                 ----   Hello Web!   ----
         Practice Exercises (Joel Tohline 9/13/98)

Making only minor modifications in the earlier "Hello Web"
example(s), try adding color AND different type Fonts to
your applet.


---------------------------------------------------------------
---------------------------------------------------------------
NOTE:  Before compiling any one of the following examples, you
       MUST name the file containing your example code 
       "HelloWeb.java".  It's resulting (compiled) Java byte-code
       will then be called "HelloWeb.class".  
NOTE:  When running on the UNIX machine (baton or mleesun), don't
       forget to change the permission (using "chmod") on your
       "HelloWeb.class" file so that the above HTML file can
       actually run the applet from any web browser!
---------------------------------------------------------------


//Example #1.2.A:  
//      Straight from the textbook, but with predefined color.

public class HelloWeb extends java.applet.Applet {
   public void paint( java.awt.Graphics gc ) {
      gc.setColor( java.awt.Color.blue);
      gc.drawString("Hello Web!", 125, 95 );
   }
}

---------------------------------------------------------------

//Example #1.2.B:  Using a "static" (i.e., predefined) Color.

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

public class HelloWeb extends Applet {
   Color myColorChoice = Color.red; 

   public void paint( Graphics gc ) {
      gc.setColor(myColorChoice);
      gc.drawString("Hello Web!", 125, 95 );
/*
    NOTE:  The available "static" colors (Java version 1.0) are:
           Color.black      Color.green       Color.red
           Color.blue       Color.lightGray   Color.white
           Color.cyan       Color.magenta     Color.yellow
           Color.darkGray   Color.orange
           Color.gray       Color.pink

    See, for example, p. 189 of "Java in a Nutshell (version 1.0)".

   }
}

---------------------------------------------------------------
//Example #1.2.C:  Building your own Color.

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

public class Cf extends Applet {
   float red   = 0.5F; //Decimal numbers are type "double" unless
   float blue  = 0.5F; //   they are suffixed with an "F".
   float green = 0.0F;

   Color myBrightGreen = new Color(  0,  255,    0);
   Color myPurple      = new Color(red, green, blue);
  
   public void paint( Graphics gc ) {
      gc.setColor(myBrightGreen);
      gc.drawString("Hello Web!", 125, 95 );
      gc.setCol(myPurple);
      gc.drawString("I Prefer Purple", 25, 145 );
/*
    NOTE:  The java.awt.Color class provides 3 public "Constructors".
           Here we have used 2 of them:  
              public Color(  int r,   int g,   int b);
              public Color(float r, float g, float b);
    The integers r,g,b may have values between 0 and 255; the float
    numbers r,g,b may have values between 0.0 and 1.0  .

    See, for example, p. 243 of "Java in a Nutshell (version 1.0)".

   }

---------------------------------------------------------------

//Example #1.2.D:  
//      Changing to a differnt Font.

public class Ex1_2_D extends java.applet.Applet {
   public void paint( java.awt.Graphics gc ) {
      gc.setColor( java.awt.Color.blue  );
      gc.setFont( new java.awt.Font("Serif",java.awt.Font.BOLD,36)  );
      gc.drawString("Hello Web!", 125, 95 );
   }
}

---------------------------------------------------------------

//Example #1.2.E:  Using two different Fonts and Colors.

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

public class Ex1_2_E extends Applet {
   Color myBrightGreen = new Color(  0,  255,    0);
   Color myPurple      = new Color(0.5F,  0.0F,  0.5F);
   Font  bigTimesRoman = new Font("Serif",Font.BOLD,36);
   Font  fBI = new Font("Monospaced", Font.ITALIC + Font.BOLD, 12);
  
   public void paint( Graphics gc ) {
      gc.setColor(myBrightGreen);
      gc.setFont( fBI );
      gc.drawString("Hello Web!", 125, 95 );
      gc.setColor(myPurple);
      gc.setFont( bigTimesRoman );
      gc.drawString("I Prefer Purple", 25, 145 );
