• If you want to write a string, then add a drawString statement to the paint method, defined in a subclass of the JComponent class, by instantiating the following pattern:

  graphics context.drawString(a string, x, y); 
  

• If you want to determine the height of a font or the width of a string, then create an instance of the FontMetrics class using the graphics context, and then examine that instance's instance variables by instantiating the following patterns:

  FontMetrics fontMetrics = graphics context.getFontMetrics();  
  ... 
  fontMetrics.getHeight()                  <-- Fetch height 
  ... 
  fontMetrics.stringWidth(a string);       <-- Fetch width 
  

• If you want to change to a different font, then instantiate the following pattern:

  graphics context.setFont(new Font(name, Font.style, size)); 
  

  The name is a string, such as "Helvetica". The style is the name of a Font class variable, such as BOLD. The size is an integer specifying size, such as 12, for a 12-point font.
