How would one go about creating a JTextArea in which you can copy the text that is set?

Simple, Cntl-C or right-click copy is fine.

Code is for a tile game I am working on and it prints information to the TextArea. Its works great, except I cannot copy any of the text.

import javax.swing.*;

import java.awt.*;

JTextArea has a default behavior where you could do ctrl + c to copy the text to the clip board.

Below is the code that I just copied from your above question and I ran it. Ctrl + C still works fine.

Or else you could use something like the one in the below code.

Keymap km = area.getKeymap();

KeyStroke ks = KeyStroke.getKeyStroke(KeyEvent.VK_C, InputEvent.CTRL_DOWN_MASK);

km.addActionForKeyStroke(ks, TransferHandler.getCopyAction());

Try:

String str;

str =TTextarea.getText();

This worked for me (same as Raghav's answer, but it maps copy to Command-C instead of Control-C, which is what most Mac users expect).

String osName = System.getProperties().getProperty("os.name");

if (osName.startsWith("Mac OS X")) {

    Keymap km = area.getKeymap();

    KeyStroke ks = KeyStroke.getKeyStroke(KeyEvent.VK_C,

        InputEvent.META_DOWN_MASK);

    km.addActionForKeyStroke(ks, TransferHandler.getCopyAction());

}
