Components

 

These exercises should be carried out after working 

through the Components Tutorials

 You should carry out both exercises.

Exercise 1: Create Components

Exercise 2: Create the Menu


Exercise 1: Create Components

Examine the picture of the applet below.  There are a number of different components.  We have two labels, two text fields and 26 buttons. 

Create an applet with all the components shown above.  

Hint: I would suggest you create a panel, add the panel to the content pane of the applet and then add all the other components to this panel.  If you don't you will only see one component in the applet window.

You will notice that the arrangement of your components is different.  You will learn how to control your arrangement of your components in the next tutorial - Layout Managers.

 


Exercise 2: Create the Menu

The applet also has a menu.  The expanded menu looks like this:-

Hopefully you have already created a menu like this in the Containers exercise.  If not then go and do that now.

Add the code for creating your menu to the code you have written for the first exercise above.

 

Have fun!
