//Use parameters

import java.applet.*;
import java.awt.*;

/*
 * <applet code="Passing_Parameters_To_Applets" width=300 height=80>
 * <param name="fontName" value="Courier">
 * <param name="fontSize" value="14">
 * <param name="leading" value="2">
 * <param name="accountEnabled" value="true">
 * </applet>
 */
public class Passing_Parameters_To_Applets extends Applet
{
    String fontName;
    int fontSize;
    float leading;
    boolean active;

    //Initialize the string to be displayed
    public void start()
    {
        String param;

        fontName=getParameter("fontName");
        if(fontName==null)
        {
            fontName="Not Found";
        }

        param=getParameter("fontSize");
        try
        {
            if(param!=null)  //if not found
            {
                fontSize=Integer.parseInt(param);
            }
            else
            {
                fontSize=0;
            }
        }
        catch(NumberFormatException e)
        {
            fontSize=-1;
        }

        param=getParameter("leading");
        try
        {
            if(param!=null)  //if not found
            {
                leading=Float.valueOf(param).floatValue();
            }
            else
            {
                leading=0;
            }
        }
        catch(NumberFormatException e)
        {
            leading=-1;
        }

        param=getParameter("accountEnabled");
        if(param!=null)
        {
            active=Boolean.valueOf(param).booleanValue();
        }
    }
    //Display parameters
    public void paint(Graphics g)
    {
        g.drawString("Font Name: "+fontName, 0, 10);
        g.drawString("Font Size: "+fontSize, 0, 26);
        g.drawString("Leading: "+leading, 0, 42);
        g.drawString("Account Active: "+active, 0,58);
    }

  • [This](http://docs.oracle.com/javase/tutorial/deployment/applet/param.html) may be of use to you. – Azar Nov 03 '14 at 12:15
  • The applet is apparently not being launched using the HTML defined in the Java source code. What is the content of the HTML that launches it? – Andrew Thompson Nov 03 '14 at 22:02
  • 1) Why code an applet? If it is due to the teacher specifying it, please refer them to [Why CS teachers should **stop** teaching Java applets](http://programmers.blogoverflow.com/2013/05/why-cs-teachers-should-stop-teaching-java-applets/). 2) Why use AWT? See [this answer](http://stackoverflow.com/questions/6255106/java-gui-listeners-without-awt/6255978#6255978) for many good reasons to abandon AWT using components in favor of Swing. – Andrew Thompson Nov 03 '14 at 22:02

Instead of using getParameter(), you should use this.getParameter(). I think that would work!
