button to enable the Button C.” After this button is clicked, it
should disable itself and Button B.

button print to the screen when you click it." After this button
is clicked, it should print to the screen.

- Button C: set to Disabled and show the tooltip "Click this
button to enable the Button A and B.” After this button is
clicked, it should disable itself and at the same time, enable
Button A and B.Besides the three buttons above, create a text
area to allow the user to enter text using JTextArea. In the
initialisation, the text area will display “Welcome to Asean
