
  9.  
  10.      }
  11.  
  12.      public void stop()
  13.      {
  14.  
  15.      }
  16.  
  17.      public void paint(Graphics g)
  18.      {
  19.       g.drawString("Hey hey hey",20,20);
  20.       g.drawString("Hellooow World",20,40);
  21.  
  22.      }
  23.  
  24. } 

But I'm getting this error:
java.lang.UnsupportedClassVersionError: HelloWorld (Unsupported major.minor version 49.0)

Thanks very much!

RE: Applet
this happens when you have two versions of java installed...
try
javac -version
java -version
