AIM: To write a java program to demonstrate the Flow Layout
PROCEDURE
STEP1:Open Netbeans IDE and Select File->New project.
STEP2:Select Java ->Java Application, then click on Next .
STEP3:Give a name to your project and click on Finish.
PROBLEM STATEMENT
• Write a html applet tag with code set to class name and comment it
• Import all necessary packages and classes
• Define a class that extends Applet
• Declare an array of buttons and three panels
• In the init() method of the applet do the following:
i) Set the layout of the applet to Grid layout that can hold three columns
ii) Create the array of buttons
iii) Add a panel, set the layout to Flow layout to add buttons from the center
iv) Add the buttons to the panel
v) Similarly create two more panels and set layout to flow layout to add the
buttons from the left and right of the flow layout
vi) Add the buttons in to these panels

Include the applet tag with code set to the class name of the applet as comment
Import all the required packages and classes
Define class which extends Applet and implements ActionListener
Declare buttons green, red, blue, red and font
Declare msg of type String and initialize to "VISTAS"
Declare a Textarea area
In the init method of the applet, do the following
i) Set the layout to border layout
ii) Create area object and set its text to msg and add it to the center of the
borderlayout
iii) Create green button and add it to the north of borderlayout. Similarly, create red,
blue,font buttons and add them to south,east, west of border layout.
iv) Add action listener to all the buttons
In the actionperformed method do the following
i) Get the action command of a button pressed in a string str
ii) If str is equal to any one of the color button's text then set the foreground to that
color.
iii) If str is equal to font then create a new font of type Garmond and set the area's
font to the newly created font
iv) Repaint the applet
write the paint method with no body (empty paint method)
