Applet notinited
I am trying to create an applet, but at the bottom of the screen (in the status bar) it says "Applet CheckerboardPatterns notinited". I am using some examples from my textbook, but I still cannot see what I am doing wrong. Any help is appreciated.
import java.awt.*;
import javax.swing.*;
public class CheckerboardPatterns extends JApplet
{
enum SquareColor{red, blue};
enum Squares{Square1, Square2, Square3, Square4, Square5, Square6,
Square7, Square8};
enum Patterns{shells, diagonals};
Patterns pattern;
Patterns currentPattern;
public void init()
{
int sideSize = (int)(3 + Math.random() * 6);
//int patternType = (int)(Math.random() * 2);
int patternType = 1;
int size = sideSize * sideSize;
switch (patternType)
{
case 0:
pattern = Patterns.diagonals;
break;
case 1:
pattern = Patterns.shells;
break;
}
}
public void paint(Graphics graphics)
{
switch(pattern)
{
case diagonals:
paintDiagonals(graphics);
break;
case shells:
// paintShells(graphics);
break;
}
final int LEFT_MARGIN = 50, TOP_MARGIN = 50, X_OFFSET = 5, Y_OFFSET = 15,
NAME_INDENT = 50;
graphics.drawString("Pattern: " + currentPattern.name(), LEFT_MARGIN + NAME_INDENT,
TOP_MARGIN - Y_OFFSET);
}
/*
private void paintShells(Graphics graphics)
{
}
*/
private void paintDiagonals(Graphics graphics)
{
String rowColNumber;
for (Squares row: Squares.values())
for (Squares col: Squares.values())
{
rowColNumber = "" + (row.ordinal() + 1) + "" + (col.ordinal() + 1);
paintSquare(graphics, row.ordinal(), col.ordinal(), rowColNumber);
}
}
private void paintSquare(Graphics graphics, int row, int col,
String label)
{
final int SIZE = 30;
int x = (col + 1) * SIZE, y = (row + 1) * SIZE, diagonal = row + col;
switch (diagonal % 2)
{
case 0:
graphics.setColor(Color.red);
break;
case 1:
graphics.setColor(Color.blue);
break;
}
graphics.fillRect(x, y, SIZE, SIZE);
graphics.setColor(Color.white);
x += SIZE / 4;
y += SIZE / 2;
graphics.drawString(label, x, y);
}
}

OK, I have fixed my path and class path. Heres what they are set to:
Environment Variables
User Variables
CLASSPATH=.;C:\Program Files\Java\jre1.6.0\bin;C:\java
PATH=C:\Program Files\Java\jdk1.6.0\bin
System Variables
CLASSPATH=.;C:\Program Files\Java\jre1.6.0\lib\ext\QTJava.zip
Path=%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\QuickTime\QTSystem\;c:\Program Files\Microsoft SQL Server\90\Tools\binn\;C:\Program Files\Java\jdk1.6.0\bin
At http://java.sun.com/developer/onlineTraining/new2java/ it shows an html file with the .class at the end:
<HTML>
<BODY>
<APPLET CODE=SimpleApplet.class WIDTH=200 HEIGHT=100>
</APPLET>
</BODY>
</HTML>
I took the .class out of my html file and I am still getting this in the Java Console:
Java Plug-in 1.6.0

I cannot figure out why I'm still getting the Applet CheckerboardPatterns notinited.
