Java Program To Demonstrate Awt Choice Control

Algorithm Steps:

Step 1: Write a html applet tag with code property set to the class name and comment it

Step 2: Import necessary packages and classes

Step 3: Define a class that extends applet and implements item listener

Step 4: Declare a choice fonts

Step 5: In the init() method, do the following:

            i) Declare the choice control

            ii) Populate the control with various font names

            iii) Add item listener to the choice

            iv) add the fonts choice to the applet

Step 6: In the itemStateChanged method repaint the applet

Step 7: In the paint() method do the following:

           i) Get the selected choice item

           ii) Create a font of the selected item value

           iii) Set the font of the graphics of the applet to the created font

           iv) Display any text on the applet

Java Program To Demonstrate Awt Choice Control
