Answer 1

You are asking me to do your homework, but still. I will give you only the pseudo code, you will have to write it on your own.

1. Write a JFrame.
2. Add a JLabel to the JFrame (using a label is easier than using a text pane, and it is impossible to use a text area).
3. Add a Key Listener to either the JFrame or the JLabel depending on your application.
4. In the handler write code to add a ImageIcon to the JLabel when the key you want is pressed or whatever.

Cheers!

You can't use a JTextArea since it can only display text.

You can use a JTextPane as it supports the display of Icons.

Check out: Auto Replace Smiles. It shows how to replace the two text characters :) with an Icon.
